Enabling Is-Is; Configuring The Is Level And Circuit Level - HP 3600 v2 series Configuration Manual

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, HP recommends you to perform the following operations:
Configure the IS level of all routers as Level- 1 or Level-2 rather than different levels because the
•
routers do not need 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, then 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:
To do...
Enter system view
Enter IS-IS view
Specify the IS level
Return to system view
Enter interface view
Specify the circuit level
Use the command...
system-view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
network-entity net
quit
interface interface-type
interface-number
isis enable [ process-id ]
Use the command...
system-view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
is-level { level-1 | level-1-2 |
level-2 }
quit
interface interface-type
interface-number
isis circuit-level [ level-1 | level-1-2
| level-2 ]
