IP Enable Override Static-Routes

The route to a destination is described by:

Routes dynamically learned through OSPF and RIP can override static routes. For the RIP protocol, you can disable this override behavior with the Override Static Routes parameter.

This parameter is invoked on a per-IP-interface basis. When it is invoked, RIP routing information received on the specified interface overwrites statically configured network/subnet routes, providing that the cost of the new route is cheaper.

Enter the interface address that you want to override static routes.

Valid Values: any valid IP address

Default Value: none

Select the Submit button.


IP Enable Override Default

This option is invoked on a per-IP-interface basis. When the Enable Override Default Value option is invoked, default RIP routes received on the interface identified by the interface address override the router's current default gateway, providing the cost of the new default is cheaper.

Enter the interface address that you want to enable default gateway override.

Valid Values: any valid IP address

Default Value: none

Select the Submit button.


IP Enable Packet-Filter

This parameter enables packet filtering on incoming traffic on this interface.

Packet filters work in the same way as access-controls. When the IP forwarder receives a packet, it checks to see whether any packet filters have been defined for it on the interface over which the packet arrives. If a filter exists, and the packet is not excluded by it, the packet passes through the access control list defined for the entire router (as it is done at present). If the packet is being forwarded, it passes through any access control list specified for outgoing traffic on the interface on which the packet is about to be sent out. In either case, the router discards all packets that are not explicitly included by a filter.

Enter the Packet filter name to be enabled.

Valid Values: any 16-character name.

You can include dashes (-) and underscores (_) in the name.

Default Value: none

Select the Submit button.


IP Enable Receiving RIP

This parameter enables the processing of RIP updates that are received on a particular interface. If this parameter is disabled, no RIP updates will be accepted on the interface.

Enter the interface address you want to process RIP updates.

Valid Values: any valid IP address

Default Value: none

Select the Submit button.


IP Enable Receiving Dynamic All

If you enable Receiving Dynamic All, the server will accept any dynamic default routes, static routes, network level routes, subnet routes, or host routes for the specified interface even if they have not been added previously in the RIP Route Acceptance panel.

Enable Receiving Dynamic All is enabled by default.

Enter the interface address you want to accept any dynamic routes.

Valid Values: any valid IP address

Default Value: none

Select the Submit button.


IP Enable Receiving Dynamic Hosts

If you enable the Receiving Dynamic Hosts option, the router will accept any host routes on the specified interface even if they have not been specified in an Add Accept-RIP-Route option.

This parameter is enabled by default.

Enter the interface address you want to process RIP host route updates.

Valid Values: any valid IP address

Default Value: none

Select the Submit button.


IP Enable Receiving Dynamic Nets

Enables the processing of network-level RIP updates that are received on the specified interface.

If you enable the Receiving Dynamic Nets option, the router will accept any network-level routes on the specified interface even though they have not been specified in an Add Accept-RIP-Route option.

Enter the interface address you want to receive RIP dynamic network-level route updates.

Valid Values: any valid IP address

Default Value: none

Select the Submit button.


IP Enable Receiving Dynamic Subnets

Enables the processing of subnetwork-level RIP updates that are received on the specified interface.

If you enable the Receiving Dynamic SubNets option, the router will accept any subnetwork-level routes on the specified interface even though they have not been specified in an Add Accept-RIP-Route option.

Enter the interface address you want to receive RIP dynamic subnet route updates.

Valid Values: any valid IP address

Default Value: none

Select the Submit button.


IP Enable Sending All-Routes

This parameter allows you to specify whether all routes should be included in the RIP updates that are sent out on the selected interface.

This action determines the contents of RIP updates that are sent out a particular interface. The effect of the Enable Sending option is additive. Each separate Enable Sending option specifies that a certain set of routes should be advertised from a particular interface. A route is included in a RIP update only if it has been included by at least one of the Enable Sending options. The routes enabled by Enable Sending All are:

Enter the interface address you want to send RIP all route updates.

Valid Values: any valid IP address

Default Value: none

Note: By default, when you first enable RIP, sending net-routes, sending subnet-routes, and sending host-routes are enabled for each interface, while sending static-routes and sending default routes are disabled.

Select the Submit button.


Sending Default-Routes

This parameter allows you to specify whether the default route should be included in the RIP updates that are sent out on the selected interface.

