Configuring IP Addressing

IP Addressing Examples

The significant portions of the configurations for routers A, B, and C follow:

Router A Configuration

interface ATM0/0

ip address 10.1.0.1 255.255.0.0 ip nhrp network-id 1 map-group a

atm nsap-address 11.1111.11.111111.1111.1111.1111.1111.1111.1111.11 atm rate-queue 1 10

atm pvc 1 0 5 qsaal

router ospf 1

network 10.0.0.0 0.255.255.255 area 0

map-list a

ip 10.1.0.3 atm-nsap 33.3333.33.333333.3333.3333.3333.3333.3333.3333.33
