Switch 7700 Command reference Guide, v2.0

Integrated IS-IS Configuration Commands 171
By default, IS-IS does not import the routing information of other protocols.
For IS-IS, the routes discovered by other routing protocols are processed as the
routes outside the routing domain. When importing the routes of other protocols,
you can specify the routing metric of them.
When IS-IS imports routes, you can also specify to import the routes to Level-1,
Level-2 or Level-1-2.
IS-IS regards all the routes imported into the routing domain as the external
routes, which describe the way of routing outside the routing domain.
Example
Configure IS-IS to import the routing information of OSPF.

Parameter
tag: the name given to the ISIS process. The name length should be no longer
than 128 characters, and it can be 0, which means null.

■ Use the isis command to start the corresponding IS-IS routing process and
enter the ISIS view.
■ Use the undo isis command to delete the specified IS-IS routing process.
By default, IS-IS routing process is not started
For the normal operation of the IS-IS protocol, the isis command must be used to
enable the IS-IS process. Then the network-entity command is used to set a
Network Entity Title (NET) for the router. And, at last, the isis enable command is
used to enable each interface on which the IS-IS process runs. The IS-IS protocol is
actually enabled upon the completion of these configurations.
Only one IS-IS routing process can be started on one router.
Related commands: isis enable, network-entity.
Example
Start an IS-IS routing process, in which the system ID is 0000.0000.0002 and the
area ID is 01.0001.
