| Description | 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. |
