Configure IS-IS Route Generation

Configuration Condition

Before configuring the IS-IS route generation, first complete the following tasks:

• Configure the IP address for the interface to enable the neighboring nodes to be reachable at the network layer.
• Enable the IS-IS protocol.

Configure IS-IS Default Route

The Level-2 area of the IS-IS protocol cannot generate the default route during operating. You can configure to add a default route with the destination IP address as 0.0.0.0/0 in the Level-2 LSP and release it. When other areas of the same level in the intermediate system receive the route information, a default route will be added in the routing table.

Table 9-6: Configure the IS-IS default route

Configure IS-IS Routing Redistribution

The routing redistribution can be used to introduce the routing information of other routing protocols to the IS-IS protocol. This enables the interconnection between the autonomous system of the IS-IS protocol and the autonomous system of other routing protocols or the routing area. When the external routing is introduced, the routing introduction policy and the routing layer attribute after introduction are specified.
