inter vlan routing - What am I doing wrong? |
|
|
I've been trying to get a test setup working to verify a
configuration using VLANS before implementing it full scale.
I'm glad I tried it first because it ISN'T working! :(
Diagram of the setup:

This all looks right, Both L2 and L3 should be working. ( but aren't :( )

L2 looks good, but L3 doesn't!?

Again, L2 looks good, but L3 doesn't!?
The only PC that seems to be able to be pinged is the *.10.2 machine.
