Redistributing EIGRP, eBGP and iBGP on one Cisco router.

Hi all,

Am just wanting to sanity check an option. We are upgrading our global WAN and I want to have an informed discussion with our provider. We have (for reasons) two networks that we bridge in our DC. This will remain. I want to simply the design to allow for SD-WAN to be implemented.

My simple question is: Is there any reason (other than size and no. of interfaces) that I can't join all of this into one decent cisco router?

Basically I'm wondering if there was a reason it wasn't done before other than them wanting to sell us more kit and monitoring services.

More info:

Ninja edit: This seems simple to me so what am I missing? https://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/113506-failover-eigrp-bgp-00.html Seems logical?
