Description
Use the summary command to enable RIP-2 automatic route aggregation.
Use the undo summary command to disable RIP-2 automatic route aggregation.
By default, RIP-2 route aggregation is enabled.
Route aggregation can be used to reduce the routing traffic on the network as well as
to reduce the size of the routing table. If RIP-2 is used, route aggregation function can
be disabled with the undo summary command when it is necessary to broadcast
subnet routes.
RIP-1 does not support subnet mask. Forwarding subnet routes may cause ambiguity.
Therefore, RIP-1always uses route aggregation.
Related command: rip version.
Example
# Set RIP version on the interface Vlan-interface 10 as RIP-2 and disable route
aggregation.
