Resend route-map

Resend route-map

Tutorial steps and requirements: 1. Configure the IP addresses of each vro and run the ping command to check the connectivity of the direct ports of each vro. 2. Configure the OSPF and r12002 routing protocols according to the topology, and disable the automatic summary of r12002. 3. Configure route republishing on R2. 4. view the route tables of R1 and R3.

Configure route filtering on R2 to filter out ospf routes based on topology requirements. The configuration is as follows: R2 (config) # access-list 1 deny 172.16.0.0 0.0.255r2 (config) # access-list 1 deny 172.16.1.0 0.0.0.255R2 (co Nfig) # access-list 1 permit anyR2 (config) # route-map ospftorip permit 10 create a route-map and name it ospftorip. permit 10 indicates, if the conditions specified after the following match command are true, the action is allowed, and hidden conditions are rejected by default at the end. R2 (config-route-map) # match ip address 1 matches the network R2 (config-route-map) specified by acl 1 # exitR2 (config) # router ripR2 (config-router) # redistribute ospf 1 metric 10 route-map ospftorip when the route is re-published, reference the configured route-map to filter resending routes. 6. Check the route of R3 and confirm the route learning: R3 # sho ip routeGateway of last resort is not set 172.16.0.0/16 is variably subnetted, 6 subnets, 3 masksR 172.16.255.0/30 [120/10] via 192.168.255.2, 00:00:19, Serial1/0 filter R3R 172.16.255.0/24 [120/10] via 192.168.255.2, 00:00:19, serial1/0 cannot learn the filtered Route R 172.16.3.1/32 [120/10] via 192.168.255.2, 00:00:19, Serial1/0R 172.16.2.1/32 [120/10] via 192.168.255.2, 00:00:19, serial1/0C 192.168.255.0/24 is directly connected, Serial1/0C 192.168.0.0/24 is directly connected, Loopback0C 192.168.1.0/24 is directly connected, loopback192.168.1c 2.0/24 is directly connected, loopback27.
