mpls Tunnel AR Hop Ip Addr
The Tunnel Hop Address for this tunnel hop. The type of this address is determined by the value of the corresponding mplsTunnelARHopAddrType. If mplsTunnelARHopAddrType is set to unnum(4), then this value contains the LSR Router ID of the unnumbered interface. Otherwise the agent SHOULD set this object to the zero-length string and the manager should ignore this object.
