Ntp Configuration Task List; Configuring The Operation Modes Of Ntp - 3Com S7906E Configuration Manual

The NTP client on a PE can be synchronized to the NTP server on another PE through a
designated VPN instance.
The NTP server on a PE can synchronize the NTP clients on multiple CEs in different VPNs.
A CE is a device that has an interface directly connecting to the service provider (SP). A CE is not
"aware of" the presence of the VPN.
A PE is a device directly connecting to CEs. In an MPLS network, all events related to VPN
processing occur on the PE.
