Active/Active Pairs
To configure active/active high-availability (HA) redundancy on a pair of Solace PubSub+ appliances, the following tasks must be performed.
- Step 1: Configure First Appliance
- Step 2: Configure Second Appliance
- Step 3: If you want to use the Config-Sync feature to maintain consistent configurations for both mates, you must also enable Guaranteed Messaging and Config-Sync for the primary and backup appliances. Refer to Enabling Guaranteed Messaging for HA Appliances.
The following command sequence examples assume that the Message VPNs blue and red have already been created, and that the client username account named default belongs to Message VPNs blue and red. It doesn't show how to configure these items; for examples on how to configure them, refer to Configuring Message VPNs and Client Username Configuration.
The following table specifies the required configuration parameter matches for one appliance and its mate for active/active redundancy.
