Examples
2-15
MAC group address:0100-5e01-0101
Host port(s):Ethernet1/0/24
Vlan(id):103.
Total 0 IP Group(s).
Total 0 MAC Group(s).
Router port(s):Ethernet1/0/10
As shown above, multicast traffic can successfully flow to Host A and Host C.
2)
Configure simulated joining
Configure simulated joining on Switch B, thus to prevent the multicast switch from
considering that no multicast receiver exist on the subnet due to some reason and
removing the corresponding path from the multicast forwarding tree.
# Configure Ethernet 1/0/21 as a simulated host to join multicast group 225.1.1.1.
<SwitchB> system-view
[SwitchB] interface Vlan-interface 200
[SwitchB-Vlan-interface200] igmp host-join 225.1.1.1 port Ethernet 1/0/21
# View multicast group information that contains port information on Switch B.
<SwitchB> display mpm group
Total 1 IP Group(s).
Total 1 MAC Group(s).
Vlan(id):200.
Total 1 IP Group(s).
Total 1 MAC Group(s).
Router port(s):
IP group(s):the following ip group(s) match to one mac group.
IP group address:225.1.1.1
Host port(s):Ethernet1/0/21 Ethernet1/0/24
MAC group(s):
MAC group address:0100-5e01-0101
Host port(s):Ethernet1/0/21 Ethernet1/0/24
Vlan(id):103.
Total 0 IP Group(s).
Total 0 MAC Group(s).
Router port(s):Ethernet1/0/10
As shown above, Ethernet 1/0/21 has become a member port for multicast group
225.1.1.1.
