Configuring IPv6 IS-IS Route Summarization

Configuring IPv6 IS-IS Route Summarization

A large IS-IS network has a large number of routing entries. This will slow down routing table lookup and increase management complexity. You can configure route summarization to reduce the size of routing tables.

Pre-configuration Tasks

Before configuring IS-IS route summarization, complete the following task:

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run isis [ process-id ]

    The IS-IS view is displayed.

  3. 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.

    NOTE:

    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.

Verifying the Configuration

  • Run the display isis route command to check summary routes in the IS-IS routing table.

  • Run the display ipv6 routing-table [ verbose ] command to check summary routes in the IPv6 routing table.
