Hi List,

We are looking to move our non infrastructure routes into iBGP to help with our IGP scalability (OSPF). We already run full BGP tables on our core where we connect to multiple upstream and downstream customers. Most of our aggregation and edge routers cannot hold full tables and it's certainly not possible to upgrade them. Is there any reason why we shouldn't filter iBGP routes between our core and aggregation layers (we plan to use route reflectors) or should we be look at using a private AS number per POP?

Thanks

Dave


エッジでiBGPを動かしてるとフルルートを持てない、Upgradeも不可。
IGPのスケーラビリティを上げるにはどうしたらいい？
という質問。
フルルートが30万経路に届きつつある現在、ネットワーク事業者にとって切実な問題かも。

返答として経路の集約、BGPコミュニティで頑張れ、というものが届いてきています。
