[NANOG] NREN Network Design

[Tarig Yassin Adam <tarig () suin edu sd>]

I'm try to redesign the Sudanese NREN (National Research & Education Network). we provide end to end service,to our 
customers. Our network is build over local ISPs. But the problem of the current design that each time we need to go 
back to the ISP to change our Infrastructure IP addresses, when the situation need this.How can solve this? I heard 
about something called Virtual Network Environment which give us the full control of ISP routers, is it the best 
solution? What about others NRENs.Thanks
