14.1 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
page 107 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.

14.1.1 What You Can Do in this Chapter

• Use the RIP screen (see
use RIP to receive and/or send routing information.
• Use the OSPF screen (see
settings and manage OSPF areas.
• Use the OSPF Area Add/Edit screen (see
create or edit an OSPF area.

14.1.2 What You Need to Know

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.
