Hi!
my goal is to have a rb5009, which can be connected to any internet connection (it just needs to be provided an IP via DHCP). The rb5009 establishes a Zerotier connection to the other routers in the same Zerotier network and route clients behind it through it. That's easy, now the more complicated stuff, I want to route networks via Zerotier that are maybe overlapping the subnet the rb5009 is connected to the internet.
e.g. the router of the Internet (not under my control) uses 10.0.0.0/24 - and I want to route 10.0.0.0/16 via Zerotier, which will not work as 10.0.0.0/24 is more specific and so traffic to that subnet will be routed locally. I can now configure a VRF for the Zerotier interface and the Client interface, so the client traffic go the correct route. But that does not help if my rb5009 wants to connect to a server (e.g. dns, syslog, dhcp, snmp traps, ....) or the other way around I want to ssh into the router or query it via snmp from a network which is overlapping that local network.
What I want to do is to configure the router in a way that Zerotier/Internet is not in the default/main VRF - but I don't see a way to do it. What I'm missing? What are possible solutions/workarounds?
Thx for your help!
Regards,
Robert
