I have one question regarding the VLAN and trunk configuration.
currently, we have 7301 router with three interfaces. they are
GE 0/0 (VLan 1, vlan 2, vlan 3)
GE 0/1 (vlan 11, vlan 12, vlan 13)
for the GE 0/1, there is NO vlan 1 configuration. we are not tend to create vlan 1 for it.
any problem will be happen if there is no vlan 1 configuration in router but switch has for GE 0/1 interface?
does the trunk of GE 0/1 work porperly?
if we connect both GE 0/0 and GE 0/1 to the same switch (e.g. 2960G), can we config two trunks? (one for GE 0/0, other for GE0/1, they will swicth the packets to the right trunk)
can we enable the spanning tree for each trunk?
if there is not a good design, what is the better one?
We look forward to hearing from you
