Tunneling provides a way to encapsulate arbitrary packets inside a transport protocol. This feature is implemented as a virtual interface to provide a simple interface for configuration.

The tunnel interface is not tied to specific "passenger" or "transport" protocols, but , it is an architecture that is designed to provide the services necessary to implement any standard point-to-point encapsulation scheme. Because tunnels are point-to-point links, you must configure a separate tunnel for each link.

Maximum bandwidth for the interface that is denpends you can spacify under tunnel int ..

as permy kowledge 40Mbps...bcz i specified the same. :).

I am trying to give your answers ( Experts, correct me if I am wrong)

if on your router total two interface exists, i.e. serial0/1/0 and fastether 0/1 in which fast ether 0/1 is connected to your LAN and serial is connected with WAN links, and you want to connect to other 20 sites at outer side and want to manage traffic then you can create tunnel for each site and give tunnel source IP as your WAN interface IP and tunnel destination IP as other site WAN IP. in this way you can move traffic from your one site to other 20 sites using only one WAN interface. no need for 20 routers. tunnel will use the bandwidth of WAN interface, lets say WAN is having 2 MB speed then its divided by all tunnel interfaces.

hope this helps

Thanks,

Jigar
