I have a Dual HUB datacenter that I want to run VXLAN BGP EVPN, to stretch the layer 2. (To take advantage of clustering services) I've been thinking about optimal path routing. The remotes will receive dual (ex. 192.168.10.0/24) from both hubs. To o...

I have in fact, verified this process works. I will say, make sure you rename the packages.conf in flash on all Stack members. And I just renamed the existing packages.conf to packages.conf.old.When the switches were reloaded, "sh install summ" showe...
