The IESG has approved the following document: - 'LDP IGP Synchronization for broadcast networks' (draft-ietf-mpls-ldp-igp-sync-bcast-06.txt) as an Informational RFC This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-ldp-igp-sync-bcast/ Technical Summary LDP IGP Synchronization ([RFC5443]) 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. Working Group Summary Nothing worth noting. Document Quality This is an Informational document. This is not a protocol extension but implementations that utilize the descibed mechanism are believed to exist. The document quality is good as well as the review.
