 * Any Other Business

	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
	them.

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