Figure 45 Network diagram for NTP multicast mode configuration
Configuration procedure
1. Configuration on Firewall C:
# Specify the local clock as the reference source, with the stratum level of 2.
<FirewallC> system-view
[FirewallC] ntp-service refclock-master 2
# Configure Firewall C to work in the multicast server mode and send multicast messages through
GE0/1.
[FirewallC] interface gigabitethernet 0/1
[FirewallC-GigabitEthernet0/1] ntp-service multicast-server
2. Configuration on Firewall D:
# Configure Firewall D to work in the multicast client mode and receive multicast messages on GE0/1.
<FirewallD> system-view
[FirewallD] interface gigabitethernet 0/1
[FirewallD-GigabitEthernet0/1] ntp-service multicast-client
Because Firewall D and Firewall C are on the same subnet, Firewall D can receive the multicast messages
from Firewall C without being enabled with the multicast functions and can be synchronized to Firewall
C.
# View the NTP status of Firewall D after clock synchronization.
