TINC subnet up/down loop #424

Open ptorrent opened 1 year ago

ptorrent commented 1 year ago

Hello,

This is how looks my network:

When NODE X is connecting to A and B all network going down/up/down/up.

We even receive subnet up from nodes that are turned off!

NODE A version = 1.1pre18 NODE B version = 1.1pre18 NODE X version = 1.1pre18 Other nodes= 1.1pre18 or 1.0.36

Don't know if the project is still alive.. but i repeat I can help about this issue by giving server/nodes access..

Thanks for your help

This is likely caused by node X not being able to handle all the subnet updates it receives in a timely, causing PING timeouts on its connections, causing things to go up and down.

Also, some nodes could have old information about subnets and their reachability. Normally all nodes are supposed to converge to the same knowledge about the state of the network, but it could be that this is not working well when X goes up and down repeatedly.
