Hmm? We solved this long ago in cerowrt, openwrt, and in linux, by using "source specific routing", which is the default for many openwrt derived OSes. Basically it looks like this: ip route add from 2001:abcd::/56 via whatever ip route add from 2001:dbcd::/56 via whatever2 You then distribute both sets of ipv6 addresses to the clients. Simple clean and it solved the bcp38 problem because there is no default route for any but these ipv6 addresses in the system. It works well for vpns also. Happy eyeballs takes care of the rest. https://datatracker.ietf.org/doc/html/draft-ietf-babel-source-specific-08 describes how we added it to the babel routing protocol as well, so best hops can be easily chosen in a more complex network. In case I had 5+ comcast uplinks spread across a wifi campus so having multiple uplinks and failover was needed. It's been up and running for... 7 years? https://en.wikipedia.org/wiki/Source-specific_routing also made it into a few other places. I'm pretty certain every other OS completely missed this key feature of course including your mikrotik > > nb > > > On Mon, May 17, 2021 at 2:36 PM David Lang wrote: >> >> On Mon, 17 May 2021, Nick Buraglio wrote: >> >> > Inline >> > >> > On Mon, May 17, 2021 at 2:15 PM Dave Taht wrote: >> >> >> >> Starlink provides a router, also?
