OK I will bite - Yes, RIP everything and let'em all Rest-In-Peace. My 0.02cents about OP's question- "Scale" and Admin-headaches: IS-IS scales far better than OSPF. Admin-headaches - as your OSPF domain grows, do you want to continually re-design; create more areas? You definitely don't want 50k prefixes in your OSPF domain; in area 0 - try it and see how it works. Security& ease-of-deployment: IS-IS is inherently a l2 protocol used over IP and is IP-Version independant and I dare say, more secure at the protocol-level compared to any other flavor of IGP. As to why you see more OSPF than IS-IS(except of a few large one's States-side) is more of a history-lession. ./Randy ----- Original Message ----- From: Damien Burke <damien () supremebytes com> To: "nanog () nanog org" <nanog () nanog org> Cc: Sent: Thursday, October 22, 2015 12:12 PM Subject: RE: IGP choice Just use rip for *everything* Problem solved! -----Original Message----- From: NANOG [mailto:nanog-bounces () nanog org] On Behalf Of Mark Tinka Sent: Thursday, October 22, 2015 11:41 AM To: marcel.duregards () yahoo fr; nanog () nanog org Subject: Re: IGP choice On 22/Oct/15 18:57, marcel.duregards () yahoo fr wrote:
Hi everyone, Anybody from Yahoo to share experience on IGP choice ? IS-IS vs OSPF, why did you switch from one to the other, for what reason ? Same question could apply to other ISP, I'd like to heard some international ISP/carriers design choice, please.
The "everything must connect to Area 0" requirement of OSPF was limiting for me back in 2008. So we moved to IS-IS. Mark.
