- E. BOM (Bill Of Materials)
正解：B、C、D、E
質問 # 54
BGP EVPN type 2 routes advertise MAC addresses of clients connected to VNIs on this VTEP. Other VTEPs use this information to populate the MAC address tables for the VLAN associated with the VNI.
VXLAN does not rely on MAC forwarding to establish connectivity
- A. The forwarding interface for the MAC address is the tunnel to the next hop VTEP
- B. The forwarding interface for the MAC address is the local interfaces
正解：A
質問 # 55
