Hi,
 Thanks,

 But 'nexthop' as seen by the routing table is
 immediately connected and is dynamic and could 
 change as dictated by the routing protocol. This
 cannot possibly be configured at the remote peer.
 The LDP peer is 'remote'. Also this doesn't explain
 the FEC as indicated by martini draft...

 I feel the 'nexthop' needs to be qualified, for e.g
 if this is  BGP nexthop it is actually multiple hops
 away and the FEC's immediate nexthop should not be
 considered but (E)BGP nexthop...

 Also consider the DU case where unsolicited bindings
 come in and the local LSR needs to decide which 
 binding is in effect...
Regards,
vishal.
