(Unsure if this is the right forum to ask this question, but here goes:) From what I understand, IP Anycast can be used to steer traffic into a server that's close to the client. I am curious if anyone here has/encountered a setup where they use anycast IP on their gateways... to have a predictable egress IP for their traffic, regardless of where they are located? For example, a search engine crawler could in principle have the same IP advertised all over the world, but it looks like they don't... I wonder why?
Hi Vimal, I'm not sure I see what the benefit would be here. Maybe if you explain what exactly you're trying to accomplish, someone can point you in the right direction? What you're describing here isn't really analogous to how anycast works. Anycast isn't really a protocol in and of itself, it's simply the act of advertising IP space externally in a diverse way and then routing that traffic to the nearest capable host once it's inside your network, rather than to a single very specific host that exists in one specific place. - mdh
