This chapter describes how to configure the Netra server as a router.
Routing is the mechanism by which systems on different networks can
communicate with each other. Each network usually has at least one system
called a router. A router is a system that is connected to multiple networks; it
maintains information that defines routes between host systems and networks.
Netra System Routers
The Netra system can be configured as one of the following:
•
A dynamic router
•
A static router
•
Not a router
Dynamic Router
A dynamic router relies on information broadcast from other routers to update
its routes and reflect changes in the network topology. It also broadcasts this
information to other dynamic routers.
Dynamic routers are typically required when systems act as gateways between
networks or within large networks where route information is constantly
changing. The Netra server supports the following dynamic routing protocols:
•
The Xerox NS Routing Information Protocol (RIP)
•
The ICMP router discovery protocol
