Hi

Do not see any issues on BIRD side. It seems to me that Cisco just resets
the exchange (by sending DBD flag I) when it should be done (or in Loading
state):

May 31 13:09:16.280 UTC: ospfv3[1021]: ADJ: Recv DBD fr <server> on TenGigE0/1/0/23.4 seq 0x8ce5d6a opt R/E/V6 flag NONE len 28 mtu 1500 state EXCHANGE
May 31 13:09:16.280 UTC: ospfv3[1021]: ADJ: Send DBD to <server> on TenGigE0/1/0/23.4 seq 0x8ce5d6b opt R/E/V6 flag I/M/MS len 28 mtu 1500

So any explanation of this has to be found in Cisco side,

I suppose that this exchage repeats indefinetly and 'show ospf neighbors'
on BIRD also shows the other side in ExStart/Exchange?
