Application Scenarios for NTP

Application Scenarios for NTP

Typical Application Scenario

On the network in Figure 12-8, SwitchA is accessing the NTP master clock server to synchronize all clocks within the network. SwitchA is configured as the unicast server, and SwitchB, SwitchC and SwitchD are configured as unicast clients. SwitchE acts as a symmetric peer of both the upstream SwitchB and downstream SwitchF.

Application in VPN

Figure 12-9 shows NTP service application. Both CE A and CE B belong to VPN 2. CE B is used as an NTP unicast server, CE A is used as an NTP unicast client, and NTP time synchronization is implementable between CE B and CE A.
