Routing Protocols

13.1 Routing Protocols Overview

Routing protocols give the ZyWALL routing information about the network from other routers. The ZyWALL stores this routing information in the routing table it uses to make routing decisions. In turn, the ZyWALL can also use routing protocols to propagate routing information to other routers. See Section 5.5 on page 121 for related information on the RIP and OSPF screens.

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

13.1.1What You Can Do in the RIP and OSPF Screens

•Use the RIP screen (see Section 13.2 on page 288) to configure the ZyWALL to use RIP to receive and/or send routing information.

•Use the OSPF screen (see Section 13.3 on page 289) to configure general OSPF settings and manage OSPF areas.

•Use the OSPF Area Add/Edit screen (see Section 13.3.2 on page 293) to create or edit an OSPF area.

13.1.2What You Need to Know About Routing Protocols

The ZyWALL supports two standards, RIP and OSPF, for routing protocols. RIP and OSPF are compared here and discussed further in the rest of the chapter.

Table 93 RIP vs. OSPF

	RIP	OSPF
Network Size	Small (with up to 15 routers)	Large

Metric	Hop count	Bandwidth, hop count, throughput, round
		trip time and reliability.

Convergence	Slow	Fast
