The following errata report has been verified for RFC8584, "Framework for Ethernet VPN Designated Forwarder Election Extensibility".
-------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid7811 -------------------------------------- Status: Verified Type: Technical Reported by: Luc André Burdet <laburdet.i...@gmail.com> Date Reported: 2024-02-15 Verified by: Gunter Van de Velde (IESG) Section: .2 Original Text ------------- Where: o DF(V) is defined to be the address Si (index i) for which Weight(V, Es, Si) is the highest; 0 <= i < N-1. o BDF(V) is defined as that PE with address Sk for which the computed Weight is the next highest after the Weight of the DF. j is the running index from 0 to N-1; i and k are selected values. Corrected Text -------------- Where: o DF(V) is defined to be the address Si (index i) for which Weight(V, Es, Si) is the highest; 0 <= i <= N-1. o BDF(V) is defined as that PE with address Sk for which the computed Weight is the next highest after the Weight of the DF. j is the running index from 0 to N-1; i and k are selected values. Notes ----- An observation was made while reviewing EVPN Port-Active draft pointing to a possible algorithm errata in RFC8584 ; Basically, when evaluating the DF for HRW, > * DF(Es) is defined to be the address Si (index i) for which > Weight(Es, Si) is the highest; 0 <= i < N-1. Here, if N=1, no remotes: 0 <= i < 0 -- ERROR if N=2, 1 peer: 0 <= i < 1 -> possible values are only 0 meaning index 1 (the peer)’s weight is not considered. Logically, this should be 0 <= i <= N-1 or 0 <= i < N -------------------------------------- RFC8584 (draft-ietf-bess-evpn-df-election-framework-09) -------------------------------------- Title : Framework for Ethernet VPN Designated Forwarder Election Extensibility Publication Date : April 2019 Author(s) : J.
