IS-IS and OSPF: Network Design Comparisons and ... - JANOG

Writing OSPF Code
• OSPF spec is an excellent implementation guide
• If followed to the letter, a working, if naïve,
implementation will likely result
• Spec is complex, but has almost no “why”
information; hence, other (potentially more scalable)
implementation approaches are at the implementer’s
own risk
• Barrier to entry in high-end router market
(you need to know the protocol intuitively)
