Which of the following statements about the Dynamic Host Configuration Protocol (DHCP) snooping function are true?

Exhibit.

The preceding information shows the configurations of Ethernet 6/1/1 and ensure created based on received
IGMPv2 Report messages. Which action does Ethernet 6/1/1 after receiving Leave messages for group
224.1.2.3?

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.
