configure isis add vlan

configure isis add [vlan all | {vlan} vlan_name] area area_name {ipv4 | ipv6}


This command associates the specified VLAN interface with the specified IS-IS router process.

Syntax Description

vlan all Adds all IS-IS eligible VLANs to the router process.
vlan_name Specifies a single IS-IS eligible VLAN to be added to the router process.
area_name Identifies the router process to which the VLANs are added.
ipv4 | ipv6 Specifies the VLAN IP address type, IPv4 or IPv6, to be added. If you do not specify an IP address type, the VLAN is added for the IPv4 address type. To support both IP address types on the same VLAN, enter the command twice, using a different IP address type each time.



Usage Guidelines

An IS-IS-eligible interface is one that already has the appropriate IP address type (IPv4 or IPv6) address assigned to it. The VLAN must have an IPv4 address assigned to it if ipv4 is specified or an IPv6 address assigned to it if ipv6 is specified. In the event that a VLAN address is unconfigured, the interface is automatically removed from the IS-IS router.

VLANs are added to an IS-IS router process to form adjacencies with neighboring IS-IS routers. Hello PDUs are transmitted over these interfaces once the router process is enabled and has a system ID and area address. IP forwarding, IPv6 forwarding, or both must be enabled on the interface. If the router process operates at both L1 and L2, interfaces can be configured to form adjacencies in only a specific level.


The following command adds VLAN SJvlan with an IPv4 address type to areax:

configure isis add SJvlan area areax
