> We have switched to RA-Handling in userspace for similar reasons already so I guess it's only the next logical step to create separate routing tables for each upstream interface to do source-based routing and filter out ULA-traffic on this layer instead of through iptables.

don't do it per upstream interface, that wouldn't work. per next-hop might. the draft suggests a single table with source constrained routers and backtracking.

> Having one central userspace management daemon for routing and address / prefix delegation in general might not be the best or cleanest solution in the end but I guess there is no better way right now.
