ip address (loopback)

Configure a circuitless IP interface (CLIP) when you want to provide a virtual interface that is not associated with a physical port. You can use a CLIP interface to provide uninterrupted connectivity to your switch.

Syntax

ip address <1-256> {A.B.C.D/X}
ip address <1-256> {A.B.C.D/X} [vrf WORD<1-16>]
ip address <1-256> {A.B.C.D/X} [name WORD<0-64>]
ip address <1-256> {A.B.C.D} {A.B.C.D}
ip address {A.B.C.D/X}
ip address {A.B.C.D/X} [vrf WORD<1-16>]
ip address {A.B.C.D/X} [name WORD<0-64>]
ip address {A.B.C.D/X} multi-area-virtual-link <home | remote> [name WORD<0-64>]
ip address {A.B.C.D} {A.B.C.D}
ip address {A.B.C.D} {A.B.C.D} vrf WORD<1-16>
ip address {A.B.C.D} {A.B.C.D} name WORD<0-64>
ip address {A.B.C.D} {A.B.C.D} multi-area-virtual-link <home | remote> [name WORD<0-64>]
no ip address <1-256> {A.B.C.D}
no ip address <1-256> {A.B.C.D} vrf WORD<1-16>
no ip address <1-256> {A.B.C.D} name WORD<0-64>
no ip address {A.B.C.D}
no ip address {A.B.C.D} vrf WORD<1-16>
no ip address {A.B.C.D} name WORD<0-64>

Command Parameters

[vrf WORD<1-16>]: Specifies an associated VRF by name.
{A.B.C.D/X}: Specifies the IP address and subnet mask.
{A.B.C.D}: Specifies the IP address.
<1-256>: Specifies the interface identification number for the circuitless IP (CLIP).

multi-area-virtual-link: Specifies that the source IP address is used for a Mulit-area virtual NNI link.
<home | remote>: Specifies the transport area for the Multi-area virtual NNI link.

name WORD<0-64>: Specifies a name associated with the IP address.

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.

Default

None
