OSPF and mananging static route

Hi all,

I'm in stuck with a very easy question. Topic is how ospf is managing static route. I hav e a static route in a router but it is not able to announce it. Following the scenario  (very easy its only for learning scope)

I have this topology:

OSPF is perfectly running between R3 and R2, only the static route on R2 is not announc ed properly.

R3--------------R2--------------R1

R3 and R2 are running ospf, process 200 area 0

R1 is not running any routing protocol.

The network between R2 and R1 is: 25.25.25.0/24.

The network between R2 and R3 is: 192.168.1.0

Attached to R1 there is a network:55.55.55.0/24.

On R2 I created a static route to achieve the network 55.55.55.0/24:

ip route 55.55.55.0 255.255.255.0 25.25.25.1.

The router R2 has this partial configuration:

router ospf 200

log-adjacency-changes

network 192.168.1.34 0.0.0.0 area 0

network 25.25.25.0 0.0.0.255 area 0

Why R2 is not announce the network 55.55.55.0 to its neighbour R3?

Many thanks!!!

Hi Giuseppe,

So far I realized that in my topology R2 is an ASBR so you right, I need to redistribuite the static route.

Thanks.
