MMR Infra Design advice

Hi there,

I am wanting some architecture advice.

Problem

I want to place an Arista DCS-7280SR-48C6-F in one MMR (DC#1) and rent darkfiber to connect to another MMR in DC#2..

The goal is to reach IXP's and iptransit providers that are available in DC#2 which are not available to me in DC#1.

Question:

Should I put another router like Arista DCS-7280SR-48C6-F in DC#2's MMR or could I just get away with using a network switch in DC#2's MMR in order to pass traffic over the fiber back to DC#1's Arista Router?
