vMX AWS - Configuration

[Elena_Ge]

Hello everyone.

I am new to the forum, and I have seen that everyone shares their knowledge and experience, so I dare to ask, thanking in advance to those who take the time to read me.

I am currently trying to deploy a vMX on AWS in routing mode in the same VPC and same network segment where the resources I want to publish are located. Currently my vMX is single arm only which I understand shares LAN / WAN however I am in doubt as to whether both interfaces carry the same addressing or should they carry different. I would like to know your comments from experience.

What I am looking to do is that this vMX is the default gateway of the AWS network for communication to the internet and establish communication to the resources of other MXs.

I remain attentive to your kind comments, any contribution is welcome.
Regards.

The main instructions are missing some of the setup details.  You also need to do this:

You need to add a second interface.  You will end up with one WAN interface and one LAN interface.  I would place the WAN interface in a "public" subnet and the LAN interface in a "private" subnet (most likely, the one where your servers and resources are located).

Thank you for your support. With the addition of a new interface differentiating LAN traffic from WAN traffic, it has been useful in achieving the goal of making the vMX the internet gateway for cloud resources and the connection point to Meraki networks.
