[f-nsp] BGP between XMRs (or from XMR to Juniper)

[David Ball]

  Thanks Andreas.  Some of the details not included in my original
post were that the XMRs will hopefully (if testing goes well) become a
part of an existing MPLS network (currently all Juniper T-series)
consisting of LDP and a full mesh of RSVP-TE LSPs.  With such a
topology it seemed as though loopback peering (LSPs are also built
btwn loopbacks) would be easiest.
  Thanks again.  And if anyone has run into stumbling blocks using
Juniper & Foundry together in an MPLS deployment, I wouldn't mind
hearing your tales.

David
