MPLS Commands
if-num
Syntax if-num if-num
no if-num
Context config>router>mpls>interface>mpls-tp-mep
Description
This command configures the MPLS-TP interface number for the MPLS interface. This is a 32-bit
unsigned integer that is node-wide unique.
Parameters if-num — This is a 32-bit value that is unique to the node.
if-num-validation
Syntax if-num-validation {enable|disable}
no if-num-validation
Context config>router>mpls>interface>mpls-tp-mep
Description
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 3rd-party implementations may not perform
interface validation for unnumbered MPLS-TP interfaces and instead set the if-num in the dsmap
TLV to 0. If the value is 'enabled', the node performs the validation of the ingress and egress if-nums
received in the LSP echo request messages that ingress on this MPLS-interface. It validates that the
message arrives on the interface as identified by the ingress if-num, and is forwarded on the interface
as identified by the egress if-num.
If the value is 'disabled', no validation is performed for the ingress and egress if-nums received in the
LSP echo request messages that ingress on this MPLS-interface."
Default enable
Parameters
enable — Enables interface number validation.
disable — Disables interface number validation.
