In addition, I’d recommend dropping the /64’s from your loopbacks. I know IPv6 = all addresses are free now but still…
Personally I use /128 for loopbacks (like /32 w/IPv4) and /126 (like /30 w/IPv4) for point-to-points. It’s easier for me to relate and definitely stresses a large network plan a lot less. I chose not to use /127 as I could find less evidence that it as widely supported (similar to /31’s). That and I like my even numbers, it calms my OCD.
Also, mac sure your loopback bridges have MAC addresses. A generous and intelligent user helped me figure this out when I got my first RouterBoard.
