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.
Release Information
In Global Configuration mode, creates MPLS in the current virtual router. By default,
Description
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.
