MPLS has the concept of forwarding equivalence class FEC. Which of the following descriptions about FEC are wrong? (Multiple choice)
- A . MPLS groups packets with the same forwarding processing method into one category, called FEC
- B . A forwarding equivalence class FEC assigns unique label values to all routers.
- C . Packets with the same FEC will be processed differently in the MPLS network
- D . The division of FEC is very flexible and can be any combination based on source address, destination address, source port, destination port, protocol type or VPN, etc.
The VXLAN centralized gateway centrally manages cross-subnet traffic. The deployment and management of the gateway are relatively simple, but because all terminals’ ARP entries need to be generated on the Layer 3 gateway, and the ARP entries on the Layer 3 gateway The specifications are limited, which is not conducive to scenarios with a large number of terminals.
- A . True
- B . False
