[ewg] Which IPv6 multicast group to be used for mckey ?
Hi, I am new to infiniband technology, so do not have much more exposure of it. I have installed OFED-1.5 on my machine. I was trying to run mckey application with following *two different multicast groups*. mckey -M *FF10:0:0:0:0:0:0:B* -b 10.10.10.1 (receiver) mckey -M *FF10:0:0:0:0:0:0:C* -b 10.10.10.2 -s (sender) Above both multicast groups are different still, data sent by sender received by receiver on another machine. Why it happens ? Is there any special format of IPv6 multicast groups for Infiniband ?

Hi, I did google on this and found the following link: http://www.mail-archive.com/linux-r...@vger.kernel.org/msg00953.html As per above link: RDMA CM treats AF_INET6 addresses that are either 0 or prefixed with FF1x:A01B::/32 as MGIDs 1) So, does it mean that mckey works with multicast addresses starting with FF1x:A01B only ? 2) Again, I did some testing and found that if I use multicast address * FF12:A01B:0:0:0:0:0:A* with mckey, then multicast join fails with following error: #mckey -M FF12:A01B:0:0:0:0:0:A -b fe80::202:c903:0:d1e1 mckey: starting server mckey: joining mckey: event: RDMA_CM_EVENT_MULTICAST_ERROR, error: -22 test complete return status 0 mckey fails if X bit in FF1X:A01B: , is 2. For any value of X other than 2, mckey works fine. Can anyone please tell me the reason of this ?
