The information I have obtained from the supplier is as follows.
Router ASN:AS56655
Router endpoint:2a03:94e0:f254::
Your endpoint:2a03:94e0:ffff:185:243:218::43
Multihop:Yes
Route table:Full
So I did a route trace.
root@debian:~# traceroute -s 2a03:94e0:ffff:185:243:218::43 2a03:94e0:f254::
traceroute to 2a03:94e0:f254:: (2a03:94e0:f254::), 30 hops max, 80 byte packets

Some other route trace.

In fact my gateway should be 2a03:94e0:ffff:185:243:218::1
I set up a static route in Bird2.
protocol static {
ipv6;
route 2a03:94e0:f253::/128 via 2a03:94e0:ffff:185:243:218::2;
route 2a03:94e0:f254::/128 via 2a03:94e0:ffff:185:243:218::2;
route 2a12:f8c0:6960::/48 reject;
}
The issue was not solved when 2a03:94e0:ffff:185:243:218::2 was modified to 2a03:94e0:ffff:185:243:218::1.
All routes are stored in lo, making the network inaccessible.

How do I get the route to exist on the correct interface (vmbr0).

I've spent over a week on this but I can't find out what the problem is, so I'm asking for help.
