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 !
