Can a packet be forwarded without a route?
No packet can be forwarded without a route. Whether the packet is originating in a host or being forwarded by an intermediary device, the device must have a route to identify where to forward the packet.
A device that operates at the network layer and can select the best route for a packet to travel over dissimilar networks is called a?
A router.
What Usage of no ip source-route?
I think ip source-route and policy routing very often get confused, but they are two very distinct things. Policy routing is a way of specifying routes to depend on various parameters, including perhaps the source IP address of a packet. It is a local policy applied at a router. ip source-route is something entirely different. It is a feature where the originator of an IP packet specifies, in that packet, which routers the packet must go through to reach its destination. The path is tagged onto the options field of the IP packet. The feature is very dangerous, and most NetAdmins disable it. I think the confusion comes about because of the words "source" and "route".
What was the route taken by people from eastern America to reach Oregon over land?
The land route was called the Oregon Trail.
Write difference in the form of a table between Ping and Trace Route command?
The Ping command sends a small packet of data to a destination IP address and waits for a response. It measures the time it takes for a packet to travel from the source to the destination. This command is typically used to check if a network device is online and responding to requests. On the other hand, the Trace Route command sends a series of packets to a destination IP address and tracks the route that each packet takes. It identifies each router or hop that a packet goes through on its way to the destination. This command can be used to diagnose network latency issues or identify where data is being lost. While the Ping command only provides information on the time it takes for a packet to reach the destination, the Trace Route command provides more detailed information on the network path and any delays or losses that occur along the way. In summary, both the Ping and Trace Route commands can be useful in troubleshooting network issues, but they serve different purposes. The Ping command is a simple tool for testing connectivity to a destination device, while the Trace Route command provides more detailed information on the network path and any issues that may be occurring.
When the destination network is not listed in the routing table of a cisco router what two possible actions the router might take?
The router discards the packet.The router forwards the packet out the interface indicated by the default route entry.
Which route will be preferred for this packet?
through the Fa0/1 interface
What device would you get if you took the features at layer 4 transport protocols and applied them to a switch?
All of the decisions needed to route a packet to a destination can be done with a layer 3 device (a router), or a layer 2 device (a switch) if you are on the same segment. There is really no need (from a pure functionality perspective) to ever unwrap a packet to that level until it is at the destination device. However there are plenty of reasons to unwrap packets do just this if we are looking at it from a security, or QOS perspective. So devices that will do things at layer 4 are going to be things like firewalls, proxies, network monitoring tools, packet shaping devices, and the actual destination device itself.
What are true statements about routes and their use?
--> If the destination network is directly connected, the router forwards the packet to the destination host. --> If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router. --> If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.
2 How do routers use the routing table to determine the best path to a destination network?
They check the number of hops a packet passes to reach the the destination. The router then uses the route with least number of Hops.
What is default routing?
A router is a device that decides where to send a data packet in order to get it one step closer to its destination, and then sends it there.In order to make this decision, the router looks at the destination address on the packet and then consults a list of rules programmed into the router by the person who set it up.If there is no explicit rule covering this packet - if the router hasn't been programmed with a rule on how to route packets to this particular destination - then the router send the packet to the default route.In other words, the default route is the destination that a packet is sent to if the router doesn't have instructions to send it somewhere else.As an example, consider a simple home router that connects your home network to the Internet. This router will have two routing rules - one for computers on your internal network, and a default route. The default route will send packets upstream to your ISP. So any packet that's not going to another computer at your house will always be sent out to the Internet.HTH,Gdunge
When forwarding a packet which route will the packet select?
First, routing is the process a router performs when making forwarding decisions for each packet arriving at the gateway interface. To forward a packet to a destination network, the router requires a route to that network. If a route to a destination network does not exist on the router, the packet will be forwarded to the default gateway. Now, the destination network can be a number of routers or hops away from the default gateway. If the router has an entry for the network in its routing table, it would only indicate the next-hop router to which the packet is to be forwarded to and not the exact route to the final router. To sum it up, the routing process uses a routing table to map the destination address to the next hop and then forwards the packet to the next-hop address.
