MPLS Commands

config mpls php

config mpls php [enabled | disabled]
Description
Enables and disables penultimate hop popping (PHP) at the egress LSR. When enabled, PHP is
requested on all LSPs for which the switch is the egress LSR.
Syntax Description
This command has no arguments or variables.
Default
Disabled.
Usage Guidelines
This command enables or disables whether PHP is requested by the egress LER.
When PHP is enabled, PHP is requested on all LSPs for which the switch is the egress LER.
PHP is requested by assigning the Implicit Null Label in an advertised mapping. PHP is always
performed when requested by an egress LSR (for example, when the switch is acting as an intermediate
LSR). The Implicit Null Label is always used in conjunction with routes exported by OSPF, regardless of
the PHP configuration.
This command can only be executed when MPLS is disabled.
Example
The following command enables penultimate hop popping (PHP) at the egress LSR:
config mpls php enabled
