[bess] EVPN FRR Draft draft-ietf-bess-evpn-fast-reroute-00 question

[Nitsan Dolev <[e-mail]>]

Dear draft-ietf-bess-evpn-fast-reroute-00 co-authors,

Your help with the following question will be greatly appreciated,

In https://datatracker.ietf.org/doc/html/draft-ietf-bess-evpn-fast-reroute-00#name-requirements requirement #4 it is written that the solution MUST support EVPN Inter-subnet forwarding RFC9135 and EVPN IP-VRF-to-IP-VRF model described in section 4.4 of RFC9136.

Could you please clarify how the EVPN FRR solution specifically contribute to these use cases? (The RT-5 are all ESI advertised with all zeros)

Referring to all the related use cases (quoted below), one sees the benefit of EVPN FRR to SN1 which is multi-homed to BD-2 , but the EVPN FRR solution seems to provide NO benefit to the IP-VRF to IP-VRF use case solution per-se. (I.e. no reference

Your feedback will be greatly appreciated,
Nitsan Dolev
