As shown in the figure, CE and CE 2 belong to VPN A, CE 3 and CE 4 belong to VPN B, VPN A and VPN B share the public network tunnels between border PE 1 and PE 2, and LDP tunnels are configured between PE 1 and PE 2. To isolate resources for VPN service data from PE 2 to PE 1, a unidirectional TE tunnel is configured t forward data from PE1. The QoS policy propagation though the border gateway protocol (QPPB) feature is configured on PE 2, and a QoS policy is defined when VPNs are bound to tunnel interfaces.
