SPRING WG, My co-authors and myself have presented a document in BESS WG which describes fast convergence in EVPN networks without relying on control plane actions. In the latest version SRV6 support was introduced.
https://datatracker.ietf.org/doc/draft-burdet-bess-evpn-fast-reroute/ The draft specifies two forwarding behaviours which must be implemented: * “Terminal disposition” to prevent loops, esp. in EVPN’s All-Active (MLAG) case * “DF-Bypass” to address the dropping of rerouted packets on blocked ports until control-plane catches up (BGP route withdraw) For SRV6, these are mapped to 2 proposed new behaviours (variants of existing behaviours) both taking optional Args - End.DT2U.Reroute : End.DT2U with Fast Reroute - End.DX2.Reroute : End.DX2 with Fast Reroute The authors would appreciate feedback and any comments on the SRV6 proposal contained in the document Regards, Luc André Luc André Burdet | Cisco | laburdet.i...@gmail.com | Tel: +1 613 254 4814
