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?

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
