Originating an L2 Default Route

This feature injects a zero-cost route to 0.0.0.0 in LSPs originated by an L2 router, thereby advertising the router as the default gateway.

To enable default route origination, use the following command:
enable isis area area_name originate-default {ipv4 | ipv6}
To disable default route origination, use the following command:
disable isis area area_name originate-default {ipv4 | ipv6}
