Multiple default gateway from tinc node

[Bright Zhao]

Hi, Tinc expert

If there’re multiple tinc nodes announce default route in their host configuration of Subnet = 0.0.0.0/0, how for the remaining nodes to select which is the best route to get out?

All of them participant in the same tinc net.

I did some test, like A as the branch, B,C,D as the nodes to announce default route; when all up , A select B, but if B down, A will go C, C down, A will go D, but is there any rules?

Also, if the connection is in a hierarchy, and enabled IndirectData = yes everywhere, so the tunnel only follow the meta connection, if this is the case, what’s the default routes selection rule?
