Hey,
So there's a few reasons why its not working as intended I'll paste the configs below in case you want to apply the fix to get the result you want.
Step 1:
Missing IP within PC1s subnet on R1 - PC1 is on subnet 10.12.1.0/24, R1 only has one interface which is in subnet 10.10.1.0/24.
Conf t
interface eth0/0.12 (creating the subinterface with .12 as the VLAN ID)
Encapsulation Dot1Q 12 (enabling dot1q on sub interface, with 12 as the value for VLAN ID)
Ip address 10.12.1.254 (Allocating IP within PC1s subnet to the sub interface)
Step2: (can be skipped, isn't necessary for the lab tasks as we don't need to route between subnets)
PC1 isn't configured with a default gateway, we can confirm this with " ip route show | grep default"
On PC1:
sudo ip route add default via 10.12.1.254 dev eth0 -- This is creating the default gateway for PC1 to use.
Verify: ip route show | grep default
Step 3:
On SW1, E0/0 is not configured as a trunk.
On SW1:
conf t
interface eth0/0
switchport trunk encapsulation dot1q
switchport mode trunk
Verify: show int trunk
Hope I didn't miss anything out,
Hopefully that helps.
