Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
Configure a network entity title (the net command) to specify the area address and the router system ID.
To establish adjacencies and establish dynamic routing, enable routing on one or more interfaces.
You can configure only one IS-IS routing process to perform Level 2 routing. A level-1-2 designation performs
Level 1 and Level 2 routing at the same time.
Related Commands
• net — configures an IS-IS network entity title (NET) for the routing process.
• is-type — assigns a type for a given area.
isis circuit-type
Configure the adjacency type on interfaces.
Syntax
isis circuit-type {level-1 | level-1-2 | level-2-only}
To return to the default values, use the no isis circuit-type command.
Parameters
level-1 You can form a Level 1 adjacency if there is at least one common area address between
this system and neighbors. You cannot form Level 2 adjacencies on this interface.
level-1-2 You can form a Level 1 and Level 2 adjacencies when the neighbor is also configured as
Level-1-2 and there is at least one common area, if not, a Level 2 adjacency is established.
This setting is the default.
level-2-only You can form a Level 2 adjacencies when other Level 2 or Level 1-2 routers and their
interfaces are configured for Level 1-2 or Level 2. Level 1 adjacencies cannot be
established on this interface.
