+Arista EOS
+^^^^^^^^^^
+
+When utilizing VyOS in an environment with Arista gear you can use this blue
+print as an initial setup to get an LACP bond / port-channel operational between
+those two devices.
+
+Lets assume the following topology:

+.. note:: When using EVE-NG to lab this environment ensure you are using e1000
+   as the desired driver for your VyOS network interfaces. When using the regular
+   virtio network driver no LACP PDUs will be sent by VyOS thus the port-channel
+   will never become active!
