Configuring IS-IS GR
Enabling the Logging of Neighbor State Changes
Enabling IS-IS SNMP Trap
Binding an IS-IS Process with MIBs
Configuring IS-IS Basic Functions

Configuration Prerequisites

Before the configuration, accomplish the following tasks:
Configure the link layer protocol.
Configure an IP address for each interface, and make sure all neighboring nodes are reachable to
each other at the network layer.

Enabling IS-IS

Follow these steps to enable IS-IS:
To do...
Enter system view
Enable the IS-IS routing
process and enter its view
Assign a network entity title
(NET)
Return to system view
Enter interface view
Enable an IS-IS process on the
interface

Configuring the IS Level and Circuit Level

If only one area is available, it is recommended that:
Configure the IS level of all routers as Level-1 or Level-2 and don't configure different levels in this
case because there is no need for all routers to maintain two identical LSDBs;
Configure the IS level as Level-2 on all routers in an IP network for scalability.
For an interface of a Level-1 (or Level-2) router, the circuit level can only be Level-1 (or Level-2). For an
interface of a Level-1-2 router, the default circuit level is Level-1-2; if the router only needs to form
Level-1 (or Level-2) neighbor relationships, you can configure the circuit level for its interfaces as
Level-1 (or Level-2) to limit neighbor relationship establishment.
Follow these steps to configure the IS level and circuit level:
