Title : LDP extension for AII reachability

The dynamic End-to-End Multisegment pseudowire setup requires PEs to
maintain a pseudowire routing table when using FEC129. There is
therefore a requirement for automatic Attachment Individual
Identifiers discovery. Two mechanisms already exist, a BGP based
solution and an IGP based one. Here we define a third solution
relying on LDP. It allows for automatic discovery of the Attachment
Individual Identifiers provsionned on a PE when this node does not run BGP or IGP. The mechanism described here only runs on the
T-LDP (Targeted LDP) session between the T-PE and S-PE, but not on
any other LDP session which may exist for the tunnels. The T-PE
advertises its locally attached AIIs only for the S-PE to build its
PW routing table (the S-PE does not propagate this information
further via this mechanism).
The mechanism described here is intended to complement other
existing autodiscovery and routing mechanisms already described
with BGP and OSPF.
