LDP IGP Synchronization ([LDP-IGP-SYNC]) describes a mechanism 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 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.
