I have 4 sites with overlapping address (192.168.1.x)/24 under VLAN 10 SVI and it is a secondary range.
They should be able to talk to primary range and other VLANs at the site without any restriction via inter vlan routing.,
This secondary subnet is not advertised over WAN.
SVI for VLAN 10 is created on the 3750 core switch.
We want a solution that would let this all devices in 192.168.x.x to talk to the HQ temporarily.
I think about NAT on SVI as a solution.
Do you have any other good recommendation?
Can we do nat on SVI using route-map on 3750? What kind of license or IOS version is required?
