Can't communicate between Vlans (or even to any Vlan interface) from host machine using L3 switch.

Hi everyone, I'm a beginner in networking using GNS3 to simulate communication over Vlans. I've been stuck on this problem for a couple days...

I have two PC's, one with ip address 192.168.1.1/24 and default gateway 192.168.1.100.

The other is 192.168.2.3/24 with default gateway 192.168.2.100.

They are both connected to an L3 switch (Cisco 3640) that has two Vlans configured:VLan 1 : Ip address 192.168.1.100 / 24

VLan 2 : Ip address 192.168.2.100 / 24

Fast Ethernet port 0/0 is assigned to Vlan 1, and is connected to PC1.Fast Ethernet port 0/1 is assigned to Vlan 2, and is connected to PC2.

However, I can't ping PC2 from PC1 and vice versa. Even worse, I can't even ping either gateway from either PC (for ex. I can't ping 192.168.1.100 from PC1).

Any help is appreciated, thank you!
