Now 3Com2 is synchronized with 3Com1. Its stratum number is 3, higher number

larger than that of 3Com1 by one.

8.4.7 Configuring Server/Client Time Synchronization for MPLS VPN

I. Network requirements

As shown in the following figure,

Two VPNs, VPN 1 and VPN 2 represented by a red curve and a blue curve

respectively, on both PE1 and PE 2.

CE 1 and CE 2 are located in VPN 1 and CE 3 and CE 4 in VPN 2.

Configure the devices to achieve these goals:

CE 2 synchronizes CE 1.

CE 1 synchronizes to the local clock source, and functions at stratum 1.

At present, NTP can provide only unitcast synchronization (in server/client or

peer-to-peer model) for MPLS VPNs.
