Yeah, I feel border is more descriptive, it's on the border of your network. I usually hear access and core for the rest, where access connects to customers. I used to just say tower router, but lately we have 2 routers at some towers, one handling the backhaul links and the other handling the APs. Sometimes with a Preseem appliance between them.
Core router is a vague term, basically not border or access. Some people use it to mean a bigass router, usually at a NOC. More descriptive of how much traffic it carries or how much it cost, than its function. If you're not a border router, and you're not an access router, and you're not a CPE router, you're just a router. -----Original Message----- From: AF <af-boun...@af.afmug.com> On Behalf Of Seth Mattinen Sent: Wednesday, April 15, 2020 9:50 AM To: af@af.afmug.com Subject: Re: [AFMUG] Edge Router Options On 4/15/20 7:14 AM, Mike Hammett wrote: > Customer edge vs. provider edge I call them "border" routers; the first B in BGP literally is "border" and OSPF uses the term too. If someone says border router then I know they mean a router whose job is to exchange traffic between ASNs. Saying "edge" is too ambiguous for me. IMO if someone has to ask "edge of what" or add qualifiers then it's the wrong term. Terms like core, access, distribution (dist), border shouldn't need further explanation. As a bonus, one word descriptions are good for simple DNS. But that's just me and I never use the term "edge" since it's unclear, although it has recently become a buzzword like "cloud". -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
