Configuration procedure
1.
Assign an IP address to each interface, and make sure the switches can reach each other, as
shown in
. (Details not shown.)
2.
Configure Switch C:
# Enable the NTP service.
<SwitchC> system-view
[SwitchC] ntp-service enable
# Specify the local clock as the reference source, with 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.
