What happens to a packet that has 172.16.0.0 16 as the best match in the routing table that is shown?
The packet is discarded.
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 device should be used for routing a packet to a remote network?
router
How does a dynamic route get into a routing table?
Routing is the process that direct a packet to choose an optimal path from source to destination. Routing is of two types static routing and dynamic routing . Dynamic routing is not done manually and uses a number of protocols , it is automatic.
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.
What type of convergence is a cell phone with an integrated navigation system is an example of?
there are three types of convergence namely, 1. device convergence - network switches supporting Ethernet packet, and internet packet (IP) routing and asynchronous transfer mode (ATM) 2. Application routing - integrated function 3. physical convergence - hardware therefor answer will be the application convergence for cell phone.
On a Cisco router x IP lists check source packet addresses while y IP access lists check for both source and destination packet addresses?
x -> standard y -> extended
What is the difference between direct and indirect routing?
When a system sends an IP packet to another system in a network, it is direct routing. When a system sends an IP packet to another system via a third system or more systems in a network, it is indirect outing.
What are networks on a local area network connected using?
Adopt RIPv2 which is not subject to packet flooding. Implement static routing. Implement a mix of routing protocols to contain the instabilities. Change the topology to a heirarchical design which puts each branch network in its own area.
What is packet forwarding?
Packet forwarding in simple terms is the forwarding of packets from one node to another from networking point of view. For example, a router or a switch. These networking devices make routing devices with the help of their routing tables and then select an outgoing interface. After that they make some changes in the packet header and push (forward) the packet to the selected interface. In case you don't know the meaning of packet. Packer is the smallest unit of size in networking. Different networks has different packet size. For example, in ATM Networks the packet size is of 53 Bytes.
What is multicast routing?
Multicast routing is done by sending one packet to several destinations (those destinations were announcing their interest by joining the multicast group). See [multicast].
