I'm attempting to put together a small service provider network with a "design" that was decided upon before my arrival. I'm looking for input on how to best run iBGP across the Cisco devices. All of the ASR920's have limited capacity for handling routes so I figured I would just get each Cisco router two default routes, one for each Internet connection going to the same ASN right now. I plan to add another ISP in the mix out of one of the datacenters. I've had to implement FRR on Linux boxes because I didn't have anything that would support a full feed from an ISP. I though about running ERP between data centers for high availability, but could just as easily have the links be routed. The customers would be connected to each of the Cisco devices, using mainly ME1200. I hope the community has some thoughts. Thanks in advance.
