Explanation

Resolution: The DHCP Agent is a dynamically assigned IP address L3 Agent: Provides Layer 3 network functions and network address translation functions, allowing tenants' virtual machines to communicate with external networks. In a real-world deployment environment, multiple L3 Agents are typically required to run at the same time. DHCP Agent: Provides dynamic host configuration services to tenant networks, and is mainly used to dynamically assign IP addresses to virtual machines in tenant networks. Plug-in Agent: The plug-in agent needs to be deployed on each host running the hypervisor and provides local virtual switch configuration, depending on the specific plug-in type used. Common agents include ML2 plug-in agents, OpenSwitch agents, and Linux Bridge agents.
