mpls atm vpi
MP-153
Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
Use this command to select an alternate range of VPI values for ATM label assignment on this interface.
The two ends of the link negotiate a range defined by the intersection of the range configured at each end.
• To configure the VPI range for an edge label switch router (edge LSR) subinterface connected to
another router or to an LSC, limit the range to four VPIs.
• For an ATM-LSR, the VPI range specified must lie within the range that was configured on the ATM
switch for the corresponding ATM switch interface.
• If the LDP neighbor is a router, the VPI range can be no larger than two. For example, you can
specify from 5 to 6 (a range of two), not 5 to 7 (a range of three). If the LDP neighbor is a switch,
the maximum VPI range is 0 to 255.
If you use the vc
i-range keyword, you must specify a VPI value.
Examples The following example shows how to create a subinterface and selects a VPI range from VPI 1 to VPI 3:
Router(config)# interface atm4/0.1 mpls
Router(config-if)# mpls ip
Router(config-if)# mpls atm vpi 1-3
The following example shows how to create a subinterface with a VPI of 240 and a VCI range between
33 and 4090:
Router(config)# interface atm4/0.1 mpls
Router(config-if)# mpls ip
Router(config-if)# mpls atm vpi 240 vci-range 33-4090
