[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [FW-1] multicast between cluster members
Hi Wen, we have been recognizing the same behaviour. Multicast IP packets originating from the gateway when cpstart is performed. We had a service request at CP secure trak. Here is the answer by CP: "After we tested this problem here, here is what we find out. In fact ClusterXL, beginning with FP3 and also in Application Intelligence, will send IGMP v2 membership packets from all cluster members. The behavior is as follows: The firewall will usually send on IGMP leave packet to 224.0.0.2 for the multicast group that had previously joined. The multicast address generated by each cluster member is based on the last three octets of the gateway cluster IP address. The firewall will send 3 IGMP membership packets to the other members in the gateway cluster. This mechanism is hardcoded and cannot be disabled. It is not recommended to block these packets on the firewall as this allows ClusterXL to know what cluster members have come up or gone down via cphastop/cphastart."
