This talk presents ViAggre (Virtual Aggregation), a ``configuration-only'' approach to shrinking the routing table on routers. ViAggre does not require any changes to router software and routing protocols and can be deployed independently and autonomously by any ISP. ViAggre is effectively a scalability technique that allows an ISP to partition the global routing table such that individual routers in the ISP's network only maintain a fraction of the routing table. We find that ISPs today can use ViAggre to shrink the routing table on their routers by an order of magnitude. Beyond performance results, I will detail the deployment of ViAggre and show that ViAggre can also yield faster route convergence.
