the meaning of IGRP process

Multiple IGRP processes can be configured on the same router, but for routers to exchange information successfully, routers have to use same process number.

I also heard that RIP could be configured with one process on each router. Then what is th point to configure multiple IGRP processes on a router?

You could possibly limit the routers that your want participating in a particular IGRP process to speed up convergence and seperate the network into logical "areas". Maybe? Hmm....

The IGRP process is the logical routing domain. So for example IGRP 1 would be one process and IGRP 2 would be a separate process.

You can use separate processes on a router if you do not want the routes shared between them.
