Tunnel keys
^^^^^^^^^^^
GRE is also the only classic protocol that allows creating multiple tunnels with the same source and destination due to its support for tunnel keys. Despite its name, this feature has nothing to do with security: it's simply an identifier that allows routers to tell one tunnel from another.
An example:
.. code-block:: none
set interfaces tunnel tun0 local-ip 192.0.2.10
set interfaces tunnel tun0 remote-ip 192.0.2.20
set interfaces tunnel tun0 address 10.40.50.60/24
set interfaces tunnel tun0 parameters ip key 10
.. code-block:: none
set interfaces tunnel tun0 local-ip 192.0.2.10
set interfaces tunnel tun0 remote-ip 192.0.2.20
set interfaces tunnel tun0 address 172.16.17.18/24
set interfaces tunnel tun0 parameters ip key 20
