Two ASN and two subnets over single link to same ISP
I'm trying to determine if this is even possible, and if so, is there a good document or configuration example out there? We just received a /24 from our ISP along with our own ASN. Currently we still have a /26 through the same ISP using a different ASN that will eventually go away once we are fully transitioned to the /24. For now the /26 must be active until we move some VPN tunnels and change vendor whitelists of our current IP address. Is there a way to advertise both networks over the same link? I was reading about local-as. Would that apply to this case?
