If we are using the two routers are our regional offfice, i want to know that what is the reason of making tunnel between the two location(Router)and how i have to do tunnel between them (Configuration)
GRE tunnels do encapsulate traffic being sent between the 2 routers but they do not provide much security. If you want to secure the traffic you need something like IPSec.
GRE tunnels are very useful if you want to connect routers over public links but use private addresses on each LAN. Also helpful if you want to run a routing protocol between the routers but they are not directly connected.
