6.7.3 Configuring IPv4 IS-IS to Advertise a Default Route
To forward all traffic in an IS-IS area through a default route, configure IS-IS on a Level-1-2
device to advertise the default route.
Context
Only the route 0.0.0.0/0 can be advertised as a default route on a Level-1-2 device. All traffic
destined for other areas is first forwarded to the Level-1-2 device.
To ensure successful traffic forwarding, external routes must be learned on the Level-1-2 device.
