To enable MPLS on a virtual router in Global Configuration mode, or to create an MPLS
major interface in Interface Configuration mode:
[ no ] mpls
To modify the subscriber policy for MPLS packets in Subscriber Policy Configuration
mode:
mpls { permit | deny }
no mpls
Command introduced before JunosE Release 7.1.0.
In Global Configuration mode, creates MPLS in the current virtual router. By default, MPLS
does not exist in a VR. The no mpls version removes MPLS from the VR, and additionally
removes all MPLS major interfaces, MPLS shim interfaces, MPLS load-balancing groups,
MPLS minor interfaces, and MPLS forwarding tables from the VR.
In Interface Configuration mode, creates an MPLS major interface stacked on the current
layer 2 interface, and automatically enables MPLS in the current VR if it has not already
been enabled. If the MPLS major interface already exists, no action is taken and no
message is generated. An error message is generated if you issue the command for a
layer 2 interface that does not support MPLS major interfaces. You cannot enable MPLS
on a loopback interface. The no mpls version removes the MPLS major interface.
In Subscriber Policy Configuration mode, modifies the subscriber policy for MPLS to
define whether the subscriber (client) interfaces that belong to a bridge group or to a
VPLS instance forward (permit) or filter (deny) MPLS packets. The no version restores
the default value, permit MPLS packets.
In Subscriber Policy Configuration mode, you cannot change the default subscriber policy
values for trunk (server) interfaces that belong to a bridge group or to a VPLS instance.
You also cannot change the default subscriber policy values for a VPLS virtual core
interface, which acts as a trunk interface. The VPLS virtual core interface represents all
of the MPLS tunnels from the router to the remote VPLS edge (VE) devices.
NOTE: MPLS does not exist by default and must be created, either explicitly with this
command, or implicitly with another mpls configuration command. If you create MPLS
implicitly, for example by issuing the command mpls lsp retries 10, MPLS remains
disabled until you enable it, by issuing the mpls command.
permit—Specifies that the subscriber interface associated with the bridge group or
VPLS instance forwards MPLS packets
