Deploying Networks by using IGPs (OSPF and EIGRP) Redistribution BASIX ONLY

This is my simple network but intuitive. Hear I will not explain too much but some lit on it.

Upper half of the network is configured with OSPF(R1, R2, R3).

Lower half is configured with EIGRP(R3, R4, R5). You might be thinking why R3 is common in this network configuration. Coz it is only router where redistribution taking place.

There is one thing more in R3 configuration. The cloud C1 which is connected to R3. What is the purpose of this. This is your assignment to understand. LOL!

Configuration of R3 is:

!
