Bonding Troubleshoting

SUSE Linux Enterprise Server SLES Networking
1

Hi Guys ,

I have a opensuse server with 12 SP1 installed and configured 3 bond interface , the problem is that i’m able to access only one network out of three bonded interface to which default route is provided, others are not able to communicate for eg.

bond2 has ip range 10.10.1.0/24
bond 4 has ip range 10.10.12.0/24 – default gateway is avaliable
bond 6 has ip range 10.10.18.0/24

i’m not able to reach ip from 12 vlan to 18 vlan.

Kindly help me on this…

thanks in advance…

Before we get into this too far, is it really an openSUSE machine, vs. a
SUSE Linux Enterprise Server (SLES) machine? If the former, please use
the openSUSE forums a https://forums.opensuse.org/ which use the same
credentials as here, but which are for openSUSE. This forum is
specifically for SLES.

Also, if you are on SLES, it may be worth noting that SLES 12 SP3 is
current, and SLES 15 is in public eta, so you may want to try the latest
code, as I presume this is a new installation.

If on SLES, please post the output of the following commands:

ip link
ip a
ip r
ip neigh

You may also find it useful to share details about other systems on these
VLANs; can they reach eachother on the same VLAN? Can they reach systems
on other VLANs?

If you disable bonding, does any of this work better?

Good luck.

Hi,

just for clarification: Is the problem that a host on 10.10.12.0/24 cannot reach a host on 10.10.18.0/24, in other words, you’re trying to use the SLES server as a router?

If this is about running the SLES server as a router, please add the output to “sysctl --all|grep forwarding” to the list of helpful details :slight_smile:

Regards,
