Hi, can you review this simple sketch and give me your feedback?
Please see attached diagram for details. I also pasted question below.
Note that I have Vlan 5 network range on both sites. No IP address duplication exists.
Do you see any problem routing traffic from UserA to UserB?
I think it is strange that I am advertising same OSPF networks
On different sitesâ¦
Is routing going to interpret this as overlapping networks?
Hello Marlon, Mink
unfortunately 3750 don't support NAT the only multilayer switch that supports it is C6500.
I see your WAN links are GE ports you need to get a L2 service from your provider so that you can extend the vlan over it
the wan links can become L2 trunks carrying the shared vlan and backbone vlan(s) moving L3 config to SVI interfaces
802.1Q tunneling or EoMPLS can be the solutions for the provider side.
Hope to help
