EVPN Basic concepts. EVPN is a next-generation full-service bearer VPN solution. It subverts the traditional L2VPN’s mechanism of learning MAC addresses on the forwarding plane, introduces the control plane, and uses BGP extensions to transmit MAC address information. Based on MP-BGP, EVPN defines a series of new BGP EVPN route types that enable different sites

VRRP basic concepts. If association between VRRP and the uplink interface is not configured and the uplink interface or link of R1(master) in the VRRP group fails, the VRRP group cannot detect the fault and the master cannot forward traffic. In this case, the active/standby switchover cannot be performed, causing a traffic blackhole. Networking description.
