Re: [bess] A question regarding Single-Active ES redundancy mode and DF election in RFC 7432

Krzysztof, You are right, the Port-Active draft uses a different technique for DF election. Regards, Sasha Office: +972-39266302 Cell: +972-549266302 Email: alexander.vainsht...@ecitele.com From: Krzysztof Szarkowicz [mailto:kszarkow...@gmail.com] Sent: Tuesday, September 4, 2018 3:04 PM

Re: [bess] A question regarding Single-Active ES redundancy mode and DF election in RFC 7432

Hi Sasha, Yes, the end result is sort of Port-Active from the draft you reference, although the tool set (DF election methodology) is not the same. Thanks, > On 2018-Sep-04, at 13:53, Alexander Vainshtein > wrote: > > Krzysztof, > Lots of thanks for your email. If I understand you

Re: [bess] A question regarding Single-Active ES redundancy mode and DF election in RFC 7432

Krzysztof, Lots of thanks for your email. If I understand you correctly, it actually replaces Single-Active Redundancy Mode with the Port-Active one as defined in the corresponding draft (it also uses the Preference-Based DF

Re: [bess] A question regarding Single-Active ES redundancy mode and DF election in RFC 7432

Hi Sasha, To use LAG in A/S mode on per VLAN basis, you can use ‘hack’, where you use preference-based DF election (draft-ietf-bess-evpn-pref-df) to ensure with the configuration that *all* VLANs on given ESI use PE1 as DF, and *all* VLANs on that ESI use PE2 as non-DF. Then, you need to have

Re: [bess] A question regarding Single-Active ES redundancy mode and DF election in RFC 7432

Ali, Lots of thanks for a prompt and detailed response. It matches my understanding of the situation with Single-Active Redundancy Mode of Ethernet Segments in EVPN. In particular, your confirmation that “You cannot use LAG to do active/standby on a per VLAN basis (aka EVPN single-active)” was

[bess] A question regarding Single-Active ES redundancy mode and DF election in RFC 7432

Ali and all, I have a question regarding one of the aspects of RFC 7432, namely operation of the default Designated Forwarder (DF) election process on an Ethernet Segment (ES) that operates in the Single-Active Redundancy Mode. RFC 7432 defines the Single-Active Redundancy Mode in Section 3 as
