Configuration Example 9: Modifying the Tag Value of Redistributed Routes Using a Route Map
Modify the configuration on Router B (see Figure 14-3) to set the tag value for the classless routes to 1 and the classful routes to 2.
){kind=link}
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 10.1.1.4 0.0.0.3 route-map control-eigrp permit 10 match ip address 1 set metric 200 set tag 1 ! route-map control-eigrp permit 20 set metric 100 set metric-type type-1 set tag 2
Verification
Verify that the tags have been set on the redistributed EIGRP routes.
