hi:
i know OSPF ,EIGRP and RIP are both network layer protocols .
and RIP uses UDP at port 520
EIGRP uses RTP and protocol number is 88
OSPF 's protocol number 89
both EIGRP and RTP are encapsulated into a IP packet 。
alright， if i want to use ACL to limit EIGRP or OSPF update information what port number shall i use ?
in RIP case i can put " access-list 1 deny udp any any eq 520" but how to do it with EIGRP and OSPF ??
anyone?
thanks in advance
