RackSwitch G8000: Application Guide
4. Configure LACP dynamic trunk group (portchannel).
RS G8000(config)# interface port 1,2
RS G8000(config-if)# lacp key 400
RS G8000(config-if)# lacp mode active
RS G8000(config-if)# exit
5. Configure a static trunk group (portchannel).
RS G8000(config)# portchannel 1 port 3,4 enable
6. Enable IGMP.
RS G8000(config)# ip igmp enable
7. Configure IGMP Relay.
RS G8000(config)# ip igmp relay vlan 2,5
RS G8000(config)# ip igmp relay mrouter 1 address 5.5.5.5 enable
RS G8000(config)# ip igmp relay mrouter 2 address 5.5.5.6 enable
RS G8000(config)# ip igmp relay enable
RS G8000(config)# vlan 2
RS G8000(config-vlan)# no flood
RS G8000(config-vlan)# exit
RS G8000(config)# vlan 5
RS G8000(config-vlan)# no flood
RS G8000(config-vlan)# exit
This section provides the steps to resolve common IGMP Relay configuration
issues. The topology described in
Multicast traffic from non-member groups reaches the hosts or the
Mrouter
• Ensure IPMC flood is disabled.
RS G8000(config)# vlan <vlan id>
RS G8000(config-vlan)# no flood
• Check the egress port's VLAN membership. The ports to which the hosts and
Mrouter are connected must be used only for VLAN 2, VLAN 3, or VLAN 5.
RS G8000(config)# show vlan
Note: To avoid such a scenario, disable IPMC flooding for all VLANs enabled on
the switches (if this is an acceptable configuration).
Figure 21 is used as an example.
