This chapter describes Border Gateway Protocol (BGP) messages. For information on message content and how to use the message, refer to the Introduction.
| BGP.001 |
Level: UI-ERROR
Short Syntax: BGP.001 Bad sec code in OPEN, from neighbor
Long Syntax: BGP.001 BGP security code in OPEN message is incorrect from neighbor neighbor
Description: The BGP RFC specifies only a single acceptable security code of 0. This message is printed if another code is received.
Cause: Neighbor sent a security code in the OPEN message that is non null.
Action: Use a router that adheres more closely to the BGP specification.
| BGP.002 |
Level: UI-ERROR
Short Syntax: BGP.002 Bad msg hdr len, from neighbor
Long Syntax: BGP.002 BGP message header length is incorrect from neighbor neighbor
Description: The speaker received a message in which the header length was incorrect.
Cause: Neighbor sent an OPEN message that is of incorrect length.
Action: Use a router that adheres to the BGP specification.
| BGP.003 |
Level: U-INFO
Short Syntax: BGP.003 Unsupported BGP version, from neighbor
Long Syntax: BGP.003 Unsupported BGP version request from neighbor neighbor
Description: The current version supported by BGP is version 4. No other version support exists. This message is printed when a neighbor requests a lower version of BGP.
Cause: Neighbor is requesting a version of BGP, which is unsupported.
Action: Neighbor router must be configured for the proper version.
| BGP.004 |
Level: UI-ERROR
Short Syntax: BGP.004 Bad marker fld, from neighbor
Long Syntax: BGP.004 Marker field is incorrect from neighbor neighbor
Description: The only supported marker field is 16 octets of all ones. This message is printed when any other value is received.
Cause: Neighbor is using an incorrect marker field.
Action: Use a router that adheres to the BGP specification.
| BGP.005 |
Level: UI-ERROR
Short Syntax: BGP.005 Bad AS num, from neighbor
Long Syntax: BGP.005 Bad AS number from neighbor neighbor
Description: This message is printed when the neighbor's AS number in OPEN message does not match the configured value for that neighbor.
Cause: Neighbor is using an AS that does not match the configured value.
Action: Make sure that the neighbor and this router have properly configured AS numbers.
| BGP.006 |
Level: UI-ERROR
Short Syntax: BGP.006 Bad BGP ID, from neighbor
Long Syntax: BGP.006 Bad BGP identifier from neighbor neighbor
Description: This message is printed when the neighbor and this speaker have the same BGP identifier. Since this is used to resolve TCP connection collisions, this is an illegal configuration.
Cause: Neighbor is using a BGP identifier that is the same as this one.
Action: Make sure that the neighbor and this router have properly configured BGP identifiers.
| BGP.007 |
Level: U-INFO
Short Syntax: BGP.007 Conn err to neighbor; clsg with notify
Long Syntax: BGP.007 Closing connection to neighbor neighbor with notification
Description: Some error in the connection Finite State Machine resulted in this message.
Cause: An error in the connection Finite State Machine resulted in connection termination.
Action: Note other connection errors that occur with this event.
| BGP.008 |
Level: U-INFO
Short Syntax: BGP.008 Conn err to neighbor; clsg with no notify
Long Syntax: BGP.008 Closing connection to neighbor neighbor without notification
Description: Some error in the connection Finite State Machine resulted in this message, usually because this speaker received a NOTIFICATION message and there is no reason to send another one back to the neighbor who sent this.
Cause: An error in the connection Finite State Machine resulted in connection termination.
Action: Note other connection errors that occur along with this one.
| BGP.009 |
Level: UI-ERROR
Short Syntax: BGP.009 Foreign close from neighbor sprt sourceport dprt destinationport
Long Syntax: BGP.009 Foreign close from neighbor neighbor source port sourceport destination port destinationport
Description: The speaker just received a foreign close.
Cause: Neighbor is issuing a close.
Action: Neighbor should issue a close after a notification or during BGP ID negotiation. If this is the case, no action is necessary. If a connection closes for reasons other than these, the neighbor is in error.
| BGP.010 |
Level: U-INFO
Short Syntax: BGP.010 Reinit BGP conn to neighbor
Long Syntax: BGP.010 Reinitialize the BGP connection to neigbor neighbor
Description: If a previous connection to this neighbor resulted in termination, the speaker reinitiates the connection. This message is printed when this occurs.
Cause: Speaker is reinitializing a connection to this neighbor after an initial failure.
Action: None, unless this happens many times with no connection to the neighbor.
| BGP.011 |
Level: U-INFO
Short Syntax: BGP.011 Conn to neighbor clsg with no notify
Long Syntax: BGP.011 Connection to neighbor neighbor closing with no notification
Description: Probably in response to a NOTIFICATION message received from the other end, the router is closing the BGP connection to the neighbor without sending a notify.
| BGP.012 |
Level: UI-ERROR
Short Syntax: BGP.012 No conn listen can be done
Long Syntax: BGP.012 No connection listen can be done
Description: Something is preventing the speaker from issuing a listen.
Cause: Probably an internal error in the TCP subsystem. Also, the router could be low on memory.
Action: Check for low memory. If memory is low, check the BGP config statistics for memory utilization. A large number of neighbor connections can conceivably use up memory.
| BGP.013 |
Level: UI-ERROR
Short Syntax: BGP.013 TCP open fail to neighbor
Long Syntax: BGP.013 TCP open failure to BGP neighbor neighbor
Description: The BGP speaker initiates a tcp_listen request in order to receive connection requests from neighbors. This message is printed when the invocation to this function fails.
Cause: The open to the TCP subsystem failed.
Action: Serious problem. Check amount of heap memory available to router.
| BGP.014 |
Level: U-INFO
Short Syntax: BGP.014 Conn timer fired for neighbor
Long Syntax: BGP.014 Connection timer fired for neighbor neighbor
Description: A connection timer is used to continue attempts to make active connections from this speaker to this neighbor. The firing of this timer causes the speaker to quit the previous tcp_open and issue another tcp_open.
Cause: The connection timer fired because no neighbor connection was completed in the specified time.
Action: None. Connection process will continue until connection to neighbor completes.
| BGP.015 |
Level: U-INFO
Short Syntax: BGP.015 conn to neighbor open on sprt sourceport dprt destinationport

