Virtual Link Trunking (VLT) is a Layer 2 multipathing technology that creates a link aggregation group (LAG) for a server, switch, or any device that supports LACP to two different upstream devices. The active-active connection improves and provides high availability to the southbound server/switch. The current data center designs use VLT technology to provide high availability of access layer switching to the southbound servers/switches.
In this playbook example, we use the following roles to configure VLT:
os10_interface
os10_vlan
-
os10_lag
-
os10_vlt
