CCNA has main focus on routing topics and switching topics, now a days if you are planning for the job in India and after some job experience if we are planning our job in abroad then easily can join anywhere. If will take example of routing protocols then are some division of routing protocol. Routing protocol divided in three parts, first is static routing, second is dynamic routing and last will be the default routing protocol. Static routing entry will be the manual, means for every remote network need to put the entry, if will discuss about the dynamic routing then again divided in many parts, first will be link state routing protocol also called LSRP, second will be the distance vector routing protocol also called DVRP and last is hybrid routing protocol also called HRP. Other routing protocol was default routing protocol. Default routing protocol has common entry of the network. We can run the command on router to configure the routing protocol. Take some example of command.



Command to run routing information protocol
Router rip
Network x.x.x.x
Network x.x.x.x

There are three version of rip, ripv1, ripv2 and ripng(routing information protocol next generation)

Command to run routing information protocol version 2
Router rip
Version 2
Network x.x.x.x
Network x.x.x.x

If you want to run ripng then can run on behalf of interfaces, not on behalf of the network.

If you want to run eigrp then command to configure eigrp will be
Router eigrp 100
Network x.x.x.x
Network x.x.x.x
No auto-summary

We need to run above command on directly connected network. But definitely command will change, if we want to run ipv6 along with any other routing protocol. There are some capacity of the router and its routing protocol. Rip has maximum limit upto 15th router. Means can run up to 15 router then after 15 router, network will be unreachable. Eigrp has maximum limit up to 255 but will be good for the successor path and feasible successor path. Eigrp will use autonomous system number. Autonomous system will be belong to 1 to 65536. Autonomous system will be like group of router present with single administrative entity.

If will talk about the OSPF then it is the open standard so can support any company router. Command to configure ospf is
Router ospf 100
Network x.x.x.x x.x.x.x area 0
Network x.x.x.x .x.x.x.x area 0

OSPF network has area, means group of router present with the area, one area can not communicate with the other area but yes we have feature to communicate with each other. One autonomous system can communicate with other autonomous system with the help of ASBR also called autonomous system border router. OSPF has no any limitation to run the network means maximum can support any router, maximum hop count will be unlimited.

BGP also can run, BGP is the internet largest protocol of routing. If we want to run routing protocol on router then need to run the command with beginning.

Suppose there are two routers, which is connected to each other then can run following commands, Suppose router1 can connected with router2 then can use below command
Enable
Configure Terminal
Interface fastethernet 0/0
Ip add 10.0.0.1 255.0.0.0
No shut
Int s0/0/0
Ip add 20.0.0.1 255.0.0.0
No shut
Clock rate 9600

If end device will connect to the router, then need to configure ip address to the computer, subnet mask to the computer, default gateway to the computer, need to configure dns ip address, alternate ip address to the network. We can also make router as a dhcp server. If will make router as a dhcp server then router will be behave like server. Router will be able to provide ip address to any device in the network, router has a capacity to provide ip address to the local area network also ip address to wide area network.
