[c-nsp] BGP Considerations isolated PoP

If I understand correctly your third pop will not be connected to your existing 2 pops ?
In that case you will need to set up IBGP via tunnels , it's not pretty but it'll work. 
Or divide your /16 so that the third pop announces part and the other 2 pops announce part and add static routes for connectivity between the POPs. 
Your AS will not get announced back to you from your upstreams in BGP.

Hi,

 

We have our public AS announcing our /16 network over 2 PoP's to single
upstream providers two adjacent PoP's. iBGP configured as it should be.

 

What are the considerations if a third PoP were to be implemented, yet
this would, for the time being, be essentially isolated from remainder
of our network?

 

Thanks.
