Name: draft-hao-bess-evpn-df-handshaking Revision: 00 Title: Handshaking mechanism for DF election Document date: 2015-02-06 Group: Individual Submission Pages: 9 URL: http://www.ietf.org/internet-drafts/draft-hao-bess-evpn-df-handshaking-00.txt Status: https://datatracker.ietf.org/doc/draft-hao-bess-evpn-df-handshaking/ Htmlized: http://tools.ietf.org/html/draft-hao-bess-evpn-df-handshaking-00 Abstract: In [EVPN], DF election process on each PE connecting to same ESI is triggered by independent timer expiring, DF and non-DF PEs can't ensure that unblocking and blocking action take effect at the same time, sometimes long time traffic disruption will occur. Handshaking mechanism for DF election is introduced in this draft, it can effectively reduce traffic disruption and avoid potential issues of packet duplication and loop in all-active access scenario. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
