5 Add VLTi for the election to happen between the systems.
6 System A and system B become VLT peers after the election of primary and secondary VLT units.
7 The PE connected to primary is online and PE to secondary remains offline.
8 Import the configurations of peer systems in both primary and secondary CBs by using the import peer-config
command. This ensures that the provisioning and interface configurations of the PE connected to the peer chassis are
imported into the running configurations of the respective CBs.
EXEC Privilege mode
Dell#import peer-config
9 The secondary PE comes online once the peer configurations are imported.
Once configured, the system starts functioning as a dual homing setup as shown in the following diagram:

You can configure PE 1 and PE 2 from both the systems.
