Routing protocols
Routing protocols are used between routers and routing switches to exchange reachability
information. Routers use a routing protocol to advertise available paths on which the router
can forward data. The routers use the protocol to determine the most efficient path to use.
Routers use dynamic routing protocols to avoid sending data to inoperable links and to send
data to links that generally result in the fastest transmission times.
The Avaya Ethernet Routing Switch 8800/8600 supports wire-speed IP routing of frames using
one of the following dynamic unicast IP routing protocols for path selection:
• RIPv1 (RFC 1058)
• RIPv2 (RFC 1723)
