Configuring Mpls Vpn Time Synchronization In Client/Server Mode - 3Com S7906E Configuration Manual

Configuring MPLS VPN Time Synchronization in Client/server Mode

Network requirements
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, while CE 2 and CE 4 are devices in VPN 2.
CE 1's local clock is to be used as a reference source, with the stratum level of 1.
CE 3 is synchronized to CE 1 in the client/server mode.
At present, MPLS VPN 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.
