OSPF route-map not working

I have the following ospf configuration:

router ospf 1

network 172.16.11.0 0.0.0.7 area 0

distribute-list route-map TEST in

access-list 1 permit 172.16.11.1

access-list 2 permit 172.16.11.2

!

route-map TEST permit 10

match ip next-hop 1

set metric +20

!

route-map TEST permit 20

match ip next-hop 2

set metric +10

However, the match statement works as expected but the set metric +10 does nothing!

Why can I not adjust received metrics?

Re: OSPF route-map not working

The distribute-list command is used to prevent Open Shortest Path First (OSPF) routes from being added to the routing table. It can't really used to adjust metrics.

Re: OSPF route-map not working

Hello Dave,

>> Why can I not adjust received metrics?

OSPF is a link state protocol the metric is computed building a SPF tree rooted at the local node and adding link costs on the path and the cost parameters in the LSA data structure that describes the route.

The kind of action you are trying is compatible with a distance vector protocol behavior like RIP.

Hope to help

Giuseppe
