Here is my scenario:
3 sites: 192.168.3.x, 192.168.4.x & 192.168.5.x (site to site )
sites 3.x and 4.x currently has a tunnel between them. site, 4.x only tunnel into site 5.x.
note: there is no tunnel between 3.x and 5.x
Is there a way to make devices in site 5.x communicate with devices in site 3.x without having to create a separate tunnel ? and what you recommending?
