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 Internet Control Message Protocol (ICMP) router discovery protocol
If client host systems are required to use the dynamic router, they must either run programs that can communicate using these protocols or they must specify the dynamic router as a default router.
