             A value of 'use-relative-metric' indicates to use the relative metric info
             to offset IGP path cost to tunnel destination instead of absolute tunnel
             metric.

             A value of 'auto-lsp' indicates if the LSP is an automatic LSP.

             If value of 'has-lfa' is set, then this tunnel next-hop has a loop-free
             alternate hop.

             If value of 'exclude-for-ldp-over-rsvp' is set (applicable to RSVP tunnel
             only), then the MPLS LSP is not allowed to be used for LDP over RSVP.

             If value of 'exclude-for-l3-vpn' is set, it indicates not to use this
             tunnel for L3 VPNs.

             If value of 'exclude-for-bgp-shortcuts' is set, it indicates not to use
             this tunnel for BGP shortcuts.

             If value of 'exclude-for-bgp-labeled-routes' is set, it indicates not to use
             this tunnel for BGP labeled routes.

             If value of 'exclude-for-lfa' is set, it indicates not to use this tunnel
             for loop-free alternate.

             If value of 'exclude-for-igp-shortcuts' is set, it indicates not to use
             this tunnel for IGP shortcuts.

             If value of 'entropy-label-capable' is set, it indicates this tunnel is
             entropy capable.

             If value of 'is-adjacency-tunnel' is set, it indicates that this tunnel is
             a segment-routing adjacency tunnel.

             If value of 'lsp-bfd-down' is set, it indicates that BFD is down on this
             tunnel/FEC and that it will not be used as a transport tunnel. If this
             value is not set, then LSP-BFD is not configured on the tunnel/FEC, or
             LSP-BFD is configured and the BFD state is up.

             If value of 'prefer-transport-frr' is set, it indicates that this tunnel
             will defer to using any underlying transport tunnel's FRR.

             If value of 'allow-sr-over-srte' is set, it indicates that SR over SR-TE
             is allowed for this tunnel.

             If value of 'encrypted-tunnel' is set, it indicates that this is an
