Spoke-2-Spoke Communication!

Greetings,

 

I want to establish that spoke-2-spoke communication in a VPN tunnel. I am using MX600 in my HO and i.e. HUB. on 2 locations using MX65w - Spoke & on 2 locations using cisco router. All 4 sites are connected with HO through VPN but spoke cannot communicate with other spoke. Kindly help me to fix this issue.

If you are trying to communicate from spoke to spoke why don't you just set all MX's as a hub (Mesh) VPN?... https://documentation.meraki.com/MX/Site-to-site_VPN/Configuring_Hub-and-spoke_VPN_Connections_on_th...

As @Nash already mentioned, we first need clarification if the OP is talking about AutoVPN or not. But let's assume he is.

 

@Network-dad it's not necessary to set them up as mesh to make the spokes communicate each other. By default the site-to-site VPN firewall allows communication between subnets that participate in AutoVPN. The packets will be routed over the hub in a hub-and-spoke configuration but it should work fine.

 

So @khurram , what is your site-to-site VPN firewall configuration? This is the default and should allow inter-spoke communication:

And have you included your spoke subnets into VPN? In other words, is the dropdown set to "VPN On"?

Kind of a big deal

Let me make sure I understand here:

You have an MX600 as your HUB.

 

Two sites are using MX65W.

 

Two sites are using Cisco routers.

 

Are you using AutoVPN between the MX65W and the MX600, or a regular third party tunnel?

 

Edit: If you're using AutoVPN with your Meraki devices, they won't be able to talk to your Cisco routers. Aaron Willette has a design for allowing AutoVPNed Meraki devices access to resources over other tunnels: https://www.willette.works/merging-meraki-vpns/
