Class Hierarchy :
This class represents state data.
This table shows detour setup constraints
The fast reroute log table records fast reroute events such as protected links going up or down or the FRR feature kicking in
The mplsFrrFacRouteDBTable provides information about the fast reroute database. Each entry belongs to an interface, protecting backup tunnel and protected tunnel. MPLS interfaces defined on this node are protected by backup tunnels and are indexed by mplsFrrFacRouteProtectedIndex. Backup tunnels defined to protect the tunnels traversing an interface, and are indexed by mplsFrrFacRouteProtectingTunIndex. Note that the tunnel instance index is not required, since it is implied to be 0, which indicates the tunnel head interface for the protecting tunnel. The protecting tunnel is defined to exist on the PLR in the FRR specification. Protected tunnels are the LSPs that traverse the protected link. These LSPs are uniquely identified by mplsFrrFacRouteProtectedTunIndex, mplsFrrFacRouteProtectedTunInstance, mplsFrrFacRouteProtectedTunIngressLSRId, and mplsFrrFacRouteProtectedTunEgressLSRId
