Hello, In reviewing our BGP routing policies last week, I realized that we are advertising our address space upstream in slightly different ways to our two upstream providers. For example, we might advertise a /21 to one provider and break that into two /22s when advertising it to the other. (The reason this was done was to help with traffic engineering--we'd prepend one of the /22s to help balance the traffic. Prepending the entire /21 might have been too much.) I'm just wondering if that's acceptable practice, or if we should advertise consistent prefixes between providers? Thanks, Ben -- <https://img.beta.newoldstamp.com/r/13887/p> Ben Logan Senior Network Engineer | Working Lead Wilkes Communications | RiverStreet Networks Address: 1400 River St Wilkesboro, NC 28697 Email: benlogan@myriverstreet.net Phone: 336-973-9075 Mobile: 336-452-8072 wilkes.net <https://www.wilkes.net> myriverstreet.net <https://www.myriverstreet.net> <https://img.beta.newoldstamp.com/r/13833/facebook> <https://img.beta.newoldstamp.com/r/13833/twitter> <https://img.beta.newoldstamp.com/r/13887/youtube> <https://img.beta.newoldstamp.com/r/13833/linkedin> <https://img.beta.newoldstamp.com/r/13833/instagram> This email transmission contains information which may be confidential and/or privileged.
