[j-nsp] JUNOS MPLS vs. IOS MPLS

[Eric Van Tol]

All,
I am venturing into the fray of JUNOS/IOS MPLS interop and have some
questions.  It's my understanding that with JUNOS, LDP will only
advertise loopback routes into the inet.3 table, unless otherwise
configured.  IOS appears to announce every known route via LDP by
default.  What are best practices for handling route advertisements
through LDP in a multivendor environment?  Would one implement
restrictive filtering on the Cisco or rather configure less restrictive
filtering on the Juniper?  While I imagine this depends on one's own
design goals, maybe someone can comment on which one, to them, seems to
add less complexity.

Also, what other types of pitfalls would one expect when trying to
implement MPLS and TE in a mixed Juniper/Cisco environment?  Links would
definitely also help get me on the right track.

TIA,
