BM 20x20 router used as upstream switcher?

Possible sync/delay issues with a router...??
I was recently at a studio that used vMix on a laptop as its production switcher, being fed sdi via thunderbolt 3 with an AJA I|O box. With 1 of 4 connectors being used for Pgm out that left 3 to feed vMix. So whoever engineered the studio, (and was not present when I setup for a project), used a 20x20 BM router to expand the number of possible sdi inputs that could feed the AJA. A Streamdeck controller with Companion software then switches both the upstream router and the AJA I|O connector that vMix uses.

I've done this with my ATEM Production 4k because the ATEM will cleanly switch sources. But it seems like using the router, which wasn't designed for clean switching would run into sync issues, glitching etc. Any thoughts on using the router as an upstream switcher?

FWIW, I bypassed the router for this project so never experienced how well the setup would work.

as long as you use the router to change sources that are not yet on air, you should be fine, the only glitching will occur on the preview windows, and vmix will sync all sources for processing anyways.

BMD have CLEAN FEED router too ..
