Question 7

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.

Question 8

RTA is a leaf router that directly connects to host A through interface GigabitEthernet 1/0/0. The

interface is configured as follows:

interface GigabitEthernet1/0/0 undo shutdown

ip address 192.168.4.2 255.255.255.0

pim sm igmp enable

igmp version 3igmp ssm-mapping enable igmp static-group 232.1.1.1

Configurations in the IGMP view are as follows:

igmp

ssm-mapping 232.1.1.0 255.255.255.0 10.10.1.1

ssm-mapping 232.1.2.0 255.255.255.0 10.10.1.1

Host A sends an IGMPv2 Report message to group 232.1.2.2. Which entry can be displayed by the display igmp ssm-mapping group command?

Question 9

Two BGP routes with the same prefix are received from two peers. The two routes have the same attributes except the next hop (NH1 and NH2).NH1 is iterated to the directly connected A and B, NH2 to directly connected C and D. If maximum load-balancing2 is configured in BGP and a router can be configured with a maximum of six paths for load balancing, how many paths does a forward information base (FIB) generate regarding this prefix?
