Cisco Routing and common computer user

Birmingham Guy

hi,

Could somebody give me easy definition that how a common computer user get advantage of Cisco routing in daily life? When somebody configure RIP v2, EIGRP or OSPF. Then how common computer user get advantage of this configuration in Microsoft windows environment?

looking forward for daily life definition,

Gngogh

LOL.. if it wasnt for those protocols.. you wouldnt be able to surf the web, or surfing the web would be so slow that you would give up.

those protocols are dynamic routing protocols that help network technicians to establish routes to other networks.

Imagine if the technicians had to config static routes of all the routes in the world..

So yeah, they help the common user to surf the web, to send email, to access ftp server... and so one.

Dynamic Routing Protocols are used to avoid having to place and update static routes on every Layer 3 device. IGPs (Interior Gateway Protocols) make life alot easier. Without things like OSPF and EIGRP, you would have to alter static routes on multiple devices quite frequently [unless your network was relatively static]. RIP is mostly used for smaller networks [due to its inherent limitations]. OSPF and EIGRP are better for larger networks. EIGRP used to be Cisco Proprietary, so you would use OSPF if you had non-Cisco L3 devices.

Now, things could work without IGPs (RIP, OSPF, and EIGRP)...albeit with alot more work involved. But, without BGP (An Exterior Gateway Protocol or EGP), something to perform the same function, or 100% Hierarchical and Contiguous addressing...the Internet simply would not be possible. Could you imagine having to manually update static routes on millions of devices every time a new person or company connects to the internet. You couldn't update the routes fast enough.
