Network Security Tunnel

Question

In the Tunnel Interface, when I edit the tunnel information, it shows:

Attributes          Values
 Tunnel Source      IF10    
 Tunnel Destination 1.0.0.1
 Tunnel Mode         GRE

What does IF10 stand for in the field for Tunnel Source? Why can IF10 be the source for more than one tunnel?

Did any answer help you? If so, you should accept the answer so that the question doesn't keep popping up forever, looking for an answer. Alternatively, you can provide and accept your own answer. — Ron Maupin, Dec 25, 2018 at 10:05

You didn't explain what router model this is, but it is almost certain that IF10 means Interface 10.

An interface can be the source for multiple tunnels because a tunnel is defined by two endpoints, and one interface is only one end.

FYI, GRE is not secure. You would need to use a tunnel that does encryption for a secure tunnel.
