NOTE:
In this example, Switch B must be a switch that supports IPv4 multicast routing.
Configuration procedure
1. Set the IP address for each interface, and make sure the switches can reach each other, as
shown in
2. Configure Switch C:
# Enable the NTP service.
<SwitchC> system-view
[SwitchC] ntp-service enable
# Specify the local clock as the reference source, with the stratum level 2.
[SwitchC] ntp-service refclock-master 2
# Configure Switch C to operate in IPv6 multicast server mode and send multicast messages
through VLAN-interface 2.
[SwitchC] interface vlan-interface 2
[SwitchC-Vlan-interface2] ntp-service ipv6 multicast-server ff24::1
3. Configure Switch D:
# Enable the NTP service.
<SwitchD> system-view
[SwitchD] ntp-service enable
# Configure Switch D to operate in IPv6 multicast client mode and receive multicast messages
on VLAN-interface 2.
[SwitchD] interface vlan-interface 2
[SwitchD-Vlan-interface2] ntp-service ipv6 multicast-client ff24::1
4. Verify the configuration:
Switch D and Switch C are on the same subnet, so Switch D can do the following:
Receive the IPv6 multicast messages from Switch C without being enabled with the IPv6
multicast functions.
Synchronize to Switch C.
# Verify that Switch D has synchronized to Switch C, and the clock stratum level is 3 on Switch
D and 2 on Switch C.
[SwitchD-Vlan-interface2] display ntp-service status
Clock status: synchronized
