TL;DR BGP wins in modern networks because it scales policy, not topology. Use communities to encode intent once and enforce it at the right boundaries; use iBGP with route reflection to distribute reachability cleanly; and reserve local-pref as your go-to knob for deterministic traffic engineering. For overlapping IPs (hello, mergers), communities plus a staged renumber/NATContinue reading “What is BGP?”

Bridging the Divide Between Developers and Network Engineers

TAC Connect Bot – Devvie Has a Sibling!

This article is written by Ben Story and originally appeared on his blog packitforwarding.com Recently I opened a TAC case through my Cisco Partner. In the initial automated response from Cisco TAC, I noticed something new. There was a link (https://tacconnect.cisco.com) that I had not seen before. Since it mentioned a bot, I figured whyContinue reading “TAC Connect Bot – Devvie Has a Sibling!”
