Configure NTP IPV6 Peer Mode

Network Requirements

• Device1, Device2, and Device3 are interconnected via their interfaces; the route is reachable.
• Device1 sets the local clock as the reference clock and the number of the layers is 3.
• Device2 is the NTP client; set Device1 to the NTP server.
• Device3 sets Device2 as the peer, Device3 is the active peer, and Device2 is the passive peer.

Configuration Steps

Step 1: Configure the IPv6 address of the interface. (omitted)

Step 2: On Device1, enable NTP IPv6, and configure the time zone as Beijing time zone, and the number of the local clock layers as 3.

Step 3: Device2 specifies Device1 as the NTP server.

#On Devie2, enable NTP IPv6, and configure the time zone as Beijing Time zone.

#Specify the IPv6 address of the NTP server as 10:1::1.

Step 4: Device3 sets Device2 as the peer.

#On Device3, enable NTP IPv6, and configure the time zone as Beijing time zone.

#Specify the IPv6 address of the NTP peer as 10:1::2.

Step 5: Check the result.

#Execute the show ntp status command on the client Device2 and view the clock synchronization status information.

The layers of Device2 clock is 4, larger than Device1 by 1, and the reference clock server address is 10:1::1, indicating that the client Device2 is already synchronized with the server Device1.

#Execute the show clock command to view the device clock on the client Device2.

#Execute the show ntp status command on the active peer Device3 and view the clock synchronization status information.

The layers of Device3 clock is 5, larger than Device2 by 1, and the reference clock server address is 10:1::2, indicating that the active peer Device3 is already synchronized with the passive peer Device2.

#Execute the show clock command to view the device clock on client Device3.
