admin-group-frr
Syntax [no] admin-group-frr
Context config>router>mpls
Description This command enables the use of the 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, then the PLR will read 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, then it just 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 among those that are already in use.
If none of the manual or dynamic bypass LSP 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 that includes or excludes the specified admin-group IDs.
If the user changes the configuration of the above command, it will not have any effect on existing
bypass associations. The change will only apply to new attempts to find a valid bypass.
The no form of this command disables the use of administrative group constraints on a FRR backup
LSP at a PLR node.
Default no frr-admin-group
frr-object
Syntax [no] frr-object
Context config>router>mpls
Description This command specifies whether fast reroute for LSPs using the facility bypass method is signalled
with or without the fast reroute object using the one-to-one keyword. The value is ignored if fast
reroute is disabled for the LSP or if the LSP is using one-to-one Backup.
Default frr-object — The value is by default inherited by all LSPs.
