James,

I am facing 3 issues:

ISSUE #1:
=============================

I tried the ldp_zebra port and the application core dumps when I configure
mpls ip at the router level (CLI) like the examples where showing.

CLI VIEW:
---------------
ldpd# config t
ldpd(config)# mpls ip
Connection closed by foreign host.
