Hi Friends..

Just for my information: I am forgetting the port on which OSPF works, I think it works on some UDP port, but I am not able to recall it. Can someone pls help me remind this..

Thanks!!

Hello Arun,

OSPF does not use UDP but IP protocol 89

in an extended ACL you can use a line like permit  ospf any any just to make an example

Hope to help

OSPF is a protocol at the IP layer so it's not TCP or UDP. It is protocol number 89.
