Hi Nanog...looking for some advice. I have a customer who has a large network...approximately 130 sites across the US. Each site is fed via two providers, via two Separate CE Routers. It's a L3-VPN service. Each provider currently provides connectivity for 6 VRFs, each over a single service multiplexed UNI. Ie...there are 6 dot1q interfaces facing each provider, each sub-interface is in its own VRF. The network is going through a redesign, and one of my tasks is to consolidate and "streamline" IP addressing. Looking for a sanity check...I have this idea to make every dot1q sub-interface facing the provider the same point-to-point subnet. Specifically, facing a single provider, I want to use the same /30 subnet for all 6 VRFs. I'd use a separate /30 for each of the CE routers per site, so I could go from 12 /30s to 2 per site. I should note, PE-CE protocol is BGP, and behind the CE routers is a small iBGP network. I know it's technically possible to configure the OPs this way and under normal circumstances its fine. But, in this case, there is a whole lot of route leaking / cross target exchanges happening between VRFs. I still think it's okay...but can anyone think of a a failure mode that I may not have? Is what I'm thinking common practice? Is there a best practice for this sort of thing? Thanks!
