IP protocols

Nortel Networks supports several IP services. To configure an IP network, start with the IP, ARP,

RARP, RIP, and OSPF manual and then go to the other manuals for the protocols that you want to

add. Click on any of the following for a description:

Configuring IP, ARP, RARP, RIP, and OSPF Services

IP routers need both an IP address and a physical address to transmit data. The Internet Protocol

(IP) assigns the IP address, and the Address Resolution Protocol (ARP) determines the physical

address by binding an IP address to a media access control (MAC) address. You can also configure

a Nortel Networks router as a Reverse Address Resolution Protocol (RARP) server. A RARP

server supplies clients on the same physical or logical LAN with IP addresses.

The Routing Information Protocol (RIP) is a distance-vector protocol, which means that RIP

computes distance based on the number of hops (or routers) from the source network to the target

network. For RIP, the “best” path to a destination is the shortest path (the path with the fewest

hops). Open Shortest Path First (OSPF) is a link state protocol, which means that OSPF

periodically tests the status of the physical connection to each of its neighboring routers, but allows

you to configure the cost metrics. This manual describes how to configure IP services on a Nortel

Networks router.
