z

Redistribute external routes in an environment with multiple routing protocols.

Configuration Prerequisites

Before configuring RIP route control, perform the following tasks:

z

Configuring network layer addresses of interfaces so that adjacent nodes are reachable to each
other at the network layer

z

Configuring basic RIP functions

Configuring RIP Route Control

Setting the additional routing metrics of an interface

Additional metric is the metric added to the original metrics of RIP routes on an interface. It does not
directly change the metric value of a RIP route in the routing table of a router, but will be added to
incoming or outgoing RIP routes on the interface.

Follow these steps to set additional routing metric:

To do...

Use the command...

Remarks

Enter system view

system-view

Enter interface view

interface

interface-type interface-number

Set the additional routing metric to be
added for incoming RIP routes on this
interface

rip metricin value

Optional
0 by default

Set the additional routing metric to be
added for outgoing RIP routes on this
interface

rip metricout value

Optional
1 by default

The rip metricout command takes effect only on the RIP routes learnt by the router and the RIP routes
generated by the router itself, but the command is invalid for any route imported to RIP from other
routing protocols.

Configuring RIP route summarization

Rip route summarization means that when the router advertises RIP updates, different subnet routes in
the same natural network segment can be aggregated into one route with a natural mask for
transmission to another network segment. This function is used to reduce the routing traffic on the
network as well as the size of the routing table.

When it is necessary to advertise RIP route updates in a subnet, disable the route summarization for
RIP-2.

Follow these steps to configure RIP route summarization:

To do...

Use the command...
