rip Service

The Routing Information Protocol (RIP) is a dynamic routing protocol commonly used by Internet routers. RIP messages are carried in UDP datagrams. SunScreen includes a predefined service (rip) for passing RIP packets using the udp-datagram state engine with broadcast enabled. This means that a rule allows RIP packets (including broadcasts) from source to destination.

It is usually sufficient to enable RIP in the default rule that passes RIP from the routers to all other addresses. This lets the SunScreen send and receive RIP packets without restriction. If you want to restrict RIP traffic, do not enable RIP using the default access rules; instead, define rules for RIP based on your security policy.
