Router advertisement

To configure the router to originate router advertisement messages on an interface, the interface must be configured under the router-advertisement context and be enabled (no shutdown). All other router advertisement configuration parameters are optional.

Router advertisement can be configured under the config>router>router-advertisement context or under the config>service>vprn>router-advertisement context. Use the following examples of CLI syntax to enable router advertisement and configure router advertisement parameters.

            - autonomous
            - on-link
            - preferred-lifetime {seconds | infinite}
            - valid-lifetime {seconds | infinite}
        - reachable-time milliseconds
        - retransmit-time milliseconds
        - router-lifetime seconds
        - no shutdown
        - use-virtual-mac

        - max-advertisement-interval seconds
        - min-advertisement-interval seconds
        - mtu mtu-bytes
        - other-stateful-configuration
            - autonomous
            - on-link
            - preferred-lifetime {seconds | infinite}
            - valid-lifetime {seconds | infinite}
        - reachable-time milliseconds
        - retransmit-time milliseconds
        - router-lifetime seconds
        - no shutdown
        - use-virtual-mac

The following example shows a router advertisement configuration:

*A:sim131>config>router>router-advert# info 
----------------------------------------------
            interface "n1"
                prefix 2001:db8:3::/64
                exit
                use-virtual-mac
                no shutdown
            exit
----------------------------------------------
*A:sim131>config>router>router-advert# interface n1 
*A:sim131>config>router>router-advert>if# prefix 2001:db8:3::/64 
----------------------------------------------
                    autonomous
                    on-link
                    preferred-lifetime 604800
                    valid-lifetime 2592000
