The value of vRtrInetExtTunnelFlags indicates the following -: If value of 'isOverTunnel' is set, it indicates that this tunnel is over another tunnel. A value of 'useRelativeMetric' indicates to use the relative metric info to offset IGP path cost to tunnel destination instead of absolute tunnel metric. A value of 'autoLSP' indicates if the LSP is an automatic LSP. If value of 'hasLFA' is set, then this tunnel next-hop has a loop-free alternate hop. If value of 'excludeForLdpOverRsvp' is set (applicable to RSVP tunnel only), then the MPLS LSP is not allowed to be used for LDP over RSVP. If value of 'excludeForL3VPN' is set, it indicates not to use this tunnel for L3 VPNs. If value of 'excludeForBGPShortcuts' is set, it indicates not to use this tunnel for BGP shortcuts. If value of 'excludeForBGPLabeledRoutes' is set, it indicates not to use this tunnel for BGP labeled routes. If value of 'excludeForLFA' is set, it indicates not to use this tunnel for loop-free alternate. If value of 'excludeForIGPShortcuts' is set, it indicates not to use this tunnel for IGP shortcuts. If value of 'entropyLabelCapable' is set, it indicates this tunnel is entropy capable. If value of 'isAdjacencyTunnel' is set, it indicates that this tunnel is a segment routing adjacency tunnel. If value of 'lspBfdDown' 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 'hasColor' is set, it indicates that this tunnel has color.
