If you are only using Bird for the radv protocol, you should probably just let everything default to using the 'master6' table, and make your life simpler. You can remove the 'kernel' protocol completely, change the 'static' protocol and the 'radv' protocol to not specify a table name, and 'show route' will give you the result you are looking for without having to specify a table name.
I'm beginning to understand. Can I use table names for policy routing? I don't know what protocol I need. It is a new question. I should know what protocol is using the next hop on ppp0 (default gw). I'm not even sure what IPv6 hosts are out there; traceroute shows nothing. Running traceroute from an external site I find that, wherever the trace starts from, it falls into a loop: 2a00:6d42::1:0:1:36 Aruba S.p.A. (sometimes ???) 2a00:6d42:0:2:5::12 " " 2a02:29e1::a Seflow s.r.l. --> _my ISP_ 2a02:29e0:109:ff00::5 " 2a02:29e0:255::2 " 2001:7f8:c5::a503:1034:1 Samer Abdel-Hafez (sometimes ???) The bottom one, from Amsterdam, points back to Aruba in Italy. One of the three 2a02:29e0/30 should point to me instead of returning "uphill". I guess I should advertise something, but don't know how. nmap finds nothing, but confirms those hosts are up: 597-north:bird# nmap -6 -e ppp0 -Pn -T4 --system-dns 2a02:29e1::a 2a02:29e0:109:ff00::5 2a02:29e0:255::2 Starting Nmap 7.80 ( https://nmap.org ) at 2023-04-25 18:05 CEST Nmap scan report for 2a02:29e1::a Host is up.

(Or maybe there are some fe80 hosts I don't see?) My ISP say everything is fine on their side, and if I used an external router such as TP-Link, ZTE, Mikrotik or Fritz!box they have guides, but not for Linux box. What advertisements do those routers run? (The guides talk about DNS and DHCP, which I don't think I need.)
