Configuration procedure

In this example, Switch B must support IPv4 multicast routing.

1.

Set the IP address for each interface as shown in

Figure 14

. (Details not shown.)

2.

Configure Switch C:
# Enable the NTP service.

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.

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:
# Because Switch D and Switch C are on the same subnet, Switch D can receive the IPv6 multicast
messages from Switch C without being enabled with the IPv6 multicast functions and can be

synchronized to Switch C. Display the NTP status of Switch D after clock synchronization.

[SwitchD-Vlan-interface2] display ntp-service status

Clock status: synchronized

Clock stratum: 3

System peer: 3000::2

Local mode: bclient
