Hi
After upgrading from Alice 6..0.0 to 6.1.0 we noticed that there seems to be an operational issue with OpenBGPd 8.3 and 8.4. This I used with OpenBGPd-state-server.

The issue seems to be the Alice neighbour summary refreshes to only see one neighbour which turns out to be the last neighbour in the OpenBGPd neighbour summary . This happens within a minute of restarting AliceLG. We reverted back to version 6.0.0 and this works fine.

Looking at the logs for AliceLG It the following is observed on the neighbour refresh,

This behaviour is seen both with cache_ttl 0/unset and the cache enabled with a cache_ttl, such as 100.

This is indeed strange. I'm looking into it.
