[c-nsp] mpls ip creating traffic disturbance(s)

>So ospf summary-address statements will break MPLS?
In MPLS core all that matters is the reachability from one PE loopback to
other PE loopback (/32 prefixes), actually nothing else needs to be
advertised by OSPF
So if all of a sudden you'll replace the /32 loopback prefix with a summary
prefix you'll basically break the label switched path between the PEs
