Before You Configure IP

Before you configure IP, you should have created lower-layer interfaces over which IP traffic flows.

For example, to configure an ATM interface:

host1(config)#interface atm 1/0

host1(config-if)#atm sonet stm-1

host1(config-if)#no loopback

host1(config-if)#atm clock internal chassis

host1(config-if)#interface atm 1/0.10

host1(config-if)#atm pvc 10 0 20 aal5snap

Refer to the appropriate chapters for information on configuring a specific type of interface.

Note: If you choose to configure VRRP, it is recommended that you complete all IP address configurations before you configure VRRP. See Chapter 10, Configuring VRRP, for additional information.
