-> ip isis vlan 10 address-family v6
To disable IPv4/IPv6 IS-IS circuit on a particular VLAN, use the no form of the ip isis interface, as
shown:
-> no ip isis vlan 10 address-family v6
Enabling a IS-IS VLAN Circuit
Once the circuit is created, it must be enabled using the ip isis vlan admin-state command, as shown:
-> ip isis vlan 10 admin-state enable
Configuring the IS-IS Level
The Autonomous System is divided into multiple areas to reduce the control traffic and size of routing
table. To communicate within an IS-IS area, Level-1 routers are used. To communicate between areas,
Level-2 routers are used. A router can be a configured to be a Level-1 router, a Level-2 router, or both.
The level capability can be configured globally on the router or on specific interfaces. By default, the
router can operate at both levels.
To modify the level capability of the router globally, use the ip isis level-capability command as
explained in the following examples:
To configure a router as a Level-1 router, enter:
-> ip isis level-capability level-1
To configure the router as a Level-2 router, enter:
-> ip isis level-capability level-2
To configure the router to have both Level-1 and Level-2 capabilities, enter:
-> ip isis level-capability level-1/2
To modify the level capability of the router on the specified circuit, use the ip isis vlan level-capability
command as explained in the following examples:
To configure Level-1 capability on VLAN 10, enter:
-> ip isis vlan 10 level-capability level-1
To configure Level-2 capability on VLAN 10 capability, enter:
-> ip isis vlan 10 level-capability level-2
To configure both Level-1 and Level-2 capabilities on VLAN 10, enter:
-> ip isis vlan 10 level-capability level-1/2
