You can connect System A and System B and congure them as VLT peers as follows:
1 Ensure that PE IDs of PE 1 and PE 2 are dierent. The IDs should be unique and cannot overlap during the conguration.
2 Ensure that System A and System B are upgraded to OS 9.10(0.) or later.
3 Enter VLT-domain conguration mode for a specied VLT domain. Ensure that both the systems are congured with the same VLT
domain ID.
CONFIGURATION mode
vlt domain domain-id
The range of domain IDs is from 1 to 1000.
4 Congure the default MAC address for the domain by entering a new MAC address.
VLT DOMAIN CONFIGURATION mode
system-mac mac-address mac-address
The mac-address format is nn:nn:nn:nn:nn:nn.
5 Congure the unique unit ID (0 or 1) to each peer switch.
VLT DOMAIN CONFIGURATION mode
unit-id {0 | 1}
Congure a dierent unit ID (0 or 1) on each peer switch.
NOTE
: The system MAC and unit ID are the mandatory congurations to be done so that the dual homing functions
properly.
NOTE: After saving the congurations to the startup-cong, reload the system with unit ID 1. This is mandatory and
proceed with further congurations after reloading the system.
6 Add VLTi for the election to happen between the systems.
7 System A and system B become VLT peers after the election of primary and secondary VLT units.
8 The PE connected to primary is online and PE to secondary remains oine.
9 Import the congurations of peer systems in both primary and secondary CBs by using the import peer-config command. This
ensures that the provisioning and interface congurations of the PE connected to the peer chassis are imported into the running
congurations of the respective CBs.
EXEC Privilege mode
Dell#import peer-config
10 The secondary PE comes online once the peer congurations are imported.
Once congured, the system starts functioning as a dual homing setup as shown in the following diagram:
