Configuring Loopback Interfaces, Gigabit Ethernet Interfaces,
and IP Routes
To commission a basic dial access service, perform the following tasks (the CLI session for these tasks
is shown in Step 1):
• Create two loopback interfaces.
•
Bring up the Gigabit Ethernet interface.
• Add an IP route to the default gateway.
Step 1 Assign the IP addresses as in the following example, and create an IP route to the default gateway:
Router(config)# interface loopback 0
Router(config-if)# ip address 172.22.99.1 255.255.255.255
Router(config-if)# exit
Router(config)# interface loopback 1
Router(config-if)# ip address 172.22.90.1 255.255.255.0
Router(config-if)# exit
Router(config)# interface GigabitEthernet 0/0
Router(config-if)# ip address 172.28.186.55 255.255.255.240
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# ip route 0.0.0.0 0.0.0.0 172.28.186.49
In this example:
• Interface loopback 0—Identifies the VGD 1T3 voice gateway with a unique and stable IP address.
One unique IP address from a common block of addresses is assigned to each device in the IP
network. This technique makes security-filtering easy for the Network Operations Center (NOC).
One Class C subnet used for device identification can support 254 distinct devices with unique
loopback addresses.
•
Interface loopback 1—Hosts a pool of IP addresses for the remote nodes. In this way, 1 route, instead
of 254 routes, is summarized and propagated to the backbone. Pick the IP address for loopback 1
from the range of addresses that you will assign to the local address pool.
Step 2 Verify that the Gigabit Ethernet interface is up. Ping the default gateway to verify this.
Router# ping 172.28.186.49
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.28.186.49, timeout is 2 seconds:

Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/4 ms
