This document proposes a solution to use TCP for IS-IS flooding. The proposed solution is a relative simple extension to implement. IS-IS flooding over TCP brings BGP's property of scalable transport via TCP to Link-State protocols. This proposal defines a new TLV in point-to-point IIHs to signal the intent of a router to do flooding over TCP, and it defines a small header to encapsulate IS-IS PDUs in the TCP byte-stream.
