Experimental topology map:

Problem analysis: Because this topology is a three-layer device. The access switches (sw2, sw3) are forwarding devices. You can regard vlan 10 as a PC as a whole, and similarly, vlan 20 is also a PC. So it can be simplified to a three-layer switch and two pc connections. Simplified can be regarded as a router and two pcs.
Experiment goal:
The network can communicate across different VLANs. That is, pc7ping to pc10. It can communicate under the same vlan. And under the same vlan. Can not go through the aggregation switch. But directly through the access switch.
Reason for implementation:
The reason why it can communicate across VLANs is that the aggregation switch can forward data packets to another VLAN.
Similarly, no configuration is required under vlan 10. Because access switch
Supplement:
The Layer 2 switch will not send arp packets to different network segments, and will only communicate within the same network segment.
A network host and B network host are not in the same network segment, assuming
A network address segment is: 192.168.10.0/24;
B network address segment is: 192.168.20.0/24;
A network host X (192.168.10.10/24) if you want to directly communicate with B network host Y (192.168.20.10/24),
X will not directly send an ARP request packet to request the MAC address of Y, but will request the MAC address of the gateway of the network segment (A network) where the X host is located. The network card will directly inform the system: "Destination host unreachable." and give up the communication.
So even if the ports of the switch are in the same broadcast domain, there is no need to worry about the communication between the A network and the B network.

In this topic, you only need to configure the ip address, gateway, and mask of sw1 and pc. The access switch does not require any configuration. The configuration of the pc is shown in the topology diagram.

Is it possible to configure two PCs with different network segments under vlan 10. E.g
pc1：192.168.100.10/24
pc2：192.168.200.20/24
pc3：192.168.100.30/24
pc4：192.168.200.40/24
to realize the intercommunication between pc and pc
No
because when dividing vlan. The vlanif address at the port has been divided.
When pc2 accesses pc3, pc2 cannot forward packets through the aggregation switch. The gateway cannot be found at all.
is the vlan 10 currently allocated at g0/0/1
followed by vlanif. vlanif is not the ip address allocated at the interface. But the ip allocated on the vlan.
That means the gateway in vlan 10 is 192.168.100.1. Only the IP in this network segment can be forwarded.

Through the analysis of the packet capture at e0/0/2

Ping packets under the same vlan
will not go through the aggregation switch sw1
