Hi Stephane, /chair hat off
IMO in disjoined topologies one should have flexibility to enable/disable LFA as per AF. Cheers, Jeff From: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Date: Thursday, February 19, 2015 at 11:21 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: LFA manageability : per AF config => feedback required Hi Folks, As you know, LFA manageability draft is in final phasis … The current document states per AF granularity activation as a SHOULD. “ 5.1<https://tools.ietf.org/html/draft-ietf-rtgwg-lfa-manageability-07#section-5.1>. LFA enabling/disabling scope The granularity of LFA activation should be controlled (as alternate nexthop consume memory in forwarding plane). An implementation of LFA SHOULD allow its activation with the following criteria: o Per address-family : ipv4 unicast, ipv6 unicast, LDP IPv4 unicast, LDP IPv6 unicast ... o Per routing context : VRF, virtual/logical router, global routing table, ... “ In the framework of ISIS/OSPF yang modelization, we are challenging this statement, do we really need to force implementation to support this “per AF” granularity ? Please provide as soon as possible your feedback on this and also provide clear drivers to support or not per AF activation of LFA. Thanks for your help !
