Hi, I am renting rack space in two datacenters for hosting customers websites, and right now i have different customers hosted at each datacenter. I am getting IP allocations from my ISP and I use these for my customers websites. I have a /26 at each location. There is only one ISP (the same one) in the two datacenters, and it has two upstream connections to Tier-1 providers.
I wanted to establish a high speed private link between my two sites, so I can have high-availability and failover for my services such as the customer portal. The datacenter offers a 1Gb fiber circuit between the two sites.
My only layer3 devices at each location are Palo Alto firewalls (PA3050) and I only have a single ethernet hand off from the ISP (100mbps) connection for my internet connectivity at each location.
Can I run BGP in this setup? Or is there a better approach to achieve what I am looking to do? I am attaching a basic diagram.
After getting the BGP (or other routing protocol) working between the two sites, will this be considered a "dual homed" setup? (This will also help me apply for ARIN address space because now I have to use IPs from my ISP)
I read that these Palo Altos can only run around 46,000 routes so I am not sure if I can use them for this setup?
