Hi,
why there is variation in the usage of IGP (ospf/is-is) among ISPs. why some ISPs are using IS-IS while others use OSPF ?
what are the issues related to this ? whether management issues(cost, maintanance) or design issues(scalability, security)?
please tell me in detail.
thank you.

Hi, you will find that certain "high-end" ISPs uses IS-IS. It is however over engineered for most users where OSPF is just fine. No detailed discussion is possible withing this scope, you might need to go some 15 years in the cisco-nsp lists for one.
