Configuration Example 7: Modifying the Metric of Redistributed Routes Using a Route Map
In the first configuration example for Figure 14-3, the EIGRP routes were redistributed into OSPF with a default metric of 20. For this example, modify the configuration on Router B to change the metric of the classful routes to 100 and the metric of the classless routes to 200.
){kind=link}
Router B router ospf 1 redistribute eigrp 1 subnets route-map control-eigrp ! access-list 1 permit 6.0.0.0 0.15.255.255 access-list 1 permit 146.6.0.0 0.0.15.255 access-list 1 permit 206.6.6.0 0.0.0.15 access-list 1 permit 10.1.1.4 0.0.0.3 route-map control-eigrp permit 10 match ip address 1 set metric 200 ! route-map control-eigrp permit 20 set metric 100
Verification
Verify that the new metric has been applied to the redistributed EIGRP routes. On Router A you can look at the IP routing table and the OSPF database.
