Yes, but I don't think that was what the OP was asking. I believe what he 
wanted to know was how to ensure the gluster servers talked to each other over 
his 10G interfaces.

In that regard I thought he was correct - just setup the servers via the IP 
for the interfaces. I have a multiple interface setup:

eth0:    192.168.5.0/24 : 1G
bond0:   10.10.10.0/24 : 1x1G (Bonded)

To route everything through bond0:

from 10.10.10.240
  gluster peer probe 10.10.10.241
  gluster peer probe 10.10.10.242


gluster volume create datastore1 replica 2 transport tcp \
 10.10.10.240:/mnt/gluster-brick1/datastore \
 10.10.10.241:/mnt/gluster-brick1/datastore \
 10.10.10.242:/mnt/gluster-brick1/datastore 

Net monitoring shows all gluster traffic going through bond0 as desired.

I realise this is old hat for most on the list, but I just wanted to confirm 
it for the op.
