Routing protocols give the ISG50 routing information about the network from other routers. The

ISG50 stores this routing information in the routing table it uses to make routing decisions. In turn,

the ISG50 can also use routing protocols to propagate routing information to other routers. See

Section 6.7 on page 103

Routing protocols are usually only used in networks using multiple routers like campuses or large

enterprises.

• Use the RIP screen (see

and/or send routing information.

• Use the OSPF screen (see

• Use the OSPF Area Add/Edit screen (see

The ISG50 supports two standards, RIP and OSPF, for routing protocols. RIP and OSPF are

compared here and discussed further in the rest of the chapter.

RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a device to exchange routing

information with other routers. RIP is a vector-space routing protocol, and, like most such
