Thanks, that clarifies things a lot. It seems my ISP requires a GUA on the
external interface for routing to work, but fortunately (like you)
assigning a /64 (or /128) from the /56 prefix to the external interface
works.
When I was trying to get things to work, at some point I had two "request
prefix delegation on em1" lines, one with just "for {em1}" and the other
for the internal interfaces. This worked, but I later noticed that that
resulted in me successfully getting *two* /56 prefixes. That was a bit
surprising, so I changed things to the one prefix.
