Question 16 of 25

17. In MPLS VPN, in order to distinguish IPv4 prefixes that use the same address space, the RD value is added to the IPv4 address. Which of the following description is correct? (Multiple Choice)

After the PE receives the IPv4 route from the CE, it adds RD to the IPv4 route and converts it into a globally unique VPN-IPv4 route, and publishes it on the public network

RD can be used to control the release of VPN routing information

On the PE device, each VPN instance corresponds to an RD value. On the same PE device, the RD value must be unique in the Update message

DRD is encapsulated as an extended community attribute of BGP in the transmission process

Unknown unicast

Question 19 of 25

20. Regarding the basic forwarding process of MPL S, which of the following statement is wrong?

By default, the Egress node that supports PHP has a label value of 3 assigned to the penultimate hop node.

When an IP packet enters the MPLS domain, the MPLS border device inserts a new label between the packet's Layer 2 header and the IP header.

When the IP packet enters the MPLS domain, check whether the Tunel ID value corresponding to the destination IP address is 0x0. If the Tunel ID value is 0x0, then enter the MPLS forwarding process.

The transmitting node device will replace the existing label on the top of the stack (the outermost label) with the label allocated by the next hop device.

Question 24 of 25

25. Which of the following statements about inter-domain MPLS VPN is wrong? (Multiple Choice)

When only LDP is used for the public network label, for the cross-domain VPN-optionC scheme 2, Layer 3 labels are required in the packet forwarding process.

For the cross-domain VPN-OptionB method, an MP-eBGP neighbor relationship needs to be established between the two ASBRs.

For the cross-domain VPN-OptionA method, the route passed between the two ASBRs is a common IPv4 route.

For cross-domain VPN-OptionB, multiple interfaces (including sub-interfaces) are interconnected between two ASBR-PEs, each interface is associated with a VPN, and each ASBR PE treats the opposite end as a CE.
