After the packet leaves the router, it is sent to the receiving address that is contained in the header in its wrapper. It may not travel the same path as other packets that make up the message, however.

Implementing Distance-vector routing protocol?
First you must decide what specific protocol you want to use. Then you configure it on the individual routers. Example, with Cisco routers: Router(config)#router rip Router(config-router)#network 10.0.0.0. Router(config-router)#exit Additional commands may be required for optimization. Note: I use RIP for illustration purposes, but it is usually not the best option for routing.First you must decide what specific protocol you want to use.

What is the significance of packet size in a packet switching network?
The packet size is important because the network can then allow for flow control via a pre-determined 'window'. If there is a lot of PDUs travelling, the network can slow down the flow control, and reduce the packet window - so the receiving end can keep pace with the transmission - in an attempt to avoid a slowdown in network performance. However, in some instances the packet size can be set so that it cannot be fragmented.
What happens when electrons in conduction band loses its energy and falls to a hole in the valence band?
The energy leaves as either a photon or phonon.
Which three statement are true regarding the encapsulation an de-encapsulation of packets when traveling through a router?
** The router modifies the TTL field, decrementing it by one.** The router maintains the same source and destination IP.** The router changes the source physical address to the physical address of the exit interface
How do you forward ports on routers and when and why?
To forward ports on your router just login to your router's on-line interface. Port Fowarding is used when a program (lets use FileFind [not a real program]) requests a port the router doesn't understand. Lets say that FileFind requests port 130 on your router, but your router doesn't have a port 130. It does, however, have a 128. The port forwarding tells the request to port 130 to be routed through port 128.
What happens to ttl when a packet a router?
nothing
If a router receives a packet that is does not know how to forward what type of route must be configured on the router to prevent the router from dropping it?
Answering "If a router recieves a packet that is does not know how to foward what type of route must be configured on the router to prevent the router from dropping it?"
When the destination network is not listed in the routing table of a cisco router what are two possible options the router might take?
The router discards the packet. The router forwards the packet via the default route
What will happen if a router received a ICMP packet with TTL 0?
1.The router will discard the packet. 2.The router will send a time exceeded message to the source host.
What action will the router take for a packet that is destined for 192.168.1.5?
It will forward the packet to the default gateway.
What is the primary difference between router packet handling and application packet handling?
idfk
What would be the path of a packet sent from Router C to Router D if Router A was down?
taka the three routers
What happens to the priority of a packet marked with DSCP when it passes a router that only supports IP precedence?
Packets will be prioritized according to IP precedence.
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.
Receives a packet that is destined for 192.168.1.4 How will router treat the packet?
the router will enqueue the packet that is sent to the destination 192.168.1.4.and then that packet is sent on transmission media(cable).it checks every ip address that is holding the ip same as the destination ,if it reaches there then it deleiver it on that machine.
When a packet traverses a network each router is a...?
hop
When a packet traverses a network each router is a what?
hop
