‚ÄčThis is IETF WG and I find such comment inappropriate. This discussion is
about extending BGP protocol and we all should be worried how to apply
effective policy on something which is being defined here.

So triggered by the above let me ask a very simple question. You and others
expressed very clearly that LCs should traverse N-ASes and be executed
somewhere remotely. Great.

Let's also assume that you talk to everyone in the path and convince them
to let your LC go through.

Question:

If you choose to inject LC in the format TARGET_ASN:ACTION:PARAMETER based
on what field is anyone in the BGP propagation path supposed to let's your
LCs go and stop all other 1000s of LCs injected by anyone else ?

Today RFC1997 don't go far as they have no way to apply per their
originator permit or deny statements.

Thx,
R.
