We are in the process of setting up an ipSec VPN between 2 locations. There are various encryption methods, algorythms and preshared keys to set up. Network1 will have access to specific VLANs on Network2 and vise versa.
The questions is:
Should side 1 have the exact same target VLANs configured as the ones advertised on side 2?
Or can for example side 2 advertise more VLANs than the actual destination ones configured on side 1?
