rip set interface to-r6 version 2 type multicast
Importing a selected subset of routes from one of the RIP trusted gateways.
Router R1 has several RIP peers. Router R41 has an interface on the network
10.51.0.0. By default, router R41 advertises network 10.51.0.0/16 in its RIP updates.
Router R1 would like to import all routes except the 10.51.0.0/16 route from its peer
R41.
1. Add the peer 140.1.1.41 to the list of trusted and source gateways.
rip add source-gateways 140.1.1.41
rip add trusted-gateways 140.1.1.41
2. Create a RIP import source with the gateway as 140.1.1.4 since we would like to
import all routes except the 10.51.0.0/16 route from this gateway.
ip-router policy create rip-import-source ripImpSrc144 gateway 140.1.1.4
3. Create the Import-Policy, importing all routes except the 10.51.0.0/16 route from
gateway 140.1.1.4
ip-router policy import source ripImpSrc144 network all
ip-router policy import source ripImpSrc144 network 10.51.0.0/16 restrict
Importing a selected subset of routes from all RIP peers accessible over a certain inter-
face.
Router R1 has several RIP peers. Router R41 has an interface on the network
10.51.0.0. By default, router R41 advertises network 10.51.0.0/16 in its RIP updates.
Router R1 would like to import all routes except the 10.51.0.0/16 route from all its peer
which are accessible over interface 140.1.1.1.
1. Create a RIP import source with the interface as 140.1.1.1, since we would like to
import all routes except the 10.51.0.0/16 route from this interface.
ip-router policy create rip-import-source ripImpSrc140 interface 140.1.1.1
2. Create the Import-Policy importing all routes except the 10.51.0.0/16 route from
interface 140.1.1.1
ip-router policy import source ripImpSrc140 network all
ip-router policy import source ripImpSrc140 network 10.51.0.0/16 restrict
Example 2: Importing from OSPF
Due to the nature of OSPF, only the importation of ASE routes may be controlled.
OSPF intra-and inter-area routes are always imported into the SSR routing table with
a preference of 10. If a tag is specified, the import clause will only apply to routes with
the specified tag.
