# Configure GigabitEthernet 2/0/2 as a static member of the multicast group 225.1.1.1.
[RouterA-GigabitEthernet2/0/2] igmp static-group 225.1.1.1
Verifying the configuration
Verify that you can capture multicast packets from Router A on Router B.
Configuring UDP helper to convert multicast to broadcast
Network requirements
As shown in Figure 79, GigabitEthernet 2/0/1 of Router B is a member of the multicast group
225.1.1.1.
Configure UDP helper to convert multicast to broadcast on GigabitEthernet 2/0/1 of Router A. This
feature enables Router A to forward multicast packets from Router B to all hosts on 10.110.0.0/16.
The multicast packets have the following details:
• UDP destination port number 55.
• Destination IP address 225.1.1.1.
Figure 79 Network diagram
Configuration procedure
Make sure Router A can reach the subnet 10.2.0.0/16.
# Enable UDP helper.
<RouterA> system-view
[RouterA] udp-helper enable
# Enable UDP helper to forward multicast packets with the UDP destination port 55.
[RouterA] udp-helper port 55
# Configure UDP helper to convert multicast packets from 225.1.1.1 to broadcast packets destined
for 10.110.255.255.
[RouterA] interface gigabitethernet 2/0/1
[RouterA-GigabitEthernet2/0/1] udp-helper multicast-map 225.1.1.1 10.110.255.255
Verifying the configuration
Verify that you can capture broadcast packets on all hosts on the network segment 10.110.0.0/16.
The broadcast packets are from Router A.
