Loopback InterfacesΒΆ

Before a loopback interface can be configured, it must be created by the interface loopback command. The loopback must be given a unique name and a positive numeric instance identifier:

tnsr(config)# interface loopback mgmtloop
tnsr(config-loopback)# instance 1
tnsr(config-loopback)# exit

This example creates a new loopback object named mgmtloop with an instance identifier of 1. Upon commit, the new interface will be available for use by TNSR. The interface will be designated loop<instance id>, in this case, loop1:

tnsr(config)# interface loop1
tnsr(config-interface)# ip address
tnsr(config-interface)# exit
