Views IS-IS view Predefined user roles network-admin Parameters ipv6-prefix: Specifies an IPv6 prefix for the summary route. prefix-length: Specifies the length of the IPv6 prefix, in the range of 0 to 128. avoid-feedback: Avoids learning the summary route by route calculation. generate_null0_route: Generates a NULL 0 route to avoid routing loops. level-1: Summarizes only the routes redistributed to Level-1. level-1-2: Summarizes all the routes redistributed to both Level-1 and Level-2. level-2: Summarize only the routes redistributed to Level-2. tag: Specifies an administrative tag in the range of 1 to 4294967295. Usage guidelines If no level is specified, the command applies to Level-2. You can summarize routes with the same next hop into a single route to reduce the size of the routing table, as well as the size of the LSDB. This command can summarize both learned and redistributed IPv6 IS-IS routes. The cost of the summary route is the smallest cost of those summarized routes.
