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.
Which of the following statements about the configurations on PE 2 are true?
In PIM-DM, which of the following scenarios about sending Join messages is true?
On the MPLS Layer 3 VPN, PE security is key to the safety of the entire network. Which of the following security measures can be deployed on PEs?
Refer to the exhibit.
As shown in the figure, RTA belongs to AS 100 and has an EBGP
neighbor relationship with RTB. RTB, RTC, RTD, RTE, and RTF belong to AS 200.RTB, RTD, and RTE are assigned to AS65001, RTC to AS65002, and RTF to AS65003.
