Routers use routing protocol (rip,eirgp,ospf etc.) to communicate with others. We can think that protocols are languages of routers. There may be many different networks on router and the router can use different routing protocol for different routers, it depends on network topology. If we want to router share its network information that it learned due to different routing protocol from different router, we have to use redistribution. To understand easily what I mean, look at the topology below. Router-1 uses rip v2 protocol when it communicates with router-2 and it uses eirgp protocol when it communicate router-0 on this topology. Router-1 need to use eirgp redistribution on rip for sharing network 10.10.20.0/30 with router-2. In addition, router-1 need to use rip redistribution on eirgp for sharing network 10.10.10.0/30 with router-1. Today, I will show you redistribution between eirgp and rip v2 protocols.
Now, if you understand why we need to redistribution, you can watch this video to learn configuration of redistribution between eirgp and rip v2 protocols.
Note: Knowledge is to understand
To understand who you are.If you know not who you are
What's the use of learning?
