MX84 with BGP Protocol

Hi All,

We´re working in a project, where the customer have 02 ISP providers (they are an autonomous system)

My question is: can I connect  the 02 links directly on MX84 configured with BGP protocol or, must I have to connect a front end Router, such as a ISR4331 (see attached topology)?

Best Regards,

First, the MX BGP support is only for AutoVPN routes, so it can't be used for this scenario:

https://documentation.meraki.com/MX-Z/Networks_and_Routing/BGP

So assuming you have your own public prefix and public ASN, you are probably going to want to use the 4331 and have it do the BGP for you.

 

The other alternative is to not use BGP.  To simply have each ISP statically route your public prefix down the respective circuit, and to distribute this static prefix into BGP at each of their ends.

Then you can use the MX load balancing option to control which circuit is being used.

Using the 4331 will give you the most control - by far.  I would probably go with the 4331 option if it was me.

Is that O2 land line ISP or LTE ISP service? It makes a difference.

Could you explain about O2 land line ISP and LTE ISP service?

In some countries O2 offers a fixed line service such as - https://www.o2.co.uk/business/products/broadband/high-speed-internet 

also there is the mobile LTE service - https://www.o2.co.uk/shop/inspire/mobile-broadband-explained#section4 

The maximum speeds available depend upon country and location within that country.

Hi Robin,

the two links of the customer are dedicated (fixed line services), with BGP protocol.

Each link is 100Mbps, and different ISP´s.

We´re plannig to change the actual equipments (linux based) to MX84 and ISR4331 (cisco router), like the topology.

Philip,

Thank you very much.

I´ll follow with 4331 in front of MX84

You'll need a router in front of the MX to run BGP. Or you could just allow the ISP's to do the BGP as @PhilipDAth suggested.
