Ambiguous QinQ termination configuration example
Network requirements
As shown in
, Host A, Host B, and Host C belong to VLAN 11, VLAN 12, and VLAN 13,
respectively. The server group is connected to Switch C. QinQ is enabled on Switch B.
Configure QinQ termination, so that Host A, Host B, and Host C can communicate with the server group.
