Symptoms
Standby cluster member in ClusterXL High Availability Bridge mode is passing/forwarding IGMP traffic.
Cluster debug ('fw ctl debug -m cluster + select') on both members shows: FW-1: fwha_select_ip_packet: IGMP Packet passed to OS (member 0).;
FW-1: fwha_select_ip_packet: IGMP Packet passed to OS (member 1).;
Cause
IGMP is being forwarded to the OS in order to be handled by RouteD daemon. Since in Bridge mode the RouteD daemon is not used, the IGMP is not dropped by Standby member. As a result, both members forward the traffic.
