1262 ExtremeWare Software 7.3.0 Command Reference Guide
IGP Commands
configure isis add vlan
configure isis add vlan [<vlan name> | all] [[level-1 | level-1-2] area
<isis
area identifier> | level-2-only]
Description
Enables IS-IS routing on a routing interface.
Syntax Description
Default
By default, IS-IS is not enabled on an interface.
Usage Guidelines
A VLAN must have an IP address configured on it for it to become a routing interface.
The interface type is specified with the
level-1
,
level-1-2
, and
level-2-only
options. The interface
type determines the adjacencies that can be established on the interface. The types are:
• level-1: A level 1 adjacency can be established if there is at least one area address in common
between this system and its neighbors. Level 2 adjacencies are never established over this interface.
The area identifier of the level 1 area in which the interface is present is specified with this option.
• level-1-2: Both level 1 and level 2 adjacency is established if the neighbor’s interface is also
configured as level-1-2 and there is at least one area in common. If there is no area in common, a
level 2 adjacency is established. The area identifier of the level 1 area in which the interface is
present is specified with this option.
• level 2-only: level 2 adjacency is established if the neighbors interface is configured for level 1-2 or
level 2. Level 1 adjacencies will never be established over this interface.
Example
The following command adds vlan test as level 2 only interfaces to IS-IS:
configure isis add vlan test level-2-only
