Do you see where/why th= e=20 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 t= hat=20 the loss is mesh related and the gateway change happens due to a node faili= ng=20 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-avoidanc= e-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 connect= ed > with the two backbone nodes.
