3.24.2.1.2
mpls
Syntax [no] mpls
Context config>router
Description This command creates the MPLS protocol instance and enables MPLS configuration. The
MPLS protocol instance is not created by default, but once it is created, a no shutdown
command is not required since MPLS is enabled automatically. The shutdown command
administratively disables MPLS.
The no form of this command deletes this MPLS protocol instance and all configuration
parameters for this MPLS instance.
MPLS must be shut down and all SDP bindings to LSPs removed before the MPLS instance
can be deleted. If MPLS is not shut down, when the no mpls command is executed, a
warning message on the console indicates that MPLS is still administratively up.
admin-group-frr
Syntax [no] admin-group-frr
Context config>router>mpls
Description This command enables the use of admin-group constraints in the association of a manual or
dynamic bypass LSP with the primary LSP path at a Point-of-Local Repair (PLR) node.
When this command is enabled, each PLR node reads the admin-group constraints in the
FAST_REROUTE object in the PATH message of the LSP primary path. If the
FAST_REROUTE object is not included in the PATH message, the PLR reads the admin-
group constraints from the SESSION_ATTRIBUTE object in the PATH message.
If the PLR is also the ingress LER for the LSP primary path, it only uses the admin-group
constraint from the LSP and/or path level configurations.
The PLR node then uses the admin-group constraints along with other constraints, such as
hop-limit and SRLG, to select a manual or dynamic bypass LSP among those that are already
in use.
If none of the manual or dynamic bypass LSPs satisfies the admin-group constraints and/or
the other constraints, the PLR node will request CSPF for a path that merges the closest to
the protected link or node and includes or excludes the specified admin-group IDs.
Changes to this command (enabling or disabling) will apply only to new attempts to find a
valid bypass.
