Packet filter to watch RIP packets UPDATED: August 27, 1999 SUMMARY: This packet filter will show all RIP packets arriving at the PortMaster (TM). RIP is a routing protocol that uses udp/520 to transmit routing information between hosts. This is on of the protocols the PortMaster uses to learn dynamic routing information. A packet filter to watch the RIP updates can be useful in debugging routing problems.
