Static Routes in Networking

traceroute = Verify path to destination network by determining hops show ip route = Displays the routing table and verifies route entries show ip interface brief = Displays the status of device interfaces show cdp neighbors = Displays a list of directly connected Cisco devices

Static Route = A manually configured route to a destination Default Static Route = Used when no specific route exists in the routing table Gateway of Last Resort = Used to forward packets when no other routes match Routing Table = A database of routes to various network destinations

Extended pings from R1 to PC3 fail = Indicates a potential routing issue Pings from R1 to R2 are successful = Indicates connectivity to R2 is established Pings from R1 to R3 are successful = Indicates connectivity to R3 is established R2 shows Gateway of last resort not set = Indicates misconfiguration in routing setup

<p>ARP = Resolves IP addresses to MAC addresses Routing Table = Determines the best path for packet delivery MAC Address = Identifies devices on the same local network Static Route = Provides a fixed path for data packets</p> Signup and view all the answers

<p>show ip route = To validate the routing paths in the network show cdp neighbors = To verify Layer 1 and 2 connectivity ping = To test reachability of a destination IP address traceroute = To analyze the path taken by packets to reach a destination</p> Signup and view all the answers

<p>Next-hop IP address = The address packet is sent to after routing Exit interface = The interface through which the packet leaves a device Decapsulation = Process of extracting data from the packet Encapsulation = Wrapping data in a new packet or frame</p> Signup and view all the answers

<p>ARP request = A packet asking for the MAC address of a specific IP address ARP reply = A packet responding with the MAC address of the requested IP address ARP table = A cache of IP to MAC address mappings Layer 2 MAC address = Hardware address used for communication on the local network</p> Signup and view all the answers

<p>ping = Verifies Layer 3 connectivity to a destination traceroute = Shows the path packets take to a destination show ip route = Displays the routing table show arp = Displays the ARP table and current mappings</p> Signup and view all the answers

<p>Static route = Manually configured route that does not change Dynamic route = Route learned from a routing protocol Default route = Route used when no other routes match Directly connected route = Route to a network directly attached to an interface</p> Signup and view all the answers

<p>Interface failure = Connectivity loss due to hardware issues Incorrect configuration = Connectivity issues caused by erroneous settings Oversaturated links = Performance degradation due to network congestion Service provider issues = Connectivity problems due to external provider failures</p> Signup and view all the answers

<p>Subnet mask = Determines which part of the IP address is the network Administrative distance = Value that determines the trustworthiness of a route Next-hop = Next device in the routing path to the destination Gateway of last resort = Default path for traffic with no specific route</p> Signup and view all the answers

<p>Sending ARP request = Broadcast to discover MAC address for an IP Receiving ARP reply = Obtaining the MAC address for the requested IP Building MAC address table = Recording the MAC addresses and their corresponding IPs Clearing ARP cache = Resetting stored IP to MAC address mappings</p> Signup and view all the answers

<p>Static Route = A fixed pathway for packet forwarding set by an administrator Default Static Route = Used when no specific route matches a destination IP address Routing Table = A data table that stores routes and next-hop information ARP Request = A message sent to find the MAC address associated with an IP address</p> Signup and view all the answers

<p>Encapsulation = Wrapping the packet inside a new frame for transmission Packet Forwarding = Sending the packet to the identified next-hop IP address ICMP Message = A network message sent back when a packet is dropped ARP Reply = Information sent by a host containing its MAC address</p> Signup and view all the answers

<p>ping = Checks connectivity to a host traceroute = Maps the route taken by packets to a destination show ip route = Displays the current routing table show ip interface brief = Provides a summary of interface statuses</p> Signup and view all the answers

<p>Directly Connected Route = A route to a network directly attached to a router interface Static Route Entry = Manually configured route set by an administrator Dynamic Route = Route learned and maintained by a routing protocol Default Route = Route used when no other route matches the destination</p> Signup and view all the answers

<p>Layer 2 = Data link layer that handles MAC addressing Layer 3 = Network layer that manages IP addressing and routing Layer 4 = Transport layer that oversees end-to-end communication Layer 1 = Physical layer that transmits raw bit streams</p> Signup and view all the answers

<p>Match with a static route = Router uses it to identify the next hop No route match = Router drops the packet and sends an ICMP message Match with directly connected interface = Searches ARP table for MAC address Route matched = Encapsulates and forwards packet out of the correct interface</p> Signup and view all the answers

<p>MAC Address = The hardware address used to identify devices on a local network IP Address = Identifies a device on a network and aids in routing NIC (Network Interface Card) = Hardware that connects a device to a network ARP Table = Stores IP-to-MAC address mappings for local devices</p> Signup and view all the answers

<p>Static Route Configuration = Manual setup of routing information Routing Protocols = Automatic methods to discover and manage routes Packet Encapsulation = Process of enclosing data in headers for transmission Network Layer Functions = Responsible for addressing, routing, and forwarding packets</p> Signup and view all the answers

<p>Router = Device that forwards packets between different networks Switch = Connects devices within the same network and forwards data based on MAC addresses Hub = Basic device that transmits data to all connected devices Bridge = Connects and filters traffic between two or more network segments</p> Signup and view all the answers

<p>Packet Dropping = No matching routing table entry Unreachable Host = Network connectivity issues or misconfigured routes ARP Timeout = Expired MAC address entry in the ARP table Routing Loop = Incorrect routing configurations causing endless forwarding of packets</p> Signup and view all the answers
