Configuring IPv6 IS-IS Route Summarization
Procedure
- Run system-view
The system view is displayed.
- Run isis [ process-id ]
The IS-IS view is displayed.
- Run ipv6 summary ipv6-address prefix-length [ avoid-feedback | generate_null0_route | tag tag | [ level-1 | level-1-2 | level-2 ] ] *
The specified IPv6 IS-IS routes are summarized into one IS-IS route.
After route summarization is configured on a device, the local routing table still contains all specific routes before the summarization. The routing tables on other devices contain only the summary route, and the summary route is deleted only after all its specific routes are deleted.
- Run commit
The configuration is committed.
