A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Loop-Free IP Fast Reroute Using Local and Remote LFAPs Author(s) : I. Hokelek Filename : draft-hokelek-rlfap-01.txt Pages : 0 Date : 2008-2-26 This draft describes a new loop-free IP fast reroute mechanism which enhances the IP Fast-ReRoute (IPFRR) [1,15] by introducing the concept of pre-computed remote Loop-Free Alternate Paths (rLFAPs) on top of the IPFRR local LFAP. In rLFAP, a router which is adjacent to the failed resource switches over to pre-computed LFAPs, if they exist, immediately after failure detection. Multi-hop neighbors (MNBs) are notified about this remote failure as quickly as possible using fast failure notification mechanism. Upon receipt of failure information, MNBs activate their pre-computed remote LFAPs that they maintain for protecting against remote failures within their multi-hop neighborhoods. In the worst case, where IPFRR results in forming micro-loops, rLFAP completely prevents micro-loops for single link failures and quickly converges to a loop-free path in case of multiple link failures.
