The diagram above
Sw0 as the core, opens the IP routing, and configure the VLAN information 10, 30
Sw02 configuration vlan20, vlan30, top allied bottom allied ports are trunk
Sw01 configuration only vlan10, trunk cascade to sw02
Pc2 can be normal and gateway communication
In my understanding of trunk allows all vlan, why this topology pc1 and pc2 communication, and can't communicate with gateway?
Thank you,

This is not very normal, different SW02 didn't create vlans 10 above, so the packet from the PC - & gt; Sw01 is normal, but sw01 - sw02. Local vlan number is not forwarded.

Thank you for your reply,
Well, I also am such match, at ordinary times is need lower sw02 all vlan information, but just don't know where, so come to ask questions,

Main is don't understand: if sw02 f0/2 port to access port and configure the vlan so sure is discarded, not f/2 mouth now configured as a trunk, above the theory is that is can continue through to s0

Why can't you put no vlan forwarding, to clear up
