Configuring UDP helper to convert multicast to broadcast
Network requirements
As shown in
225.1.1.1.
Configure UDP helper to convert multicast to broadcast on GigabitEthernet 2/1/1 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.

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 the UDP port 55 for UDP helper.
[RouterA] udp-helper port 55
# Configure UDP helper to convert multicast packets destined for 225.1.1.1 to broadcast packets
destined for 10.110.255.255.
[RouterA] interface gigabitethernet 2/1/1
[RouterA-GigabitEthernet2/1/1] 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.
