If the LDP peer is reachable, the IGP is informed to wait for LDP and to announce max-metric. If the LDP peer is not reachable (f.e. after a router reload), the IGP will establish an adjacency to learn the Loopback IP. Once this has happened, the peer is reachable and LDP-IGP sync kicks in. eventhalle dauphin

The LDP session goes down. LDP is not configured on an interface. Refer to the document on Understanding LDP-IGP Synchronization WebThis may cause LDP to de-program the LFA next-hop from the FEC and blackhole traffic. In order to avoid this situation, it is recommended to enable IGP-LDP synchronization on the LDP interface. When the SPF computation determines there is more than one primary next-hop for a prefix, it will not program any LFA next-hop in RTM. eventhalle hagenWeb1 feb. 2016 · IGP-LDP synchronization and LDP session protection are tools for protecting against such events.
