Abstract:
This document describes the benefits and main applications of sending
explicit fast notification (FN) packets to routers in an area. FN
packets are generated and processed in the dataplane, and a single FN
service can substitute existing OAM methods for remote failure
detection, such as a full mesh of multi-hop BFD session. The FN
service, therefore, decreases network overhead considerable. The main
application is fast reroute in pure IP and in IP/LDP-MPLS networks
called IPFRR-FN. The detour paths used when IPFRR-FN is active are in
most cases identical to those used after Interior Gateway Protocol
(IGP) convergence. The proposed mechanism can address all single
link, node, and SRLG failures in an area; moreover it is an efficient
solution to protect against BGP ASBR failures as well as VPN PE
router failures. IPFRR-FN can be a supplemental tool to provide FRR
when LFA cannot repair a failure case, while it can be a replacement
of existing ASBR/PE protection mechanisms by overcoming their
scalability and complexity issues.
