GRETAP
^^^^^^
While normal GRE is for layer 3, GRETAP is for layer 2. GRETAP can encapsulate
Ethernet frames, thus it can be bridged with other interfaces to create
datalink layer segments that span multiple remote sites.
Layer 2 GRE example:
.. code-block:: none
set interfaces bridge br0 member interface eth0
set interfaces bridge br0 member interface tun0
set interfaces tunnel tun0 encapsulation gretap
set interfaces tunnel tun0 local-ip 198.51.100.2
set interfaces tunnel tun0 remote-ip 203.0.113.10
Troubleshooting
