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
?
Thanks in advance,
Vivek

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 is
received
by receiver on another machine. Why it happens ?
Is there any special format of IPv6 multicast groups for Infiniband ?
Thanks in advance,
Vivek.
