Could you guys please post the config and
how you are using the acl to filter routes.

  

Is it a distribute list out of ospf (well
theres your problem), or are you using a route-map?

  

Thanks,

  

Joe

there. I need to come up with an ACL that would only leak that route...

access-list 101 permit ip 178.2.8.248 0.0.0.0 255.255.255.248
0.0.0.0

or

Wouldn't it be

access-list 101 permit ip 0.0.0.0 255.255.255.255 255.255.255.248 0.0.0.0
