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.
