Step 3 Configure the interfaces, as shown in the following examples.
Note
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface pos0/2/0/1
RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.0.0.0
RP/0/RP0/CPU0:router(config-if)# no shutdown
RP/0/RP0/CPU0:router(config-if)# commit
RP/0/RP0/CPU0:router(config-if)# end
RP/0/RP0/CPU0:router#
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface pos0/2/0/2
RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.1.1.2 255.255.0.0
RP/0/RP0/CPU0:router(config-if)# no shutdown
RP/0/RP0/CPU0:router(config-if)# end
