4.3 Configuring IS-IS Basic Functions

4.3.1 Configuration Prerequisites
Before the task, configure an IP address for each interface, making all adjacent nodes
reachable to each other at the network layer.
4.3.2 Configuration Procedure
Follow these steps to configure IS-IS basic functions:
Enter system view
Enable IS-IS routing
process and enter its view
Assign a network entity
title (NET)
Specify a router type
Return to system view
Enter interface view
Enable an IS-IS process
on the interface
Specify network type for
the interface as P2P
Specify the adjacency
type for the interface
Note:
If a router's type is configured as Level-1 or Level-2, the type of interfaces must be the
same, which cannot be changed using the isis circuit-level command. However, an
interface's type can be changed with this command when the router's type is Level-1-2
for the establishment of a specific level adjacency.
To do... Use the command...
system-view
isis [ process-id ]
network-entity net
is-level { level-1 |
level-1-2 | level-2 }
quit
interface interface-type
interface-number
isis enable
[ process-id ]
isis circuit-type p2p
isis circuit-level
[ level-1 | level-1-2 |
level-2 ]
