Example For Configuring Synchronization Of Ldp And An Igp - Huawei Quidway S9300 series Configuration Manual

2.16.9 Example for Configuring Synchronization of LDP and an IGP

Networking Requirements
As shown in
>P2->PE2 is an active link and the link PE1->P1->P3->PE2 is a standby link.
Configure synchronization of LDP and an IGP on the interfaces of both ends of the link between
crossing node P1 of the active link and the standby link and LDP neighboring node P2 on the
active link. After the faulty active link is recovered, the synchronization function can be used to
shorten the interval for switching the traffic from the standby link to the active link and reduce
the interruption at the millisecond level.
P and PE devices are the S9300s.
