Parameters

ipv6-address: Specifies the destination IPv6 address of the summary route.

prefix-length: Specifies the prefix length of the destination IPv6 address, in the range of 0 to 128. This argument specifies the number of consecutive 1s of the prefix, which defines the network ID.

not-advertise: Specifies not to advertise the summary IPv6 route. Without this argument, the command advertises the IPv6 summary route.

cost value: Specifies the cost of the summary route, in the range of 1 to 16777215. The default cost is the largest cost value among routes that are summarized.

Usage guidelines

This command is available only on an ABR to summarize multiple contiguous networks into one network.

To enable ABR to advertise more-specific routes, issue the undo abr-summary command.

Examples
