CCNA: Address Resolution Protocol (ARP) In this article, we will talk about ARP that maps the layer 3 address to the layer 2 MAC address. This is similar to Address Resolution Protocol, which maps layer 3 IP addresses to the layer MAC addresses. CCNA RnS Article #28: Why Spanning Tree Protocol? IP address.

An administrator configures default gateway configuration manually while configuring the system on the LAN or it can be configured automatically using the DHCP protocol. Or it is built automatically by using the different routing protocols such as OSPF, BGP, RIP etc. CCNA RnS Article #28: Why Spanning Tree Protocol?

Send these pings using the Internet Control Message Protocol (ICMP) or TCP to one or any of the devices you believe to be involved. In some cases if ICMP is filtered, you can usually switch to TCP (Transmission Control Protocol) and use tcping, telnet, or another TCP-based method to check for reachability.
