LTM and ASM configuration synchronization without Sync-Failover enabled

Hi Simon,

Thank you for the reply.

External traffic is distributed based on destination networks with an approximate ratio of 50/50 and DCs operate in acitve/active mode (A kind of usual active/active scenario but failover is based on dynamic routing - BGP).

It means that we have the list of vserver subnets - range "A" and "B". Range "A" subnets are active in DC1 and announced by BGP towards upstream peers. At the same time range "A" subnets are also announced with the worse priority via BGP at DC2. Thus in case of a DC1 network issues range A subnets will be still reachable via DC2. Accordingly we have range "B" subnets that are announced via both DCs but at DC2 BGP priority for this range is better than at DC1.

The list of vserver IPs for each DC is identical. Target (aka real servers) are reachable from both DC1 and DC2 F5 appliances (extended or stretched VLAN capability is utilized between DCs). Hence the the list of real VM IPs and hostnames (as long as pools) is also the same for both F5s.

We do not require session mirroring and BGP convergence delay is fine for us in case network failure occurs and all traffic goes either to DC1 or DC2. The main reason I asked my question was that for me it makes sense to perform LTM (node, pool, vserver) and ASM (policy) setup just once at either DC1 or DC2 node and just replicate configuration to the neighbor node without doing the same job twice.

I hope my explanation was straightforward enough :)
