With a Cisco2821 router configured with subinterfaces, for example:
no ip address
ip address 10.10.100.1 255.255.255.0
ip address 10.10.200.1 255.255.255.0
If I connect port #1 of a D-Link unmanagable dumb switch to interface GigabitEthernet0/1 of the abovementioned router,
which vlan traffic will go thru port #1 of this switch? default vlan1, or vlan 100, or vlan 200? or all three vlans? Or can we control it and HOW?
Normally we would configure the port#1 of the switch (if it was managable) as a trunk, and let all three vlans thru. But in this case, the D-Link one is not managable.
Your knowledge sharing will be much appreciated.
