Advertising a default route
IS-IS cannot redistribute a default route to its neighbors. This task enables IS-IS to advertise a default route
of 0.0.0.0/0 in an LSP to the same-level neighbors. Upon receiving the default route, the neighbors add
it into their routing table.
To advertise a default route:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter IS-IS IPv4
unicast address
family view or IS-IS
IPv4 unicast
topology view.
• Enter IS-IS IPv4 unicast address family view:
a. isis [ process-id ] [ vpn-instance

b. cost-style { wide | wide-compatible }
c. address-family ipv4 [ unicast ]
• Enter IS-IS IPv4 unicast topology view:
d. isis [ process-id ] [ vpn-instance
vpn-instance-name ]
e. cost-style { wide | wide-compatible }
f. address-family ipv4 [ unicast ]
g. topology topo-name tid tid
Use either method.
3. Advertise a default
route.

By default, IS-IS does not
advertise a default route.
Configuring IS-IS route redistribution
Perform this task to redistribute routes from other routing protocols into IS-IS. You can specify a cost for
redistributed routes and specify the maximum number of redistributed routes.
