Title : LDP IGP Synchronization for broadcast networks

RFC 5443 describes a mechanism to achieve LDP IGP Synchronization to
prevent black-holing traffic (e.g. VPN) when an interior gateway
protocol (IGP) is operational on a link but Label Distribution
Protocol (LDP) is not. If this mechanism is applied to broadcast
links that have more than one LDP/IGP peer, the metric increase
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 message changes.
