Ensure

All the Access switch ports are trunked.
Multilayer Interfaces are trunked.
Access switches have all the required l2 Vlan.
Multilayer should have all the SVI’s up.

Now with the above checks done, you should be able to ping any host in any vlan from any floor according to your connectivity

Hi Mahesh,

I have received your PKT file.
The CORE SWITCH doesnt have the VLAN configuration. Please add the VLAN and try to check.
I tested it and it is working

Thanks
