Abstract

Intermediate System to Intermediate System (IS-IS) [ISO10589] has been adopted widely in various Layer 2 / Layer 3 routing and switching deployments of data centers and for critical business operations. Its flexibility and scalability make it well suited for the rapid development of new data center infrastructures. Also, while technologies such as Software-Defined Networking (SDN) may improve network management and enable new applications, their use has an effect on the security requirements of the routing infrastructure.
