Well, this can ofcourse then be taken to the extreme. Let's assume that I am cost concious resdient with a sattelite down-link (yupp, they exist), and a DSL line and a Cable link. Should I not be allowed the same easy choice of up-link as the corporate world?
Let's then assume that I have my home on VoIP only so NAT is out. Do I get my own AS-number and PA space then?
You are using three different IP addresses that are dynamically (OK. If you insist statically) assigned to three different links. But how can I reach your web server ? This is different from the corporate world to have the same IP coming in from different links.
I think we all agree that the current routing model is broken and no longer does what we would expect it to do. However, I think Randy is right in that this will take at least 5 years to redo though. Just look at addressing / CIDR /IPv6. That has taken what, 8 years? At least, and we are not really near any deployment. A CIDR like solution of this is simple. Filter.
Maybe you are willing to black-hole some /24 block like eBay ?
In this situation the most popular solution for local customer, who needs reliable and cheap IP uplink and high speed access to regional Internet resources, is to build two channels to local ISPs (not so reliable, but much more cheaper than even one external uplink) and to local IX.
In this SOHO situation you don't need a seperate entry in the global routing table. Also the point is two links (phone line won't die the same time as the satellite, will they ?)
IXes are a bad example as just beeing present won't do. You need to get peers as well. And if you are a company my guess is that most providers rather sell you bandwidth than peer.
This is going backward to ask company to have full mesh among all the ISPs ? Ping Lu Cable & Wireless USA Network Tools and Analysis Group W: +1-703-292-2359 E: plu@cw.net
