I’m having a bit of a dilemma.
We’re upgrading our datacenter infrastructure with a couple of Nexus 9Ks, which will take on multiple roles - L2/L3
I have a VPC configuration set up. We’ll be acting as ISP for multiple clients, each getting a /30 subnet assigned.
My question is, how can I ensure we have routing redundancy in my case? VRRP or HSRP won’t work as far as I can tell, since I need a /29 at least. Is there any other way to have a common routing table? I know that some L3 switches do have that when stacked.
I’ve seen workarounds using secondary IPs, but can anyone confirm if that actually works?
Looking forward to your feedback!
