Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
mpls atm vp-tunnel
Note Effective with Cisco IOS Release 12.4(20)T, the mpls atm vp-tunnel command is not available in
Cisco IOS software.
To specify an interface or a subinterface as a virtual path (VP) tunnel, use the
mpls atm vp-tunnel
command in interface configuration mode. To remove the VP tunnel from an interface or subinterface,
use the no form of this command.
mpls atm vp-tunnel vp
i [vci-range low - high]
no mpls atm vp-tunnel vp
i [vci-range low - high]
Syntax Description
Defaults If you do not specify a VCI range for the VP tunnel, the tunnel uses the default VCI range of 33-65535.
Command Modes Interface configuration (config-if)
Command History
Usage Guidelines The mpls a
tm vp-tunnel and mpls atm vpi commands are mutually exclusive.
This command is available on both extended MPLS ATM (XTagATM) interfaces and on LC-ATM
subi
nterfaces of router ATM interfaces. The command is not available on the LS1010, where all
subinterfaces are automatically VP tunnels.
It is not necessary to use the mpls at
m vp-tunnel command on an XTagATM interface in most
applications. The switch learns (through VSI interface discovery) whether the XTagATM interface is a
tunnel, the VPI value of the tunnel, and tunnel status.
Examples The following example shows how to create an MPLS subinterface VP tunnel with a VPI value of 4:
Router(config-if)# mpls atm vp-tunnel 4
vpi Virtual path identifier (VPI) value for the local end of the tunnel (0 to 4095).
vci-range l
ow - high (Optional) Range of virtual channel identifier (VCI) values the VP tunnel
can use.
Release Modification
12.0(5)T This command was introduced.
12.2(4)T This command was updated to reflect the Multiprotocol Label Switching
(
MPLS) Internet Engineering Task Force (IETF) terminology.
The vci
-range keyword was added.
The VPI range of values was extended to 4095.
12.4(20)T This command was removed.
