Routing help with MX100

Hi Guys,


Im quite confused right now if I was able to configure everything correctly. For any routing expert out there, may I seek help please?


My issue is I want Branches A, B & C talk to Branches XYZ back-to-back thru Meraki having different network provider with different physical circuits. (please see connections below)

If this might help explain the issue much further:


Provider 1 Routing table sample is below: next hop next hop and so on..

Meraki Routing table next hop next hop next hop next hop


Provider 2 Routing table next hop next hop and so on...


after configuring allow rule on L3 Firewall on MX100, Branches ABC cant still see Branches XYZ, am I missing something?

also for the port on meraki, should I switch it to Trunk?

Kind of a big deal

Actually, I don't really get what you are trying to achieve.

Most important is, that your MX-Ports in use are two LAN-Ports and not the WAN-Ports. For these two LAN-Ports, Access is perfectly fine.



You say "ABC can not see XYZ". Does this mean the other direction is working? Or in general: What is already working? ISP1 to ISP2, ISP2 to ISP1, any Branch to MX, any Branch to the other ISP?

How do you test? Are your test-packets allowed on the target-devices?

Thank you for this, got totally confused yesterday and forgot to test both sides of the network, will update my post later. Thanks again!

To see dynamically learned routes on a router you need some kind of dynamic routing protocol. Have a look at this link to achieve dynamic learned routes from/through a MX.