Short Syntax: BGP.016 OPEN sent to neighbor
Long Syntax: BGP.016 OPEN message sent to neighbor neighbor
Description: When a connection is opened, the speaker sends an OPEN message to the neighbor. This message is printed when this happens.
Cause: This is part of the connection process.
Action: None. This is an informational message.
| BGP.017 |
Level: UI-ERROR
Short Syntax: BGP.017 Bad msg len from neighbor sprt sourceport dprt destinationport
Long Syntax: BGP.017 Bad message length received from neighbor neighbor source port sourceport destination port destinationport
Description: The message length is checked when received. This message is printed if the length of the received message is smaller than the expected message header size.
Cause: This is probably caused by some device driver error or defect in the software either with the speaker or the neighbor.
Action: Determine if this happens with other neighbors. If yes, suspect some problem with this router; else, there is probably a problem with the neighbor. This is a serious error that might require information from many sources.
| BGP.019 |
Level: UI-ERROR
Short Syntax: BGP.019 Bad msg type from neighbor sprt sourceport dprt destinationport
Long Syntax: BGP.019 Bad message type from neighbor neighbor source port sourceport destination port destinationport
Description: BGP messages can be only of four types: OPEN, UPDATE, NOTIFICATION, and KEEPALIVE. This message is printed if the type is something other than the ones expected.
Cause: Since message types are among the most basic pieces of BGP information, this is probably the result of a garbled message.
Action: Determine if this happens with other neighbors. If yes, suspect some problem with this router; else, there is probably a problem with the neighbor. This is a serious error that requires information from many sources.
| BGP.020 |
Level: U-INFO

Level: UI-ERROR
Short Syntax: BGP.025 mand attr without trans bit set from neighbor, attr attribute_type
Long Syntax: BGP.025 mandatory attribute without transitive bit set from neighbor neighbor, attribute type attribute_type
Description: The neighbor has sent a mandatory attribute with the non-transitive bit set. This is a violation of the specification.
Cause: This is so basic to the protocol that the user would have to suspect some data corruption in the neighbor or the speaker.
Action: The user should suspect data corruption with the speaker or neighbor. Check the quality of link.
| BGP.026 |
Level: UI-ERROR
Short Syntax: BGP.026 Mand attr with partial bit set from neighbor, attr attribute_type
Long Syntax: BGP.026 Mandatory attribute with partial bit set from neighbor neighbor, attribute type attribute_type
Description: The neighbor has sent a mandatory attribute with the partial bit set. This is a violation of the specification.

| BGP.028 |
Level: UI-ERROR
Short Syntax: BGP.028 Origin path attr with bad len from neighbor, len length
Long Syntax: BGP.028 Origin path attribute has bad length from neighbor neighbor, length length
Description: The origin attribute must be one byte long. This attribute has a different length.
Cause: This is a basic protocol violation and the user should suspect data corruption in the neighbor or the speaker.
Action: The user should suspect data corruption with the speaker or neighbor. Check the quality of link.
| BGP.029 |
Level: UI-ERROR
Short Syntax: BGP.029 Origin path attr with bad type from neighbor, origin origin_type
Long Syntax: BGP.029 Origin path attribute with bad type from neighbor neighbor, origin origin_type

| BGP.031 |
Level: UI-ERROR
Short Syntax: BGP.031 Bad next hop attr len from neighbor, len length
Long Syntax: BGP.031 Next hop attribute with bad length from neighbor neighbor, length length
Description: The next hop should be the length of an IP address. This attribute has an incorrect length.
Cause: The neighbor has sent a next hop attribute with an incorrect length. This could be the result of data corruption.
Action: If the length field is completely garbled, suspect data corruption with the speaker or the neighbor. If the length field is off by a byte, suspect a protocol violation by the neighbor.
| BGP.032 |
Level: UI-ERROR
Short Syntax: BGP.032 Bad next hop attr from neighbor, next hop next_hop_attribute
Long Syntax: BGP.032 Bad next hop attribute from neighbor neighbor, next hop next_hop_attribute
Description: The next hop attribute is of proper length, but has been determined to be incorrect.
Cause: The neighbor has sent a next hop address, which is ours or a subnet address.
Action: If the address is our address, the neighbor is in definite violation of the protocol. If the address is a subnet, the neighbor is probably in violation.
