Try changing the encapsulation on Sw1 Fa0/19 & Fa0/21 and Sw3 Fa0/19 &
Fa0/21 to Dot1Q and see if that works.
When configuring IEEE 802.1Q tunneling on an edge switch, you must use
IEEE 802.1Q trunk ports for sending packets into the service-provider
network. However, packets going through the core of the service-provider
network can be carried through IEEE 802.1Q trunks, ISL trunks, or
nontrunking links. When IEEE 802.1Q trunks are used in these core
switches, the native VLANs of the IEEE 802.1Q trunks must not match any
native VLAN of the nontrunking (tunneling) port on the same switch
because traffic on the native VLAN would not be tagged on the IEEE
802.1Q sending trunk port.

Do you have vlan 200 and 201 only on SW4?
