When you finish setting these attributes, continue with the section, “Completing the
Logical Port Configuration” on page 4-52.
MPT LSP VPI Specify the VPI value for the multipoint-to-point (MPT) label
switched path (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. It must also not conflict
with the value specified in the Opt Trunk VPI field.
Transit MPT LSP
VPI Start
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. It must also not conflict with the values specified in the
Opt Trunk VPI and MPT LSP VPI fields.
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. It must also not conflict with the values specified in the
Opt Trunk VPI and MPT LSP VPI fields.
Transit Pt-Pt LSP
VPI Start
Specify the first VPI value in the range of VPI values for transit
point-to-point LSP connections. If you enter zero (0), the transit
point-to-point LSP connection is disabled.
The range that you specify must not overlap the ranges that you
specify for virtual UNI logical ports and transit MPT LSPs. It must
also not conflict with the values specified in the Opt Trunk VPI and
MPT LSP VPI fields.
Transit Pt-Pt LSP
VPI Stop
Specify the last VPI value in the range of VPI values for transit
point-to-point LSP connections. If you enter zero (0), the transit
point-to-point LSP connection is disabled.
The range that you specify must not overlap the ranges that you
specify for virtual UNI logical ports and transit MPT LSPs. It must
also not conflict with the values specified in the Opt Trunk VPI and
MPT LSP VPI fields.
