Before configuring RIP routing feature, finish the following tasks:
■ Configure an IP address for each interface, and make sure all routers are
reachable.
■ Configure basic RIP functions
Configuring an
Additional Routing
Metric
An additional routing metric can be added to the metric of an inbound/outbound
RIP route, namely, the inbound and outbound additional metric.
The outbound additional metric is added to the metric of a sent route, the route’s
metric in the routing table is not changed.
The inbound additional metric is added to the metric of a received route before
the route is added into the routing table, so the route’s metric is changed.
Follow these steps to configure additional routing metric:
Configuring RIP-2 Route
Summarization
The route summarization means that subnet routes in a natural network are
summarized with a natural network that is sent to other networks. This function
can reduce the size of routing tables.
Configure RIP-2 route automatic summarization
Disable RIP-2 route automatic summarization if you want to advertise all subnet
routes.
Follow these steps to configure route automatic summarization:
