The purpose of this panel is to discuss desired route filtering capabilities of services providers (both panel members and attendees), as well as to express perceived shortcomings with the different components required to effectively support large numbers of prefixes (e.g., routing registries, vendor support, management and provisioning, etc.). It's relatively well understood that service providers need to employ customer ingress prefix filters. However, the feasibility and usefulness of inter-provider filters has yet to be realized. Once fully supported, these filters may potentially be used for other applications as well.
