Configuration example for MPLS VPN time
synchronization in client/server mode
Network requirements
As shown in Figure 38 , two VPNs are present on PE 1 and PE 2: VPN 1 and VPN 2. CE 1 and CE 3 are
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 2, configure CE 1 to operate in client/server mode, and
specify VPN 1 as the target VPN.
