Hi Nuriani, hi lir-wg, hi routing-wg,

i am starting to write a BCP / guideline document covering this issue. 
I would appreciate the help of other network operators, since i do not 
know all network operators directly.

The version(s) of the document can be accessed at www.lambda-solutions.de/bcp/
I already did a first draft covering the items which will be in the document
but would appreciate if i could get help from the different operators.
I would like to have input from the current practice from:

	- Level3
	- UUnet
	- Sprint
	- C&W
	- Ebone

(which i would declare as "major transit provider" because i don't like the
terminology about "tier-xyz")

and also from the other important downstream isps, how they handle this issues.
Also some information from ripe would be handy, if they ACK issue PA assignments
or do PI requests for this kind of issue.
