Using Rip Accept Policy - Avaya 8600 Technical Configuration Manual

4.8

Using RIP Accept Policy:

RIP Accept policies can be used on the Ethernet Routing Switch 8600 to selectively accept routes from
RIP updates. If no policies are defined, the default behavior is applied which will add all learned routes to
the route table.
A RIP Accept policy may be used to:

Listen to RIP updates only from certain gateways

Listen only for specific networks

Assign a specific mask to be included with a network in the routing table, i.e. network summary
In this example, we wish to use a RIP Accept policy on ERS8600A to create a single route that will point
to ERS8600C for all networks configured on it. The accept policy will take in any network from 10.1.192.0
to 10.1.255.0 and create a single entry in the routing table on ERS8600A.
In order to calculate the summary route, comparing the common bits in the address range derives the
summary address. In this example, the range of IP addresses is from 10.1.240.0 to 10.1.255.0.
The network address to use for this example will be 10.1.240.0/20.
1 Configure the IP Prefix List
config ip prefix-list "Prefix_1" add-
prefix 10.1.240.0/20 maskLenFrom 20
maskLenTo 32
2 Configure the Route Policy
config ip route-policy "rip_pol_1" seq 1
create
config ip route-policy "rip_pol_1" seq 1

ERS 8600 / ERS 8800 RIP Technical Configuration Guide
This command creates a Prelist list named Prefix_1 with
a IP range from 10.1.240.0 to 10.1.255.0
These commands configure a route policy named
"rip_pol_1" with match criteria using the IP Prefix
configured in Step 1. This will have the effect of injecting
one route of 10.1.240.0/20 into the route table.
