	Title		: LDP IGP Synchronization for broadcast networks

   [LDP-IGP-SYNC] describes a mechanism to prevent black-holing traffic 
   (e.g. VPN) when IGP is operational on a link but LDP is not. If this 
   mechanism is applied to broadcast links that have more than one 
   LDP/IGP peer, the cost-out procedure can only be applied to the link 
   as a whole but not an individual peer. When a new LDP peer comes up 
   on a broadcast network, this can result in loss of traffic through 
   other established peers on that network. This document describes a 
   mechanism to address that use-case without dropping traffic. The 
   mechanism does not introduce any protocol changes.