The effect of the Enable Sending option is additive. Each separate enable sending option specifies that a certain set of routes should be advertised from a particular interface. A route is included in a RIP update only if it has been included by at least one of the enable sending options. The Enable Sending Default-Routes option specifies that the default route (if one exists) should be included in RIP updates sent out on the interface identified by the interface address.

Enter the interface address you want to send RIP default route updates.

Valid Values: any valid IP address

Default Value: none

Note: Some settings of the Enable Sending options are redundant. For example, if you invoke Enable Sending Net-Routes, Enable Sending Subnet-Routes, and Enable Sending Host-Routes for a particular interface, there is no need to also specify Enable Sending Static-Routes (because each static route is a network-level, subnet, or host route).

By default, when you first enable RIP, sending net-routes, sending subnet-routes, and sending host-routes are enabled for each interface, while sending static-routes and sending default routes are disabled.

Select the Submit button.


IP Enable Sending Host-Routes

This parameter allows you to specify whether the host routes should be included in the RIP updates that are sent out on the selected interface.

If you enable the Receiving Host Routes option, the router will accept any host routes on the specified interface even though they have not been specified in an Add Accept-RIP-Route option.

The effect of the Enable Sending option is additive. Each separate enable sending option specifies that a certain set of routes should be advertised from a particular interface. A route is included in a RIP update only if it has been included by at least one of the Enable Sending options. The Enable Sending Host-Routes option specifies that all host routes should be included in RIP updates sent out on the interface identified by the interface address.

Enter the interface address you want to send RIP host route updates.

Valid Values: any valid IP address

Default Value: none

Note: Some settings of the Enable Sending options are redundant. For example, if you invoke Enable Sending Net-Routes, Enable Sending Subnet-Routes, and Enable Sending Host-Routes for a particular interface, there is no need to also specify Enable Sending Static-Routes (because each static route is a network-level, subnet, or host route).

By default, when you first enable RIP, sending net-routes, sending subnet-routes, and sending host-routes are enabled for each interface, while sending static-routes and sending default routes are disabled.

Select the Submit button.


IP Enable Sending Net-Routes

This parameter allows you to specify whether the network routes should be included in the RIP updates that are sent out on the selected interface.

The effect of the Enable Sending option is additive. Each separate enable sending option specifies that a certain set of routes should be advertised from a particular interface. A route is included in a RIP update only if it has been included by at least one of the Enable Sending options. The Enable Sending Network-Routes option specifies that all network-level routes should be included in RIP updates sent out the specified interface.

A network-level route is a route to a single class A, B, or C IP network.

Enter the interface address you want to send RIP network-level route updates.

Valid Values: any valid IP address

Default Value: none

Note: Some settings of the Enable Sending options are redundant. For example, if you invoke Enable Sending Net-Routes, Enable Sending Subnet-Routes, and Enable Sending Host-Routes for a particular interface, there is no need to also specify Enable Sending Static-Routes (because each static route is a network-level, subnet, or host route).

By default, when you first enable RIP, sending net-routes, sending subnet-routes, and sending host-routes are enabled for each interface, while sending static-routes and sending default routes are disabled.

Select the Submit button.


IP Enable Sending Poisoned-Reverse-Routes

Sending Poisoned-Reverse Routes is a technique used by RIP to improve convergence time when routes change.

Poison reverse is an enhancement to split horizon where routes learned from a neighbor are reported back to it with a cost of infinity (that is, the network is viewed as unreachable). The use of poison reverse is safer than split horizon alone because it breaks erroneous looping routes immediately. For complete details on the technique, refer to RFC 1058.

Use of this technique increases the size of RIP update messages. You may find it more acceptable to minimize routing overhead by accepting somewhat slower convergence.

This parameter allows you to specify whether the poisoned reverse routes should be included in the RIP updates that are sent out on the selected interface.

Enter the interface address you want to send RIP poisoned-reverse route updates.

Valid Values: any valid IP address

Default Value: none

Note: This technique is enabled by default.

Select the Submit button.


IP Enable Sending Subnet-Routes

This parameter allows you to specify whether the subnet routes should be included in the RIP updates that are sent out on the selected interface.

If you enable the Receiving Subnet-Route option, the router will accept any subnetwork-level routes on the specified interface even though they have not been specified in an Add Accept-RIP-Route option.

