Apparently I can work around this problem by explicitly disabling
IPv6AcceptRouterAdvertisements for enp2s0 and enp4s0:
$ cat /etc/systemd/network/51-enp2s0.network
[Match]
Name=enp2s0
[Network]
Bridge=br0
IPv6AcceptRouterAdvertisements=no
$ cat /etc/systemd/network/51-enp4s0.network
[Match]
Name=enp4s0
[Network]
Bridge=br1
IPv6AcceptRouterAdvertisements=no
$ ip -6 r
2001:470:1234:10::/64 dev br0 proto ra metric 1024 pref medium
fd01:470:1234:10::/64 dev br0 proto ra metric 1024 pref medium
fe80::/64 dev br0 proto kernel metric 256 pref medium
fe80::/64 dev br1 proto kernel metric 256 pref medium
fe80::/64 dev enp2s0 proto kernel metric 256 pref medium
fe80::/64 dev enp4s0 proto kernel metric 256 pref medium
default via fe80::92f6:52ff:fef6:c88 dev br0 proto ra metric 1024 pref medium
But it does feel weird having to do this explicitly for a lower bridge
member (and yes, I'm also slightly surprised about the (fe80::/64
routes for enp2s0 and enp4s0, but this isn't new).
