The loss happens only on one mesh point, other = mesh points work well. By default bla is enabled on all of the mesh point.=20 Can disabling bla on non-backbone mesh point help to improve the mesh = network's overall performance?

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. :) Cheers, Simon [1] = https://www.open-mesh.org/projects/batman-adv/wiki/Bridge-loop-avoidance-= Testcases#A-client-switches-its-gateway-due-to-loss-of-linkbetter-TQ On Monday, October 15, 2018 2:34:53 PM CEST gary wrote: > Hi, guys, >=20 > I meet an issue related to bla. > There are two backbone nodes on backbone LAN, and many mesh nodes=20 > connected with the two backbone nodes.
