Routing Topology Views (03/01/2003)

This database encompasses daily 'sh ip bgp' formatted snapshots of the routing information base (RIB) for various PCH routers. The routing topology depicted herein encompasses routes that have been exchanged between PCH and local peers that have agreed to share routing topology data for reseach purposes. Note that the scope of routing topology data captured in this data set will change constantly, as network conditions vary, local peers grow and evolve, and new peers are configured. As of September 2016 daily snapshots were being collected on both IPv4 and IPv6 routes from a total of more than 100 collection sites.
