Dual Wan + BGP + public ip assignment to WAN1 - what happens?

I have two WAN connections. SFP1 and SFP2. I also have a /24 public IP (let’s call it x.x.x.x) block that I’m advertising to both of my WAN upstreams.

A few questions:

  • If I assign x.x.x.1/24 directly to the SFP1 interface, does anything “funny” happen when traffic needs to be routed via SFP2?
  • What would happen if I also assigned x.x.x.2/24 to SFP2?
  • Is there a better way to assign public IPs to my external interfaces in this scenario where those same public IPs are being advertised to two upstreams?
  • If I want to NAT traffic to x.x.x.3, should I make any special considerations?

Thanks for the suggestions.

We are not in your head.
At least provide a network diagram…
