Command Parameters

<1-255>

Specifies the IS-IS logical interface ID.

dest-ip {A.B.C.D}

Specifies the destination IP address for the logical interface.

mlt PT_MLT<1-512>

Specifies the MLT ID that the logical interface is connected to in a Layer 2 network.

multi-area-virtual-link

Specifies the logical IS-IS interface is for a virtual NNI link for Multi-area boundary nodes.

name WORD<1-64>

Specifies the administratively-assigned name of this logical interface.

Note

If you do not assign a name when you configure virtual NNI links for Multi-Area boundary nodes for 7520 Series and 7720 Series, the system autogenerates the name and displays the name as Virtual-link-x, where x is the logical interface ID.

port {slot/port[/sub-port]}

Identifies a single slot and port. If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

primary-vid <2-4059>

Specifies the primary tunnel VLAN ID associated with this Layer 2 IS-IS logical interface.

Specifies the VLAN ID in the range of 2 to 4059. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1. By default, the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998.

src-ip <A.B.C.D> [vrf WORD<1-16>]

Configures an additional source address and optional VRF to use as the parallel tunnel for Fabric Extend.

To use an IPsec-encrypted tunnel as the parallel tunnel, ensure that you configure the same source IP address on the logical IS-IS interface and in the Fabric IPsec Gateway virtual machine.

vid {vlan-id [-vlan-id][,...]}

Specifies the list of VLANs that are associated with this logical interface.

The VLAN ID is in one of the following formats: A single VLAN ID (vlan-id), a range of VLAN IDs [(vlan-id)-(vlan-id)] or a series of VLAN IDs (vlan-id, vlan-id, vlan-id).

Default

None.

Usage Guidelines

The multi-area-virtual-link parameter only applies to 7520 Series and 7720 Series.
