Using configuration from a 1921 router to configure an MX84 SDWAN

[mcoomber]

I've got a Cisco 1921 Series router and an SDWAN within my network. 

The link from the service provider connects to the 1921 Series router and the router connects the SDWAN.

I want to take the 1921 router off the network. 

Before doing so I want

1. Can the configuration in the router be configured in the SDWAN
2. Below is the configuration from the router. How can this be translated to the routing config in the SDWAN. 

The aim to have the connection from the ISP directly connected to the SDWAN since its already configured as the default gateway and Firewall. 

Thanks

Most settings can be translated for use on the MX.

You will see that at Meraki things are simpler, for example you don't need to do an outbound NAT for the internet, just configure the interface with the IP provided by the operator and plug the cable into the wan and it will work.

I have configured interface GigabitEthernet0/1 on the router to Port 2 on Meraki and interface GigabitEthernet0/2 on the router to Port 1 on the Meraki. 

Without configuring NAT, do I need to configure the static routes and ACL? If so where in the Meraki do I do these configurations

Thanks for the support thus far.

It's a bit confusing what you want to do, can you illustrate it in a simple way?

I just want to configure the present configuration in the router to the MX 84. 

So I want to know what configs in the router I need and which I can skip. Also which config Meraki corresponds with the config on the router. 

Thanks.

[alemabrahao · Accepted solution]

You just need to configure your WAN interfaces with the IP that the operator is providing you. And for each of your internal networks you need to create an SVI in the MX.

Ideally, you should send a simple topology to be more accurate.

Configuration on the MX is relatively simple, you don't need to create NAT or ACL for it to be able to communicate with the internet.

Thanks very much for the support and guidance. Will revert to you tomorrow after configuration.
