How to Configure IGMP
Configuring the Device as a Member of a Group (CLI)
You can configure the device as a member of a multicast group and discover multicast reachability in a
network. If all the multicast-capable routers and multilayer devices that you administer are members of a
multicast group, pinging that group causes all of these devices to respond. The devices respond to ICMP
echo-request packets addressed to a group of which they are members. Another example is the multicast
trace-route tools provided in the software.
Performing this procedure might impact the CPU performance because the CPU will receive all data traffic
for the group address.
Caution
This procedure is optional.
