Re: OSPF vs IS-IS

I'll go with that... And one other thing... Traditionally it has been easier for developers to add new features to 
IS-IS because of the structure and flexibility of TLVs, whereas OSPF required the design of entirely new LSA types to 
support similar capabilities... I guess this has become less of an issue over the last few years however...

Nonetheless, if I was building a greenfield network today, I would personally go with IS-IS, but that is largely 
because of my many years working with the protocol...

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.

how about simpler and more stable?
