Admin group support on facility bypass backup LSPs provides for the inclusion of the LSP primary path admin-group constraints in the computation of an FRR facility bypass backup LSP to protect the primary LSP path. Admin group constraints are honored by all nodes in the LSP path both for primary and FRR backup LSPs.
This feature is supported on primary paths of an RSVP point-to-point LSP in both intra-area and inter-area TE where applicable.
This feature is not supported on one-to-one detour backup LSPs.
