Hi,
I am trying to set up a small lab, where I have 2 PCs, 1 switch and 1 Router.
The 2 PCs are 192.168.10.1/24 (Vlan 10), D.G. 192.168.10.254/24 and, PC2: 192.168.20.1/24 (Vlan 20), D.G. 192.168.10.254/24.
Router has a subinterface fa0/0.20 for vlan 20, which PC2 is able to ping. However, ping from PC1 to it's D.G. 192.168.10.254 fails, which is an IP address on a physical interface fa0/0.
Trunking is enabled between between the switch and the router. Can somebody please advise what's wrong with the config?
Please see the the Router and Switch config below. Thank you.
