.. cfgcmd:: set interfaces {{ var0 }} <interface> evpn uplink
**Configure this interface as an EVPN-MH uplink interface.**
If all uplink interfaces on a PE device go down, this PE device loses access
to the VXLAN overlay. To prevent traffic blackholing, the PE device forces a
protocol shutdown (protodown) of its downstream EVPN-MH interfaces.
The following example configures {{ var1 }} as an EVPN-MH uplink interface:
.. code-block:: none
set interfaces {{ var0 }} {{ var1 }} evpn uplink
