configure isis circuit-type

configure isis [vlan all | {vlan} vlan_name] circuit-type level [1 | 2 | both-1-and-2]

Description

This command configures the circuit type level for one or all IS-IS VLANs.

Syntax Description

vlan all Applies the selected circuit type to all IS-IS VLANs.
vlan_name Specifies a single VLAN to which the circuit type configuration applies.
level [1 | 2 | both-1-and-2] Sets the circuit type level to level 1, level 2, or to both level 1 and level 2.

Default

Both-1-and-2.

Usage Guidelines

Hello PDUs are only sent on the specified level for the selected VLANs. This can be useful for level 1/level 2 routers that are neighbors.

Note that for per-level VLAN configurable parameters L1 and L1/L2, point-to-point interfaces use the level 1 parameters, and L2-only point-to-point interfaces use the L2 parameters.

Example

The following command configures all IS-IS VLANs to use circuit type level 1:

configure isis vlan all circuit-type level 1
