Which address to configure for configsync?

Jie - my thoughts / 2c on this are as follows.

Pros of HA VLAN - no further overhead on the TMM interfaces, which you want to leave alone, where possible, for application traffic. If utilisation is high on these TMM interfaces then this does not affect the failover traffic and cause problems here either.

F5 recommend, I believe, that the HA VLANs are directly connected - if you follow this practice then this further isolates outside network infrastructure issues from these key failover services.

Hope this is useful,
