Re: correct Error code

Brian, 
 RFC 4666 mentions Invalid Routing Context to be sent if a message is received from a peer with an invalid(unconfigured) Routing Context value. Your analysis makes me think that only unconfigured RC is to be treated as Invalid. Isnt the RC invalid in the example mentioned below.
 
 I may be wrong but sending ERR management Locked message somehow does not inform the peer that there is something wrong at its end. IMHO, "Invalid Routing Context" seems like an appropriate message, since the RC is INVALID in this case. The RC being configured does not take away from the fact that it is invalid.
 
 Does RFC 4666 state anywhere that only unconfigured RC's are to be treated as Invalid? I mean, does it define Invalid RC in any sense.

Well....  RFC 4666 says:

   The "Invalid Routing Context" error is sent if a message is received
   from a peer with an invalid (unconfigured) Routing Context value.
   For this error, the invalid Routing Context(s) MUST be included in
   the Error message.

In this case, the Routing Context value is configured.

Also, RFC 4666 says:

   - If the RC parameter is included in the ASP Active message and the
     corresponding RK has been previously defined (by either static
     configuration or dynamic registration), the peer node MUST respond
     with an ASP Active Ack message.  If for any local reason (e.g.,
     management lockout) the SGP responds to an ASP Active message with
     an Error message with reason "Refused Management Blocking".

So, in this case, the corresponding RK is configured by static configuration
and the SGP has two choices: respond with ASP Active Ack, or response with
ERR("Refused Management Blocking").  If the SGP does not wish to permit the
ASP to activate for the AS, the proper error code is "Refused Management
Blocking".
