AltostratusLTM HA between separate site
CirrostratusHi,
Are all VLAN's available in both DC's via the MPLS network?
I would create a Device Group with both LTM devices for Sync-Failover. Use a seperate VLAN for Config Sync and use failover method 'Network' because the serial option cannot be used if the LTM devices are located in different DC's.
Maybe you can use two Traffic-Groups so users near DC1 are using the VS's active on the LTM in DC1 and users near DC2 are using the VS's active on the LTM in DC2.
But in this simple setup the VLAN's for the VS's and the Pool Members must available in both DC's.

CirrostratusYes, when creating Traffic-Groups, you can have one Traffic-Group active in DC1 and standby in DC2. The other Traffic-Groep is active in DC2 and standby in DC1. But you just want simple HA.
For HA to work, both BIP-IP appliances need the same configuration in terms of nodes, pool-members, pools and virtual servers. This is the kind of information that is synced in a Sync-Failover setup. Also float-IP's are synced. I am not sure what happens when float-IP is synced to a LTM device on which the VLAN and subnet is not available.
Does not sound like a stable setup.
