Configuring the Switch as a Member of a Group

You can configure the switch as a member of a multicast group and discover multicast reachability in a
network. If all the multicast-capable routers and multilayer switches that you administer are members of
a multicast group, pinging that group causes all 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
