The following errata report has been submitted for RFC7432, "BGP MPLS-Based Ethernet VPN". -------------------------------------- You may review the report below and at: https://www.rfc-editor.org/errata/eid7758 -------------------------------------- Type: Technical Reported by: Pavel Mykhailyk <[email protected]> Section: 8.1.1 Original Text ------------- The Ethernet Segment route filtering MUST be done such that the Ethernet Segment route is imported only by the PEs that are multihomed to the same Ethernet segment Corrected Text -------------- The Ethernet Segment route filtering MUST be done such that the Ethernet Segment route is imported only by the PEs that are connected to same EVI Notes ----- In all text in context of evpn-multihoming term ES used for logical set of links - distributed PortChannel when CE use several links to different PEs as single aggregate link. But in section 8.1.1 term ES can't be used in same way, becouse ES routes must be distributed for all PE that hold same VLAN. For example PE1 and PE2 connected to CE1 with EVPN-MH PortChannel (ESI-1) and use VLAN 10, CE2 connected to PE3 and use VLAN 10 but not use any aggregation - not included to any ES. PE3 build mac table for CE1 mac and must use ESI-1 as next-hop, so it must apply ES route and not filter it, regardles of local connection to ES in terms of EVPN-MH PortChannel. So each PE connected to EVI import this route Instructions: ------------- This erratum is currently posted as "Reported". (If it is spam, it will be removed shortly by the RFC Production Center.)
