2. Use the ip address command in Interface Configuration mode to define an IP
address for the loopback interface, as shown below:
MOT(config-if)#ip address <A.B.C.D> <net-mask>
where:
A.B.C.D is the IP address of the BSR interface designated for the loopback
interface.
net-mask is the subnetwork mask of the IP network, on which the interface is
associated.
3. To optionally configure a secondary IP address for the loopback interface use the
ip address secondary command, in Interface Configuration mode, as shown
below:
MOT(config-if)#ip address <A.B.C.D> <net-mask> secondary
where:
A.B.C.D is the secondary IP address of the BSR interface.
net-mask is the subnetwork mask of the IP network, on which the interface is
associated.
secondary optionally designates the IP address as a secondary ip address.To
specify additional secondary IP addresses include the keyword secondary
after the IP address and subnet mask.
4. To verify the loopback interface configuration, use the show interface loopback
command in Interface configuration mode, as shown below:
MOT(config-if)#show interface loopback <n>
where:
n is the number of the loopback interface from 1 to 16
