Hi,

I have a FWSM with OSPF with two neighbors all in area 1, it learn inter area and external routes from one of him, my problem is that the FWSM not flood this routes to other neighbor. I make a show ospf and i see the fwsm as ASBR and i dont understand why.

I paste the output from sh run router, show ospf and show ospf neighbor commands

FWSM-USERS# sh run router
!
router ospf 1
network 10.2.89.0 255.255.255.0 area 1
network 10.2.244.0 255.255.252.0 area 1

network 10.2.252.40 255.255.255.248 area 1
