Tom -
Just a heads up that I can reproduce this in my environment:
[root@server ~]# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008)
Bonding Mode: load balancing (round-robin) MII Status: down MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0
[root@server network-scripts]# cat /proc/net/bonding/bond2 Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008)
Bonding Mode: load balancing (round-robin) MII Status: up MII Polling Interval (ms): 0 Up Delay (ms): 0 Down Delay (ms): 0
Slave Interface: eth0 MII Status: up Link Failure Count: 0 Permanent HW addr: XXXXXXXXXXXX
Slave Interface: eth1 MII Status: up Link Failure Count: 0 Permanent HW addr: XXXXXXXXXXXX

I'm running into a situation where a bogus bonded interface named "bond0" is being created, in addition to the desired "bond2" interface. Can anyone confirm this? Anyone know why it's happening or what I do to get rid of it? I wanted to start my numbering scheme at 2 instead of 0, which I didn't think would be a problem.
As you can see, I have no reference to bond0 in any of my configs:
# grep bond /etc/modprobe.conf alias bond2 bonding
# ifconfig -a | grep bond bond0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 bond2 Link encap:Ethernet HWaddr XXXXXXXXXXXXXXXXX
# cat /etc/sysconfig/network-scripts/ifcfg-bond2 DEVICE=bond2 IPADDR=XXXXXXXXX NETMASK=XXXXXXXX NETWORK=XXXXXXXXX USERCTL=no BOOTPROTO=none ONBOOT=yes BONDING_OPTS="mode=1 miimon=100"
# cat /etc/sysconfig/network-scripts/ifcfg-eth2 DEVICE=eth2 MASTER=bond2 SLAVE=yes HWADDR=XXXXXXXXXXXX ONBOOT=yes BOOTPROTO=none USERCTL=no
# cat /etc/sysconfig/network-scripts/ifcfg-eth3 DEVICE=eth3 MASTER=bond2 SLAVE=yes HWADDR=XXXXXXXXXX ONBOOT=yes BOOTPROTO=none USERCTL=no
The bond0 interface isn't doing any harm, as far as I can tell, except adding bogus data to ifconfig output and extra, useless charts in our system performance monitoring tools.
# cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.4.0 (October 7, 2008)

Bonding Mode: fault-tolerance (active-backup) Primary Slave: None Currently Active Slave: eth2 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0

Any help is appreciated.
