Re: OSPF vs IS-IS

Well up until not too long ago, to support IPv6 you would run OSPFv3 and for IPv4 you would run OSPFv2, making IS-IS 
more attractive, but that is no longer the case with support for IPv4 NLRI in OSPFv3.

The only reason in my opinion to run IS-IS rather than OSPF today is due to the fact that IS-IS is decoupled from IP 
making it less vulnerable to attacks.

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?
