With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
mplsTunnelHopAddrUnnum
mpls Tunnel Hop Addr Unnum
If mplsTunnelHopAddrType is set to unnum(4), then this value will contain the interface identifier of the unnumbered interface for this hop. This object should be used in conjunction with mplsTunnelHopIpAddress which would contain the LSR Router ID in this case. Otherwise the agent should set this object to zero-length string and the manager should ignore this.
