You mean, you want the whole world to know every time you have an igp flap? :-D This is not really considered to be good engineering practice. Lots of reasons why, but for a good starting point, google for: "bgp synchronization +site:nanog.org" Nick -- This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
