B) Each device generates an Intra-Area-Prefix-LSA for each link
C) Link-LSA describes the link-local address and IPv6 prefix address on this link
D) Each device generates a Link-LSA for each link
2. MPLS supports carrying multiple network protocol services, including unicast IPv4 services, multicast IPv4 services, unicast IPv6 services, multicast IPv6 services, etc.
A) True
B) False
3. I-SPF and PRC can improve the convergence speed of IS-IS routes. They both recalculate only the changed routes. The difference is that PRC does not need to calculate the node path, but updates the route based on the SPT calculated by I-SPF.
A) True
B) False
4. In the BGP/MPLS IP VPN network shown in the figure, the administrator uses Hub- spoke networking to implement centralized control of VPN traffic at the Hub site. Which of the following RT value plans for each device is correct?
A) PE1 VPN1: IRT=100:1; ERT=100:1
PE2 VPN1: IRT=100:1; ERT=100:1
PE3 VPN1: IRT=100:1; ERT=100:1
B) PE1 VPN1: IRT=100:1; ERT=200:1
PE2 VPN1: IRT=100:1; ERT=200:1
PE3 VPN1: IRT=200:1; ERT=100:1
C) PE1 VPN1: IRT=100:1; ERT=200:1
PE2 VPN1: IRT=100:1; ERT=200:1
PE3 VPN in: IRT=100:1; VPN_out: ERT=200:1
D) PE1 VPN1: IRT=100:1; ERT=200:1
PE2 VPN1: IRT=100:1; ERT=200:1
PE3 VPN_in: IRT=200:1; VPN_out: ERT=100:1
5. As shown in the figure, CE1 sends VPN1 traffic to PE1. After receiving it, PE1 will forward the VPN traffic. Which of the following descriptions of this scenario are correct? (Multiple choice)
A) PE1 will use the LDP label corresponding to the Next_Hop address of the VPNv4 route as the outer label of the label message
B) PE1 will check the forwarding table corresponding to the VPN1 instance and obtain the Tunnel ID information
C) The interface on which PE1 receives the data is bound to the VPN1 instance.
D) PE1 will search for the corresponding private network label according to Tunnel 1D and push the label header into the message.
