
Moving information across a network
Routing occurs at Layer 3
Routing involves two basic activities:
Determining optimal routing paths
 Transporting information groups

Background

Routing protocol RIP defined in
Request For Comments (RFC) 1058
 Internet Standard (STD)



Uses distance vectors to identify the best path to
any given destination address
RIP 2 defined 1994 in RFC 1723
