NTP symmetric peers mode configuration example

Network requirements

As shown in

Figure 51

, the local clock of SecPath A is to be configured as a reference source, with the

stratum level of 2. SecPath B operates in client mode and SecPath A is to be used as the NTP server of

SecPath B. SecPath C operates in symmetric-active mode and SecPath B acts as the peer of SecPath C.
