  "abstract": "The IS-IS routing protocol (ISO 10589) requires reliable protocols at\r\nthe link layer for point-to-point links. As a result, it does not use\r\na three-way handshake when establishing adjacencies on point-to-point\r\nmedia. This paper defines an backward-compatible extension to the\r\nprotocol that provides for a three-way handshake. It is fully\r\ninteroperable with systems that do not support the extension.\r\nAdditionally, the extension allows the robust operation of more than\r\n256 point-to-point links on a single router.\r\nThis extension has been implemented by multiple router vendors;  this\r\npaper is provided as information to the Internet community in order\r\nto allow interoperable implementations to be built by other vendors.",
