The curriculum also helps students develop workforce readiness skills and builds a foundation for success in networking-related careers and degree programs. CCNA Routing and Switching teaches comprehensive networking concepts and skills, from network applications to the protocols and services provided to those applications by the lower layers of the network. Students will progress from basic networking to more complex enterprise and theoretical networking models later in the curriculum. Market research and global employers have consistently indicated that the skills gap for general networking skills is shrinking, while the skills gap for essential networking technologies such as security, voice, and wireless, and for emerging technologies such as data center, cloud, and video, is growing. Students may choose to pursue Cisco advanced technology certifications after achieving the prerequisite CCENT certification. Routing Concepts. Static Routing. Dynamic Routing. Introduction to Switched Networks. Switch Configuration. Access Control Lists. NAT for IPv4. Device Discovery, Management, and Maintenance. LAN Design. Scaling VLANs. Multiarea OSPF.

This protocol is an evolution of an earlier Cisco protocol called IGRP, which is now considered obsolete. EIGRP calculates its metric by using bandwidth, delay, reliability and load. By default, only bandwidth and delay are used when calulating metric, while reliability and load are set to zero. EIGPR uses the concept of autonomous systems. Each router inside an autonomous system must have the same autonomous system number configured, otherwise routers will not become neighbors. To establish a neighbor relationships, routers send hello packets every couple of seconds. Hello packets are sent to the multicast address of The following fields in a hello packet must be the identical in order for routers to become neighbors:. Routers send hello packets every couple of seconds to ensure that the neighbor relationship is still active. By default, routers considers the neighbor to be down after a hold-down timer has expired. Hold-down timer is, by default, three times the hello interval. R2 is directly connected to the subnet When the subnet is advertised to R1, R2 informs R1 that its metric to reach R1 receives the update and adds the metric to the neighbor to the reported distance. A successor is the route with the best metric to reach a destination. That route is stored in the routing table. A feasible successor is a backup path to reach that same destination that can be used immediately if the successor route fails. These backup routes are stored in the topology table. R1 has two paths to reach the subnet R1 stores that route in the topology table. This route can be immediately used if the primary route fails. EIGRP toplogy table contains all learned routes to a destination. The table holds all routes received from a neighbor, successors and feasible successors for every route, and interfaces on which updates were received. Best routes the successors from the topology table are stored in the routing table. Feasible successors are only stored in the topology table and can be used immediately if the primary route fails. Consider the following network topology. EIGRP is running on all three routers. Routers R2 and R3 both connect to the subnet R1 receives both updates and calulates the best route. The best path goes through R2, so R1 stores that route in the routing table.

M Kurukshetra The Cisco Certified Network Associate certification is popular certification course that covers skills necessary to administer Cisco devices on small or medium-sized networks. Examinees may take the exams separately or the single CCNA composite exam. It uses distance vector algorithm which mathematically compares routes to identify the best path to be chosen for a particular destination address. Rip sends routing update messages at regular interval of time and also when the network topology changes. The maximum hop count for rip is 15 and the Administrative Distance AD is Router updates its routing table to reflect the new changes. Frame Relay follows principle of packet-switched technology. Packet- switched networks allow dynamically share the network medium and the available bandwidth to the end to end stations ACLs are lists of conditions that are applied to traffic traveling across a router's interface. These lists tell the router what types of packets to accept or deny. Acceptance and denial can be based on specified conditions. ACLs can be configured at the router to control access to a network or subnet. ACLs must be defined on a per-protocol, per direction, or per port basis. There are three types of ACLs 1. Standard 2. Extended 3. Named 1. Limit network traffic and increase network performance. Provide traffic flow control. Provide a basic level of security for network access. Decide which types of traffic are forwarded or blocked at the router interfaces. For example: Permit e-mail traffic to be routed, but block all telnet traffic.
