Configuring MPLS-TP

The if-num-validation command is used to enable or disable validation of the if-num in LSP
Trace packet against the locally configured if-num for the interface over which the LSP Trace
packet was received at the egress LER. This is because some implementations, do not perform
interface validation for unnumbered MPLS-TP interfaces and instead set the if-num in the dsmap
TLV to 0. The default is enabled.
LER Configuration for MPLS-TP
LSP and Path Configuration
MPLS-TP tunnels are configured using the mpls-tp LSP type at an LER under the LSP
configuration, using the following CLI tree:
