Are there resources to help convert the config from a 1921 to a new MX100?

I am staring at this 1921 configuration trying to figure out how to mirror it on a new MX100. Admittedly, I am a novice with all of this, and am in over my head. 

 

Does anyone have suggestions on how to best navigate this migration?

Hi! I´d like to know what kind of configs do you have? Bc with MX you´ll have a little bit limitations than other cisco routers. For sample NAT between VLANs 

I have access to the 1921, so I can get a copy of anything that is needed. Right now I am looking at the running config.

Just try to gather what is the role of this router in your network. And what configs do u have to compare the MX´s capabilities,

Kind of a big deal

Okay, so you have a 1921. What role was it playing for you? Is it your immediate 'edge device' - connects to your ISP's equipment?

 

What device is in between that 1921 and the rest of your network? This may change our advice.

 

The first things I'd look at:

 

1. NAT statements

2. Port forwarding

3. Access-control lists

4. Subnets in use

5. VLANs if applicable.

1921 is the edge. 

Inside there are Cisco Switches (3560's and 2960's)

 

I wish I could just post the whole config here, but that's not a good idea. 

 

Many NAT Statements

Don't see any port forwarding

Several ACLs

Subnets and VLANs

 

Not a simple config by any means.

And the NAT how is it? Is it an outside NAT to you WAN role ports?

ip nat inside source static tcp x.x.x.x 25 interface GigabitEthernet0/1 25

 

Lots of those...

If this nat is from LAN to WAN it´s possible, actually it´s a Port forwarding NAT a MX would perform this without any problem!

Ok, good. I think I can figure that out. 

 

How about this. Setting up the VLANs I see... would the subnet for this be 10.19.223.0/24 and the mx ip be 10.19.223.61?

 

interface Vlan25
description Production$FW_INSIDE$
ip address 10.19.223.61 255.255.255.0
ip access-group inside-out in
ip flow ingress
ip nat inside
ip virtual-reassembly in
zone-member security in-zone
ip policy route-map web-traffic

It appears to work fine with an MX.
Just the routemap you cannot configure an explicit route map.

No way to do object-group network?\

 

object-group network AB07-RDP
host 10.19.223.181

Currently not, Objects are (still) in Beta right now.

How about "ip nat inside source route-map"

I think it would be best to use the Cisco partner locator and find someone near you to do this conversion.
