MerakiMX64 on prem, vMX100 in Azure and two server farms, one in classic and one in modern architect

Hi there,

 

The company that I am working for is implementing MerakiMX on-prem and in Azure.

 

On prem I have:

- one MerakiMX64 with subnet 192.168.20.0/24 and a Client1 with ip: 192.168.20.2 that is behind MerakiMX64

 

On Azure I have:

 

- one vMX100 on a vnet called meraki-lan. The vMX100 has IP: 192.32.0.4, subnet 192.32.0.0/24

 

- one server farm that is deployed in classic architecture (older one). The servers are connected to a vnet1 that is in classic deployment. Subnet for the servers 192.31.0.0/25. There is one more subnet called GatewaySubnetV1 192.31.0.128/29, this one is used to make a vpn-site-to-site connection via virtual gateway to GatewaySubnetV2.

 

- one server farm that is deployed in modern architecture. The servers are connected to a vnet2 that is in modern deployment . Subnet for the servers 192.32.0.0/25. There is one more subnet called GatewaySubnetV2 192.32.0.248/29, this subnet is used to make a vpn site-to-site connection with the GatewaySubnetV1 192.31.0.128/29

 

I have done peering between meraki-lan and vnet1 and meraki-lan and vnet2. There is a routing table that I have put the local subnet 192.168.20.0/24 and associated that subnet to vnet2.

Now everything works as it should between 192.168.20.0/24 and server farm that is deployed in modern architecture, vnet2. From Client1 I am accessing all servers on vnet2 (modern architecture)

However I am not able to communicate between the MerakiMX64 or Client1 to servers in vnet2(classic architecture). I am not able to find how to make an association from meraki-lan to vnet1 (classic architecture).

Any advice how to solve this problem?

Thanks J.

Hi to all,

I just wanted to post a solution that worked for me.

 

The solution involved using powershell to create a routing table in Azure classic and associate that routing table to the network that is in classic deployment.

 

Here is a nice document that helped me https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-create-udr-classic-ps

 

In case anybody else needs some help with this kind of problem i will be more than happy to help :).

I don't know the answer.

 

What about building a VPN between the classic and new architecture networks?

Hi PhilipDAth,

 

Thank you for the reply.

 

I have been trying that too and was following the documentation, guides but unfortunately never got it working. The VPN tunnel never got established :(.

 

Have you come across some useful documentation that can help me to try again?

 

Thanks in advanced.

As you added a route table on resource group where vnet1 belongs, you will need to create a route table on the resource group where vnet2 belongs. And put the LAN ip address of vMX.image.png

I used the youtube to set up my vMX @ Azure.

Hi Happiman,

 

The thing is that this is not possible when there is a network and a server farm deployed in the classic environment.

 

You are not able to associate the vnet that is deployed in the classic environment with routing table.

 

I send the same question to Microsoft support and will share the solution when they will reply to me.

 

Thanks for the feedback :).
