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.
