How to block tinc node advertise it's neighbor/edge/subnet info to another node?

[Bright Zhao]

Hi, Tinc experts


There’s a requirement, where A connect to B, B connect to C; where B knows all the subnets from A and C, but A wouldn’t need to know anything about C, and C wouldn’t need to know anything about A.

Any tinc configuration can make this happen?

You can think of B is not an interconnect/forwarding node, instead, it only connect to A and C separately.

I can think of run two tinc network which are two processes, other than this, any other easier way to make it as one network, but B doesn’t advertise the info from one side to the other side?
