Overview

manual. The router stores all the routing information in the form of a routing table. Routing tables contain the routes to reach a particular network, and also identify the router to which the datagram packet can be passed for this purpose. The routing tables must contain the latest routing information. Routing protocols perform the task of updating the routing tables with the latest routing information.

The primary function of a routing protocol is to exchange routing information with other routers. Routing daemons perform the task of exchanging routing information with other routers. The routing daemons supported on the HP-UX 11i v2 operating system are mrouted and gated 3.5.9.

A detailed description of the routing daemons, their conﬁguration and troubleshooting information is provided in this manual.

This chapter contains information about the following topics:

•“The mrouted Routing Daemon” on page 17
