Hi Tony, I am not looking for technical support, but looking for IETF's perspective regarding the system id in IS-IS.
As per the RFC 3784 there is no mention about any invalid value in a system id. Can you please confirm whether there is any such restriction to not to use a SYS ID of 0000.0000.0000 as per IETF standards ? If this mailing address is not appropriate for answering this query, can you suggest/redirect me to the correct team from IETF ? Thanks.
