I've two NICs bonded together as bond0. I can do traceroutes using
bond0 as the interface. But when I configure a virtual IP over bond0
(virtual i/f bond0:0), I cannot do traceroutes using bond0:0
Its RHEL AS 3.0 (update 5) btw..
Any ideas?
[root@plinux12 root]# ifconfig bond0
bond0 Link encap:Ethernet HWaddr 00:0E:0C:6D:60:A9
inet addr:A.B.C.30 Bcast:A.B.C.255 Mask:255.255.255.0
UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1
RX packets:204934735 errors:0 dropped:0 overruns:0 frame:0
TX packets:157330806 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:3717085046 (3544.8 Mb) TX bytes:1706013707 (1626.9 Mb)
Traceroutes using bond0 to any other hosts works:
[root@plinux12 root]# traceroute plinux11 -i bond0
traceroute to plinux11.net.bms.com (A.B.C.29), 30 hops max, 38 byte packets
1 plinux11 (A.B.C.29) 0.305 ms 0.190 ms 0.238 ms
Now, here the virtual nic bond0:0.
[root@plinux12 root]# ifconfig bond0:0
bond0:0 Link encap:Ethernet HWaddr 00:0E:0C:6D:60:A9
inet addr:A.B.C.9 Bcast:A.B.C.255 Mask:255.255.255.0
UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1
[root@plinux12 root]# traceroute plinux11 -i bond0:0
setsockopt: No such device
unable to bind to device:
bond0:0 <----------- It fails.
bond0:0 -- unable to bind..????
I am able to ping bond0:0 from other hosts.
Is there a limitation that, bonded nic is already a virtual interface
(well kind of), and one cannot create a virtual nic over a bonded interface?
Many thanks in advance.
