CIDR (Imp) Classless Interdomain Routing (CIDR) was introduced to improve both address space utilization and routing scalability in the Internet. It was needed because of the rapid growth of the Internet and growth of the IP routing tables held in the Internet routers. CIDR moves way from the traditional IP classes (Class A‚ Class B‚ Class C‚ and so on). In CIDR ‚ an IP network is

The Routing Information Protocol (RIP) is a distance-vector routing protocol‚ which employs the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops allowed for RIP is 15. This hop limit‚ however‚ also limits the size of networks that RIP can support. A hop count of 16 is considered an infinite distance and used to deprecate inaccessible‚ inoperable‚ or otherwise undesirable

2. Question : (TCO 1) Which routing principle is correct? Student Answer: If one router has certain information in its routing table‚ then all adjacent routers have the same information. Routing information about a path from one network to another implies routing information about the reverse‚ or return‚ path. Every router makes its routing decisions alone‚ based on the information it has in its routing table. Every router makes its routing decisions based on the information

K. Tamizharasu Professor‚ Dept. of Computer Science & Engg. Jayam College of Engineering & Technology Tamilnadu‚ India Hod_cse@jcet.ac.in Abstract—Quality-of-service (QoS) routing in an Ad-Hoc network is difficult because the network topology may change constantly and the available state information for routing is inherently imprecise. This paper proposes a method for multi-constrained feasible path selection for MANET. We introduce the composite function which allows OLSR to find the feasible

(IPv4 Routing Lookup) --> Goal is to decide on the following entities first. - Longest match / Lowest AD / Lowest Metric / Overlapping Routes(Multiple routes to the same destination in the routing table) / Policy Routing (Will override all the above steps) - Outgoing interface - Next-hop Step 2 - (IPv4 Switching Method) --> Goal is to move packets between interfaces. Load Balancing occurs at this stage. Even though we have multiple routes in the routing table‚

Introduction Assignment Develop a subnetting plan and implement it in the lab. Configure RIP as a routing protocol. Conditions NYEDGE1 is the hub router. The two remote office routers NYEDGE2 and NYWAN1 connect to NYEDGE1 through serial connections. Each router has a locally attached Ethernet network. The serial line data rates and DTE/DCE settings have already been configured on all three routers. You only need to assign the IP address to the interfaces. Notes The routers are connected directly
