I am studying for ICND1 through CBTNuggets,
I recently watched videos on how to interact between different vlans using separate interfaces, sub-interfaces and Layer 3 Switching.
The first two worked fine for me, but the Layer 3 Switching is not working when i am pinging PC in one VLAN to the PC in other VLAN.
Suppose PC A is connected to Fa0/1 of Switcher and PC B is connected to Fa0/2 of Switcher.
Here is what I did,
I went to Switcher CLI, Went to Global Configuration mode,
created two vlans using commands,
# vlan 10 # vlan 20
Now I moved
fa0/0 port to
vlan 10 and
fa0/1 port to
I assigned IP addresses to PCs,
PC A (fa0/1):
PC B (fa0/2):
Now i went to the CLi of switcher and did this in Global mode,
# interface vlan 10 # ip address 10.1.1.1 255.255.255.0 # no shutdown # exit # interface vlan 20 # ip address 10.1.2.1 255.255.255.0 # no shutdown # exit
20 are up and running and all the ports are up too, but I couldn't be able to ping
PC B from
This is exactly what the guy did in the video and he managed to ping.
What did i miss ?
P.S: I also tried to erase arp tables but still couldn't be able to ping.
