MPT LSP VPI
(OPTimum cell trunk
logical port endpoints
on CBX 3500/
CBX 500 and GX 550
switches only)
Specify the VPI value for the MPT LSP root. If the switch where
the OPTimum cell trunk logical port endpoint resides is also the
root of an MPT LSP, a VPI is needed for the MPT LSP root. The
value must be an even value between 2 and 30 (for example, 4).
The default is zero (0).
The MPT LSP VPI value:
• Must be outside the VPI value ranges you configure for transit
MPT LSPs, transit point-to-point LSP connections, and virtual
UNI logical ports.
•Must not conflict with the Opt Trunk VPI value.
Transit MPT LSP VPI
Start
(OPTimum cell trunk

Specify the first VPI value in the range of VPI values for transit
MPT LSPs. The default is zero (0).
The range that you specify:
•Must not overlap the ranges that you specify for virtual UNI
logical ports and transit point-to-point LSP connections.
•Must not conflict with the Opt Trunk VPI value.
Transit MPT LSP VPI
Stop
Specify the last VPI value in the range of VPI values for transit
MPT LSPs. The default is zero (0).
The range that you specify:
•Must not overlap the ranges that you specify for virtual UNI
logical ports and transit point-to-point LSP connections.
•Must not conflict with the Opt Trunk VPI value and the
MPT LSP VPI value.