The effect of the Enable Sending option is additive. Each separate enable sending option specifies that a certain set of routes should be advertised from a particular interface. A route is included in a RIP update only if it has been included by at least one of the Enable Sending options.

The Enable Sending Subnet-Routes option specifies that all subnet routes should be included in RIP updates sent out on the interface identified by the interface address. However, a subnet route is included only if the interface specified by the interface address connects directly to a subnet of the same IP subnetted network.

Enter the interface address you want to send RIP subnetwork route updates.

Valid Values: any valid IP address

Default Value: none

Note: Some settings of the Enable Sending options are redundant. For example, if you invoke Enable Sending Net-Routes, Enable Sending Subnet-Routes, and Enable Sending Host-Routes for a particular interface, there is no need to also specify Enable Sending Static-Routes (because each static route is a network-level, subnet, or host route).

By default, when you first enable RIP, sending net-routes, sending subnet-routes, and sending host-routes are enabled for each interface, while sending static-routes and sending default routes are disabled.

Select the Submit button.


IP Enable Sending-Static-Routes

This parameter allows you to specify whether the static routes should be included in the RIP updates that are sent out on the selected interface.

If you enable the Receiving Static-Route option, the router will accept any statically configured routes on the specified interface even though they have not been specified in an Add Accept-RIP-Route option.

The effect of the Enable Sending option is additive. Each separate enable sending option specifies that a certain set of routes should be advertised from a particular interface. A route is included in a RIP update only if it has been included by at least one of the Enable Sending options. The Enable Sending Static-Routes option specifies that all statically configured and directly connected routes should be included in RIP updates that are sent out the interface that is identified by the interface address.

Enter the interface address you want to send RIP static route updates.

Valid Values: any valid IP address

Default Value: none

Note: Some settings of the Enable Sending options are redundant. For example, if you invoke Enable Sending Net-Routes, Enable Sending Subnet-Routes, and Enable Sending Host-Routes for a particular interface, there is no need to also specify Enable Sending Static-Routes (because each static route is a network-level, subnet, or host route).

By default, when you first enable RIP, sending net-routes, sending subnet-routes, and sending host-routes are enabled for each interface, while sending static-routes and sending default routes are disabled.

Select the Submit button.


IP Enable UDP-Forwarding

Allows the forwarding of locally delivered UDP datagrams (such as broadcast packets) to UDP ports that were configured using the Add UDP-Destination option.

Enter the UDP port number you want to enable UDP-forwarding on.

Valid Values: an integer in the range of [0 - 65535]

Default Value: 0

Select the Submit button.


IP Add Accept-RIP-Route

You can define the nets or subnets for which your router will accept RIP updates.

This parameter allows an interface to accept a RIP route when input RIP filtering is enabled for the interface. You can print the list of networks/subnets that have already been entered using the List RIP Routes-Accept option. You can enable the input filtering of RIP routes on a per-IP-interface basis. This is done separately for:

To enable input filtering of routes on an IP interface, use the Enable Dynamic Nets/Subnets/Hosts options.

Enter the interface address from which you want the router to accept RIP route updates.

Valid Values: any valid IP address

Default Value: none

Select the Submit button.


IP Add Address

This parameter assigns an IP address to one of the router's hardware network interfaces. A hardware network interface will not receive or transmit IP packets until it has at least one IP address assigned to it.

IP allows you to use a serial line interface for IP traffic without assigning an IP address and subnet mask to the interface. However, you must still assign each serial line a label in the IP Address field. Use the format 0.0.0.n, where n is the hardware interface number.

Example   To specify a serial line whose hardware interface number is 2, you would specify 0.0.0.2 as the value for this parameter, and 2 as the value for the Interface Number. This address format tells the router that the interface is an unnumbered serial line.

Valid Values: For non-serial line interfaces:

For serial line interfaces: You must specify an IP address together with its subnet mask. For example, if the address is on a class B network, using the third byte for subnetting, the mask would be 255.255.255.0. Use the List Devices option to obtain the appropriate option interface-number.

  1. Enter the net number to which you want to add the address.

    Valid Values: a number in the range of [1 - 7]

    Default Value: none

  2. Enter the IP address you want to add.

    Valid Values: any valid IP address

    Default Value: none

  3. Enter the IP address mask of the address you want to add.

    Valid Values: 0.0.0.0 - 255.255.255.255

    Default Value: none
