As shown in the figure. CE 1 and CE 3 belong to VPN-A, and CE 2 CE 2 4 belong to VPN-B VPN-target VPN-A is 111:1 and that of VPN-B is 222:2 users on different VPNs are not allowed to access each other.
Configuration principles are as follows:
On the backbone network VPNs are not connected to a CE, VPN instance need to be configured on the PE, and an interface on the PE for connecting to the CE must be bounded to a VPN instance. After binding an interface to a VPN instance, you must configure the IP address of the interface Between
PEs, IS-IS is configured for PE interworking. MPLS basic capabilities and MPLS LDP are configured for MPLS LSP establishment, and MP-IBGP is configured for VPN route exchange.
How to enable CE 1 to learn routes from AS 64430?
- A . Import IS-IS 200 routes in IS-IS process 100
- B . Import IS-IS 100 routes in IS-IS process 100
- C . Import BGP routes in IS-IS process 100
- D . Import BGP routes in IS-IS process 200

Suppose the preceding policy is retained. Apply inbound policies on RTC. RTD and RTE so that the values of the preferred-value attribute of route 1.1.1.132 are 50.40 and 30 respectively .
Which route will RTB prefer?
- A . RTC, RTC, RTE, RTC, RTE
- B . RTC, RTD, RTD, RTE. RTE
- C . RTC, RTC, RTD, RTC, RTE
- D . RTC, RTC, RTD, RTE, RTE
Exhibit:
As shown in the figure, RTA and have one BGP session. To detect fault fast, the BFD for BGP feature needs to be configured on RTA and RTB.
BGP-related configurations are as follows:
The only Ethernet link between RTA and RTB becomes faulty when the BGP neighbor session is in ESTABLISHED state and the BFD session is in the UP state .
Which statements is true? (Note: BFD works in asynchronous mode)
- A . RTA detect the fault faster than RTB.
- B . The BGP session between RTA and RTB is interrupted when the BGP hold time (time duration is 180s by default) express.
- C . RTB detect the fault faster than RTA.
- D . RTA and RTB detect the fault simultaneously.
Exhibit:
As shown in the figure, virtual private LAN service (VPLS) is enabled on routers PE 1 and PE 2. CEs are connected to PEs through QinQ and PC A and PC B are connected to the two CEs. The two PCs belong to the same VPN and can communicate with each other properly .
Which of the following statements about the communication process when you ping PC B from PC A are true?
- A . PE 1 receives packets with a VLAN tag from CE 1 and adds a VLAN tag to these packets.
- B . If the penultimate hop popping (PHP) feature of MPLS is enabled on PEs, a packet received by PE 2 from a P router has two VLAN tags one MPLS label.
- C . PE 1 add two MPLS labels to a packet before sending the packet to a router.
- D . A packet received by CE 2 from PE 2 has two VLAN tags CE 2 removed the outer tab and forwards the packets to PC B based on the inner tag
Exhibit:
As shown in the figure, Super VLAN is enabled on SWA (a LAN switch).
The Super VLAN configuration is as follows:
Which of the following specifics the time order in which the preceding debugging information is generated?
- A . 3–4–1–2
- B . 1–2–3–4
- C . 1–4–2–3
- D . 3–2–1–4
Configure VRFs and relevant policies on a PE as follows:
If a route is imported to the routing table of VRF 1, which VRF can the route match?
- A . vrf4
- B . vrf3
- C . vrf2
Which statement about the configuration of route target (RT) and route distinguisher (RD) is true?
- A . If routes need to exchange between two VPNs, the value of import RT of one VPN must be partially the same as Export RT of the other VPN.
- B . RD and RT of a VPN instance cannot be the same as those of another VPN instance on the same
PE. - C . If routers need to exchanged two VPNs, the value of import RT of one of the same as that of RT of the other VPN.
- D . Two instances of a VPN share an RT.
Which statement about the Hub s MPLS VPN networking is false?
- A . The Hub PE can receive the VPN_IPv4 routes advertised by all Spoke PEs.
- B . When an MP-IBGB neighbor relationship is established between two spoke PEs, the value of the Import VPN Target attribute of one Spoke PE can be the same as tat of the Export VPN Target attribute of the other Spoke PE.
- C . The Hub PE advertises the routes learned from one Spoke PE to other Spoke PEs. Therefore, Spoke sites can access other through the Hub site.
- D . All Spoke PEs can receive the VPN-IPv4 routes advertised by the Hub PE.
