This chapter describes how to use the IPv6 configuration and operating commands and includes the following sections:
Use the following procedure to access the IPv6 configuration process.
* talk 6
Config>
After you enter the talk 6 command, the CONFIG prompt (Config>) displays on the terminal. If the prompt does not appear when you first enter configuration, press Return again.
To configure IPv6, enter the commands at the IPv6 Config> prompt.

This section describes dynamic reconfiguration (DR) as it affects Talk 6 and Talk 5 commands.
IP Version 6 (IPv6) supports the CONFIG (Talk 6) delete interface command with no restrictions.
IPv6 supports the GWCON (Talk 5) activate interface command with the following consideration:
If IPv6 was not configured before, you need to reboot.
All IPv6 interface-specific commands are supported by the GWCON (Talk 5) activate interface command.
IPv6 supports the GWCON (Talk 5) reset interface command with the following considerations:
All IPv6 interface-specific commands are supported by the GWCON (Talk 5) reset interface command.
IPv6 supports the following IPv6-specific GWCON (Talk 5) reset commands:
All IPv6 configuration changes are automatically activated except the
following:
| Commands whose changes are not activated by the GWCON, protocol ipv6, reset ipv6 command |
| CONFIG, protocol ipv6, set routing table-size |
| CONFIG, protocol ipv6, set reassembly-size |
| CONFIG, protocol ipv6, set cache-size |
IPv6 supports the following CONFIG commands that immediately change the
operational state of the device. These changes are saved and are
preserved if the device is reloaded, restarted, or you execute a dynamically
reconfigurable command.
| Commands |
| CONFIG, protocol ipv6, add route |
| CONFIG, protocol ipv6, delete route |
| CONFIG, protocol ipv6, change route |
| CONFIG, protocol ipv6, enable icmp-redirect |
| CONFIG, protocol ipv6, disable icmp-redirect |
| CONFIG, protocol ipv6, set access-control |
| CONFIG, protocol ipv6, set ttl |
| CONFIG, protocol ipv6, set path-mtu-aging-timer |
