Configuration example for MPLS VPN time synchronization in
client/server mode
Network requirements
As shown in
devices in VPN 1. To synchronize the time between PE 2 and CE 1 in VPN 1, configure CE 1's local clock
as a reference source, with the stratum level 1, configure CE 1 to operate in client/server mode, and
specify VPN 1 as the target VPN.
MPLS L3VPN time synchronization can be implemented only in the unicast mode (client/server mode or
symmetric peers mode), but not in the multicast or broadcast mode.
