Inter-VLAN routing is a major section in the BCMSN exam. Remember this exam is about multilayer switching, not just layer two switching. From Cisco's website:
"Implement Inter-VLAN routing.
Explain and configure Inter-VLAN routing (i.e., SVI and routed ports).
Explain and enable CEF operation.
Verify or troubleshoot InterVLAN routing configurations."
