Re: ONOS Ping for simple leaf spine architecture

[Charles Chan]

(+trellis-dev)

Hi,

I believe it is caused by subnet misconfiguration. Trellis doesn't allow one subnet to span across multiple leaves (with an only exception when these two leaves are paired).
For example, 10.6.1.254/24 is configured on both switches.

Thanks,
Charles

TOPOLOGY DESCRIPTION:

I have ONOS in a leaf/spine architecture. 

Here is the diagram of this -

Host 1 ==> Leaf1 (Whitebox switch) ==> Spine (Whitebox switch) ==> Leaf 2 (Whitebox switch) ==> Host 2 and Host 3

Between leaf1, spine and Leaf 2 we are running Segmented routing -

PROBLEM DESCRIPTION:

I am not able to ping between host-1 and Host-2

I am able to ping between host-2 and host-3 - in the same Leaf-2

Logs when the ping fail is -

"No Matching Batch for this error xid =0"

Not sure why this is happening

Need Help.

ROUTING TABLE IN HOSTS:

I have a default route point to the management interface and another specifc route to interface gateway of 10.6.1.254 - for leaf-1 GW.

Please help.

[Charles Chan]

I suspect that is due to the conflict between lldpprovider and netcfglinkprovider - you can have one at a time. You can try to remove netcfglinkprovider and see if the issue persists. There should be some other log (near this one) that provides more details. A full karaf.log will help.

Thanks,
