Question to the Routing WG from MCI regarding routing setups. In
particular, as a global ISP using data from the RIPE database and
other registries.

- Inconsistant info in different registries
- Can't determine which is correct
- What to tell customers - where to store data
- US data in European database?
- Auto-generated router setups
- What is the position of RIPE / other areas

Shane Kerr, RIPE NCC: RIPE Routing Registry has no geographical
restrictions but provides authentication for local assignments only.
RIPE NCC can't require registration; only provides the tool.
Suggest RIPE document on how to use routing registry.

Routing Registry Consistency Checking (RRCC) - live bgp data (from RIS
project) compared against routing registry - 40% of RR objects not
announced. Tools to show those route objects so users can delete

Is anyone using auto-generated config from the routing registry
without manual checking? Input requested from wg.
