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:
To do… Use the command… Remarks
Enter system view
system-view
––
Enable IS-IS routing
process and enter its view
isis [ process-id ]
Required
Not enabled by default
Assign a network entity
title (NET)
network-entity net
Required
Not assigned by default
Specify a router type
is-level { level-1 |
level-1-2 | level-2 }
Optional
The default type is level-1-2.
Return to system view
quit
––
Enter interface view
interface interface-type
interface-number
––
Enable an IS-IS process
on the interface
isis enable
[ process-id ]
Required
Disabled by default
Specify network type for
the interface as P2P
isis circuit-type p2p
Optional
By default, the network type
of an interface depends on
the physical media. The
network type of a VLAN
interface is broadcast.
Specify the adjacency
type for the interface
isis circuit-level
[ level-1 | level-1-2 |
level-2 ]
Optional
The default type is level-1-2.
 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.
