MPLS Commands
MPLS Commands
mpls
Syntax
[no] mpls
Context
config>router
Description
This command enables the context to configure MPLS parameters. MPLS is not enabled by default
and must be explicitely enabled (no shutdown). The shutdown command administratively disables
MPLS.
The no form of this command deletes this MPLS protocol instance; this will remove all configuration
parameters for this MPLS instance.
MPLS must be shutdown before the MPLS instance can be deleted. If MPLS is not shutdown, when
the no mpls command is executed, a warning message on the console displays indicating that MPLS
is still administratively up.
admin-group
Syntax
admin-group group-name group-value
no admin-group group-name
Context
config>router>mpls
Description
This command is used to define administrative groups or link coloring for an interface. The admin
group names can signify link colors, such as red, yellow, or green. MPLS interfaces advertise the link
colors the support. CSPF uses the information when paths are computed for constraint-based LSPs.
CSPF must be enabled in order for admin groups to be relevant.
Network resources (links) based on zones, geographic location, link location, etc., can be classified
using admin groups. MPLS interfaces must be explicitly assigned to an admin group.
Admin groups must be defined in the config>router>mpls context before they can be assigned to an
MPLS interface. The IGP communicates the information throughout the area.
Up to 32 group names can be defined in the config>router>mpls context. The admin-group names
must be identical across all routers in a single domain.
The no form of this command deletes the administrative group. All configuration information
associated with this LSP is lost.
Default
none
Parameters
group-name — Specify the name of the administrative group within a virtual router instance.
group-value — Specify the group value associated with this administrative group. This value is
