description:

This module provides Scapy layers for the Intermediate System to Intermediate System routing protocol as defined in RFC 1195.

Currently it (partially) supports the packaging/encoding requirements of the following RFCs: * RFC 1195 (only the TCP/IP related part) * RFC 3358 (optional checksums) * RFC 5301 (dynamic hostname extension) * RFC 5302 (domain-wide prefix distribution) * RFC 5303 (three-way handshake) * RFC 5304 (cryptographic authentication) * RFC 5308 (routing IPv6 with IS-IS) * RFC 8667 (IS-IS extensions for segment routing)

TODO:

  • packet relations (requests, responses)

  • support for recent RFCs: * RFC 5305 (traffic engineering) * RFC 5307 (support for G-MPLS) * RFC 5310 (generic cryptographic authentication) * RFC 5316 (inter-AS MPLS and G-MPLS TE)
