The IS-IS routing protocol (Intermediate System to Intermediate
System, ISO 10589) requires reliable protocols at the link layer for
point-to-point links.  As a result, it does not use a three-way
handshake when establishing adjacencies on point-to-point media.
This paper defines a backward-compatible extension to the protocol
that provides for a three-way handshake.  It is fully interoperable
with systems that do not support the extension.

Additionally, the extension allows the robust operation of more than
256 point-to-point links on a single router.

This extension has been implemented by multiple router vendors; this
paper is provided to the Internet community in order to allow
interoperable implementations to be built by other vendors.  [STANDARDS TRACK]
