There are smarter people than me here on the topic of BGP, but I believe load balancing via prepends is an inexact science. It's like the guy with the broom in curling, you can influence but not dictate the outcome.
You'd probably have better control advertising each subnet via just one of the upstream providers, but then you lose the advantage of redundant feeds. -----Original Message----- From: AF <[email protected]> On Behalf Of Matt Hoppes Sent: Thursday, November 12, 2020 5:45 PM To: [email protected] Subject: [AFMUG] Multiple carriers I have a situation where I can buy several 1 gigabit pipes from several top tier carriers relatively inexpensively. Or I can buy one fat pipe from one carrier. Say I need 4 gigabits of bandwidth and have four 1 gigabit pipes from 4 carriers running BGP, is there a best way to load balance these? Just AS pre-pend subsets on each carrier so certain subnets prefer one over another? Or is there a better way? -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
