12. Which of the following devices is typically found near the Internet edge and offers security services for

135.46.63.10. In binary this is 10000111.00101110.00111111.00001010. The 135.46 preface points us to one of the Interfaces on the table, which both have a subnet mask of /22. The 22 MSB's of the binary are 10000111.00101110.00111100.00000000. Back to decimal, this is 135.46.60.0, which matches Interface 1, so it is routed there.

| Given a network topology of two or more routers and an IPv4 addressing scheme, implement static routing and confirm layer 3 connectivity.

DSDV is a proactive, hop-by-hop distance vector routing protocol where the routing table is maintained by each and every network node. The routing table consists of all the nodes required to reach destination also including the nodes to which packets are not sent. The routing table is kept updated at every time after each entry. In order to avoid the routing loops, DSDV uses the concept of sequence numbers to maintain the originality of route at all times. For the network in figure. 1 below, the routing table for node A can be seen in table. 1 which contains information about all possible paths reachable by node A, along with the next hop, number of hops and sequence number.

1. You have a network address of 132.66.0.0 and a subnet mask of 255.255.224.0. Which three of the following are valid host addresses for the subnet 132.66.160.0?

7. What is the purpose of the access layer? To connect together networking devices in a LAN

QUESTION 9: What IP address is assigned to Client-VM? Why is it assigned this particular address?

It is clear that if we use administrative distance to determine best routes, we can deal with the problem of different metrics. Nevertheless, administrative distance has the problem of routing loops, inefficient routing etc. These problems can be overcome by following the following configurations made:

The protocol I chose to write about is the Border Gateway Protocol because it is the main protocol used to operate the internet and recommended protocol for Cisco design certifications. The BGP protocol is an inter-autonomous protocol; which means it is for connecting separate large networks, such as a college network to a corporate network or the internet. Due to the large number of routes and connection this protocol must manage; it uses very many features, or attributes, to achieve this. Cisco defines these attributes as weight, local preference, multi-exit discriminator, origin, AS_path, next hop, and community. These attributes are used to discover networks and determine the best path to use for sending packets to those networks.

The routing table is a table that stores information about connected and remote networks, and it has three features. The three features of a routing table are 1) destination network, 2) next-hop and 3) metric. Packets are unable to be forwarded by the router without a route. If a route that is representing the destination network is not on the routing table, the packet will not be forwarded, and instead will be dropped. When the router is forwarding a packet, it uses the default route, which is used when the network is not represented by any other route in the routing table. On the other hand, static routing is the route that information can be manually configured on in the router. Static routes are reliable and the router does not need to use much overhead to process the packets that are being transferred viz static routing. However the static routes do not update automatically, and they have a higher continuing administrative cost. Dynamic routing was another routing type that was taught in chapter 5. Dynamic routing is when routers can also learn about routes automatically from other routers in the same internetwork Dynamic routing has higher router processing overhead but little administrative cost after initial setup.

On the WAN there are many more options and the best option in terms of reliability and speed is chosen.

Routing Protocol for Low-Power and Lossy Networks (RPL) is distance-vector protocol that builds a Destination Oriented Directed Acyclic Graph (DODAG) that has only one route from each leaf node to the root in which all the traffic from the node will be routed to. [35]

In AODV, the network is quiet until a connection is required. At that spot the network source that needs a transmission, broadcasts a request for connection. Other AODV intermediate nodes forward this message, and trace the node that they heard it from, create an detonation of temporary routes back to the source node. When a intermediate node receives such a message and already has a route to the target node, it sends a message backwards through a temporary route to the source node. The deprived node then begins using the route that has the least number of hops through other nodes. When a link

3. Distance Vector Routing: DV algorithm is distributed as it receives information of one or more nodes which are directly attached to it and distributes the same back to its neighbors. It is said to be asynchronous because as it does not need all of the nodes to operate in lockstep with one other. And it is iterative because as this process continues as long as there is no information to be exchanged between the neighbors.

Routing Information Protocol (RIP) is the simplest and commonly used routing protocol in IP networks. It makes use of distance vector routing technique and UDP for transport
