I have two standalone master controllers that are geographically separated for redundancy and both have PEF for VIA enabled. They are not clustered or VRRP'd in any way...completely standalone, each serving its own users. They are redundant for RAPs and VIA only.
For Site A I have the VIA connection profile configured so that Site A is primary and Site B is secondary. If you were to inspect the VIA client connection profile for users at Site A you'd see 2 entries (VIA Connection Profile_0/Site A, and VIA Connection profile_1/SiteB).
My question is, if the controller or Internet goes does at either location, is there a way to set up the VIA client to auomatically fail over to the connection at the other site? Through all of my testing it appears that this is a manual process, i.e. user would have to go into the VIA Client/Settings Tab, click the drop-down menu for the connection profile and select the other site, then click Connect. I'd like to know if it is possible for some sort of preemption to be enabled on the VIA client, so that when the primary site is unreachable it automatically failes to the backup. When the primary returns the client would re-establish with it and leave the backup. I have this configured for all of my RAP's, but wasn't sure if VIA can do the same thing.
