Syntax Description

vlan all Deletes all IS-IS VLANs.
vlan_name Specifies a single VLAN to delete.
area_name Specifies the router process from which the VLAN is deleted. If you do not specify an IS-IS area, the software deletes the VLAN from the configured IS-IS area.
ipv4 | ipv6 Specifies the IP address type for which the VLAN is deleted. If you do not specify an IP address type, the VLAN for the IPv4 address type is deleted. If the VLAN was added as IPv6, the ipv6 option must be used to remove the VLAN. If the VLAN was added as both IPv4 and IPv6, each VLAN IP address type must be deleted with a separate command.
