Default Level

2: Configuration level

Usage Guidelines

This command is applicable only to the ABR for route aggregation of the current area. The ABR transmits only one summarized route to other areas.

An area can be configured with multiple summarized network segments. Thus OSPFv3 can summarize multiple network segments.

Example

# Summarize two routes FC00:0:0:1::/64 and FC00:0:0:2::/64 of OSPFv3 area 1 into route FC00:0:0::/48 with the cost being 400, and advertise it to other areas.
