mplsL3VpnVrfRteXCPointer
mpls L3 Vpn Vrf Rte XC Pointer
Index into mplsXCTable that identifies which cross- connect entry is associated with this VRF route entry by containing the mplsXCIndex of that cross-connect entry. The string containing the single-octet 0x00 indicates that a label stack is not associated with this route entry. This can be the case because the label bindings have not yet been established, or because some change in the agent has removed them. When the label stack associated with this VRF route is created, it MUST establish the associated cross-connect entry in the mplsXCTable and then set that index to the value of this object. Changes to the cross-connect object in the mplsXCTable MUST automatically be reflected in the value of this object. If this object represents a static routing entry, then the manager must ensure that this entry is maintained consistently in the corresponding mplsXCTable as well.
