Loadbalancing Issues

[Fabian1]

Hi everyone,

on our new site, we have two 1Gbit uplinks that I configured in a load balancing with autovpn active active.

We have some strange behaviour in our network that some applications need more time than expected to connect so servers over the autovpn tunnel and sometimes they fail completely.

Now we deactivated loadbalancing, these applications work again...

Does anyone got the same problems or is this something I have to fix with Meraki support?

I'm thinking of enabling load balancing again and simply deactivate autovpn active active so that the apps only use one way to aws.

Internet traffic is fine, it's only a problem with traffic over the autovpn...

Best

I’ve not seen this behaviour personally and we have plenty of customers with the same setup.

What applications are struggling?  Can you not route them specifically out of one circuit?

We have problems with network shared folders, that sometimes users don't have access to their folders anymore and a message comes "The Local Device Name Is Already In Use" 

Most of the other stuff looks good, but this is getting annoying...

Try creating an SD-WAN flow preference to force traffic for specific servers having an issue to only use one of the two circuits.
