draft-ietf-rtgwg-mrt-frr-architecture-01IETF 84 RTGWG: 31 July Quick Status: MRT for IP/LDP Unicast Fast-Reroute Well understood and documented Plan for IGP Extensions: – Use a flag to show MRT support and indicate all associated information as a template. Keep it simple. Two forwarding options – LDP or IP-in-IP Associated algorithms all implemented and verified.

draft-ietf-rtgwg-mrt-frr-architecture-01IETF 84 RTGWG: 31 July Quick Status: MRT Algorithms Implementation of all MRT algorithms for modeling is done. Analysis underway to compare/contrast: – MRT alternates (slight variants of algorithm) – Not-via alternates – Optimal possible – Remote-LFA More topologies are better – anonymized is fine. Individualized results can be available.
