Cisco OSPF Route Redistribution

Configuration Example 8: Modifying the Metric Type of Redistributed Routes Using a Route Map

In Figure 14-3, configuration example 1 for the redistribute route-map command, the EIGRP routes were redistributed into OSPF with a default metric type of 2. For this example, modify the configuration on Router B to change the metric type of the classful routes to type 1.

Router B
router ospf 1
 redistribute eigrp 1 subnets route-map control-eigrp
 network 10.1.1.0 0.0.0.3 area 0
!
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 
route-map control-eigrp permit 10
 match ip address 1
 set metric 200
!
route-map control-eigrp permit 20
 set metric 100
 set metric-type type-1

Verification

Verify that the classful EIGRP routes have been redistributed into OSPF as metric type 1 routes.
