[j-nsp] LDP breaks at MPLS/VPN Backbone

[Jack.W.Parks at alltel.com]

I don't understand your question, but here are some docs concerning BFDP
& MPLS convergence.

Thanks for your info.

BTW, does BFDP will glue together with IP routing and LDP? Since 
RFC2547 still refer to IGP eventhough there is a LDP break in the 
MPLS/VPN Backbone core router. We have this sort of experience with our 
router card which consider to be hardware failure. Of course if I'm 
running OSPF, it will choose the shortest path since the shortest path 
already LDP break, perhaps it will create blackholing in PE routing 
table.

On juniper devices and configuration, how can we escalate such a simple 
mechanism whereby it can re-route to another available paths when there 
is LDP break in the core?

thank you very much.
