1353BConfiguring RIPv2 route summarization
Perform this task to summarize contiguous subnets into a summary network and sends the network to
neighbors. The smallest metric among all summarized routes is used as the metric of the summary route.
1. Enabling RIPv2 automatic route summarization
Automatic summarization enables RIPv2 to generate a natural network for contiguous subnets. For
example, suppose there are three subnet routes 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24.
Automatic summarization automatically creates and advertises a summary route 10.0.0.0/8
instead of the more specific routes.
To enable RIPv2 automatic route summarization:

summarization.
summary
Optional.
By default, RIPv2 automatic route summarization is
enabled.
If the subnets in the routing table are not contiguous,
disable automatic route summarization to advertise
more specific routes.
2. Advertising a summary route
Perform this task to manually configure a summary route.
For example, suppose contiguous subnets routes 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24
exist in the routing table. You can create a summary route 10.1.0.0/16 on GigabitEthernet 0/1
to advertise the summary route instead of the more specific routes.

1354BDisabling host route reception
Perform this task to disable RIPv2 from receiving host routes from the same network and save network
resources. This feature does not apply to RIPv1.
