Help configuring multi-DP routing

Hello all,

I can’t seem to get inter-vlan routing working at all. I have a Zodiac GX that is connected to a Zodiac FX - I believe I have trunked them together correctly (yaml config below). I can successfully ping the faucet_vip address of a vlan from a host attached to a port in the same native vlan (e.g. host with ip 172.16.0.50 connected to interface 1 on the Zodiac GX can ping 172.16.0.254). However I cannot ping from a host with ip 172.16.0.50 connected to interface 1 of the GX to a host with ip 10.0.0.50 connected to interface 2 of the FX.

I have set the Default GWs of both hosts to there respective faucet_vip.

(Zodiac GX interface 4 is trunked to Zodiac FX interface 1)

I hope this makes sense, please help 😃

Yes by the two routers I mean 172.16.0.1 and 172.16.0.254. You aren’t meant to route inside a single L2 domain and you have to remember that Inter-VLAN Routing (IVR) in faucet is real L3 routing.

Something more like this work work better:

To actually get internet in this setup you will need to setup some additional NAT rules on your OpenWRT router and also add a static route inside VLAN10 for 0.0.0.0 toward 10.0.10.1.

Glad to hear the GX now works as expected.

Regarding the Zodiac FX problems, could you let me know what firmware version you are running? I will spin up one of mine here and see if I can track down the problem the tagged VLAN problem. Zodiac FX is an open source project so best we can do is submit a bug report on their repo and see if they are able to fix.
