22.5.3.4 Verify multicast TLV’s
Assuming the multicast sender is using IGMPv3 (source IP 10.5.41.20@232.2.2.2) connect to Switch-2
off SPB bridges 8005 & 8006 with a receiver (10.5.41.10) connected to Switch-4 off SPB bridges 8007.
TLV 185 in relationship to bridges 8005 and 8006 should have the Tx bit set and also send TLV 144 with
the Tx bit set. Each multicast group should have its own unique data ISID with a value of 1600000x. The
receiver switches (8007) should have TLV 144 with the Rx bit set.
Step 1 – Verify IP multicast source, group addresses, and Tx bit set on the BEB bridge
where the multicast source is located via TLV 185
