How the routing is built ?

[Ranjith_Kumar]

Access switch cant communicate to another access switch(10.3.0.0 to 10.2.0.2)
but coresw1 is able to ping to core sw2

Here's a better view of that diagram.

Please do a "show configuration" on core sw1 and one of the access switches and provide the result...
