Penultimate hop popping is requested by assigning the Implicit Null Label in an advertised mapping. Extreme's MPLS implementation always performs penultimate hop popping when requested to do so by a peer LSR. When the all VLANs option is selected, PHP is enabled on all configured VLANs that have been added to MPLS.
The following command enables penultimate hop popping (PHP) on the specified VLAN:
enable mpls php vlan vlan1
This command was first available in ExtremeXOS 11.6.
This command is available only on the platforms that support MPLS as described in the ExtremeXOS and Switch Engine 31.7 Feature License Requirements document.
