Hello Everyone, I have a question on Primary PE encountering a failure in EVPN multihoming in single active mode. RFC7432, section 14.1.1: <snip> If there is more than one backup PE for a given ES, the remote PE MUST use the primary PE's withdrawal of its set of Ethernet A-D per ES routes as a trigger to start flooding traffic for the associated MAC addresses (as long as flooding of unknown unicast packets is administratively allowed), as it is not possible to select a single backup PE. </snip> Questions: 1. Will the node in backup mode forward the packet to CE? 2. Will all the nodes in backup mode forward the packet before DF election? 3. If they forward, how is duplicate packets handled, in this case? Please help me anwere these questions. Thanks & Regards Jaikumar S
