MED, in my experience, is not as commonly used. It is only useful if the peer does not add other preferences for your AS. I am seeing more and more companies that create a local preference automatically for peers who own a circuit from said company. > You need localpref to distribute outbound preference throughout a iBGP > network when you have multiple egress points across multiple border > routers. Correct. Only useful if you have multiple egress points as you say. > You mileage may vary. Prepending alone resolved my traffic engineering > needs without causing any bad side effects. While this used to be the primary method for traffic engineering, it is not really as useful as it used to be. It works very well in certain circumstances, but for the most part, it is really up to your peers to accept your prepending, and some are not doing that any longer. As you say, YMMV. -- ******************************************************************** * Butch Evans * Professional Network Consultation* * http://www.butchevans.com/ * Network Engineering * * http://www.wispa.org/ * Wired or Wireless Networks * * http://blog.butchevans.com/ * ImageStream, Mikrotik and MORE! * ******************************************************************** -------------------------------------------------------------------------------- WISPA Wants You!
