Informational [Page 2] RFC 6952 BGP, LDP, PCEP, and MSDP Analysis May 2013 1. Introduction In their "Report from the IAB Workshop on Unwanted Traffic March 9-10, 2006" [RFC4948], the Internet Architecture Board (IAB) described an attack on core routing infrastructure as an ideal attack that would inflict the greatest amount of damage and suggested steps to tighten the infrastructure against the attack. Four main steps were identified for that tightening: 1. Create secure mechanisms and practices for operating routers. 2. Clean up the Internet Routing Registry (IRR) repository, and secure both the database and the access, so that it can be usedShow full document text
