Actually there are other ways to influence inbound traffic other than specific routes or AS Prepending (i.e. MED). The problem with more specific routes is that some ISP's will drop routes that have a small subnet (i.e too specific) as a way to reduce there BGP tables. Here is the logic behind the decision to enter a BGP route into the actual routing table:

Or both? To influence your outbound traffic (send) you can simply add a filter rule that sets a higher cost to the path you do not wish to prefer. To influence your inbound traffic (receive) you can only try and influence how traffic comes to you via pre-pending your ASN or by announcing more specific routes out the path you prefer to use.

You can setup costs so that one provider is cheaper than the other, prepends for inbound etc. I would have to take a look really to go, here is the best way. .. ----------------------------------------------------------- Dennis Burgess, CCNA, A+, Mikrotik Certified Trainer WISPA Board Member - wispa.org Link Technologies, Inc -- Mikrotik & WISP Support Services WISPA Vendor Member Office: 314-735-0270 Website: http://www.linktechs.net LIVE On-Line Mikrotik Training Author of "Learn RouterOS" -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Sales Sent: Monday, October 05, 2009 11:09 AM To: WISPA General List Subject: Re: [WISPA] Bgp and mt Awesome but that wasn't much help lol.
