1. thing you can try. try downgrading the r6900v2's firmware 1 version. there's been some concerns with the latest firmware and DNS not working properly.
2. if that doesn't work, I'd open a post on the pi-hole forum. I'm not an expert on it and mines running in a docker container so my settings might be slightly different. I know it works but can be finicky with how you setup the pihole. Its challenging to troubleshoot off the occassional screen snip.
From the routers perspective. I've only ever needed to plug in my IPv4 info on the internet setup, dns server page. And its worked. It was a bit more challenging when I enabled IPv6 but not a bunch. And i've used it on/off for a couple years.

I have my pihole configured to provide both DNS and DHCP. That way you get more info and the DHCP service provides the DNS address to each device via DHCP rather then the router's IP address. Works great and never down. Using a Raspberry PI 3.
