Detailed explanation-1: -Layer 2 protocols or network L2 protocols are a list of communication protocols used by Layer 2 devices (such as network interface cards (NIC), switches, multiport bridges, etc.) to transfer data in a wide area network, or between one node to another in a local area network.
Detailed explanation-2: -The show interfaces command displays statistics for the network interfaces. The resulting display on the Cisco 7200 series routers shows the interface processors in slot order. If you add interface processors after booting the system, they will appear at the end of the list, in the order in which they were inserted.
Detailed explanation-3: -To configure layer 2 ports as layer 3 you have to give a command “no switchport” at interface config mode and assign an ip address and no shut. To configure routing protocol you have to configure it the way you do on normal routers.
