Two vendors, two OSPFs. Does this come as a surprise to you? No? Welcome to the club.
I was neglecting this blog for a while, more than 2 years actually. Well, things changed in my personal life, but this is out of scope for this whiteboard. Let me stick to networking stuff here.
Moving to a design verification team of a vendor, where my daily job is to make sure that things work as designed, put me to another stand point. It is not about looking for bugs and bad implementation, it is about looking deeply into networking fundamentals and understanding the solutions. And there are many. People think their own ways and you can't say they are wrong. Well, some solutions work better than others, some are more robust and less prone to errors and, yes, some are bad. But — there are many ways :-).
I'm currently looking into OSPF implementations from a few vendors and I might report some findings here. You might be surprised that some details in OSPF can be understood in different ways by different vendors. Or not?
