Hello, guys.
Does anybody know if BLA is somehow connected with gateway mode ? In short, I'm unsure if gateway mode algorythms influence only DHCP traffic. It is not strictly said. Documentation about BLA II use term "gateway". As afr as I understand, there maybe case when BLA gateway is one node, and DHCP gateway is another one. So, the question: does GW functionality influence BLA algorythms ?

No it isn't connected.

Correct

Hi, guys,
I meet an issue related to bla. There are two backbone nodes on backbone LAN, and many mesh nodes connected with the two backbone nodes. When I run ping test on one client, there is about 20% packet loss. And I find out the packet is always loss when the client is switch from one backbone node to another one(observing "batctl cl" on backbone node).
Do you have any suggestion for the issue?

Hi Gary,
when the loss happens, for how long does it happen? Do you see where/why the ping packets get dropped? That should be the first step to find out, IMHO.
Changing the gateway should be working in general [1]. It's also possible that the loss is mesh related and the gateway change happens due to a node failing in your mesh - that would be a problem independent of BLA.
I hope those suggestions help you to find out the problem. :)

Hi Sinon,
Thanks for your tips. The loss happens only on one mesh point, other mesh points work well. By default bla is enabled on all of the mesh point. Can disabling bla on non-backbone mesh point help to improve the mesh network's overall performance?

I don't think this will help. If they are not on a shared backbone, BLA will not do much more than sending an "announce" frame every 10 seconds. This shouldn't have performance implications.
