VLAN and IPSEC

When you have the same VLAN at 2 different sites. (The 2 sites have the SAME IP-subnet)

Is it possible to encrypt traffic using IPSEC between the 2 sites ?

I am also curious to see how this would work :)

If you have two IP overlapping networks, then you can use the following doc

Basically when you are linking two different sites using routers I would advise to use different subnets at both locations to simplify the routing tables.
