default, a vro does not forward broadcast traffic. Therefore, it can be used to separate broadcast domains. Creating a broadcast domain with a vro reduces the broadcast traffic and provides more bandwidth for unicast communication. Each vro port is connected to a separate network, broadcast traffic is limited to the lan cidr block where the broadcast is sent. However, there are usually few vro network interfaces (

confusion, and so on. 4. About the AddressIn the TCP/IP protocol, two pieces of information are used to locate a specified program: Internet address and port number, range 1-65535. The former is used by the IP protocol, which is parsed by the transport Protocol (TCP/UDP).Internet addresses are made up of binary numbers in two forms: IPv4 (32-bit) and IPV6 (128-bit). For ease of use, the two versions of the IP protocol have different representati
