Configure IP interfaces for the SSR if you want to use the SSR for IP-based unicast or 
multicast traffic. This chapter

•

provides an overview of IP.

•

describes creating and modifying IP interfaces.

•

indicates what you need to do after you create IP interfaces.

•

discusses configuring the SSR for VRRP.

The Internet Protocol (IP) is a Layer-3 (network) protocol that provides addressing and 
control information the SSR needs to route data packets in a network. The SSR supports IP 
routing as specified in RFC 1812. (IP is often referred to as TCP/IP.)

Acting as a connectionless packet-delivery service, IP does not provide a dedicated link 
between computers. Instead, IP provides dynamic routing by using best-effort delivery to 
route packets through any number of paths in the network. This dynamic routing is 
enabled through the routing table IP maintains. This table consists of pairs of destination 
addresses and next hop addresses. IP uses the table to determine that to get to a specific 
network address its next hop should be to a particular interface.

Suppose you have two hosts connected together with a router as shown in the following 
figure. Host A, which is on network 10.0.0.0, has an IP address of 10.0.0.2. Host B, which is
