Use the ipv6 default-route-advertise command to generate a Level-1 or 
Level-2 IPv6 IS-IS default route.

Use the undo ipv6 default-route-advertise command to disable generating a 
default route.

No IPv6 IS-IS default route is generated by default.

With a routing policy, you can configure IPv6 IS-IS to generate the default route 
that must match the routing policy. You can use the apply isis level-1 command 
in routing policy view to generate a default route in L1 LSPs, or use the apply isis 
level-2 command in routing policy view to generate a default route in L2 LSPs, 
and use the apply isis level-1-2 in routing policy view to generate a default route 
in L1 and L2 LSPs respectively.

Refer to “apply isis” on page 1191 for information about the apply isis 
command.

# Configure the router to generate a default route in Level-2 LSPs.
