Enable IS-IS

The IS-IS service has a master enable/disable toggle that must be set before IS-IS will operate. Enable IS-IS using the enable command in config-isis-ospf mode:

tnsr(config)# route dynamic isis
tnsr(config-frr-isis)# enable

To disable the service, use no enable or disable.

The IS-IS service is managed as described in Service Control.
