Follow up 2:

it seems that bird1.6 behaves differently to bird 2.0.7:

bird> show route all for 2a0a:e5c1:111:111:6aa6:5bc:535a:8e21
2a0a:e5c1:100::/40 via 2a0a:e5c0:1:8::6 on bond0.8 [router2_place6_ungleich_ch_v6 2019-12-03] * (100) [i]
        Type: BGP unicast univ
        BGP.origin: IGP
        BGP.as_path:
        BGP.next_hop: 2a0a:e5c0:2:2:0:84ff:fe41:f24d
        BGP.local_pref: 500
bird>

(this is from the 2nd router pair, still running bird 1.6)

Is it possible that the nexthop resolution algorithm changed in bird2 vs
bird1?
