OSPF vs IS-IS

Hey all, Is there any reason to run IS-IS over OSPF in the SP core? Currently, we are running IS-IS but we are redesigning our core and now would be a good time to switch. I would like to switch to OSPF, mostly because of familiarity with OSPF over IS-IS. What does everyone think? -- CJ http://convergingontheedge.com <http://www.convergingontheedge.com>
