I'm required to implement a multisubnet availability group using SQL 2012 under the following requirements:
1. Legacy drivers that do not accept MultiSubnetFailover=TRUE
2. No DNS update from SQL Servers. DNS responds with multiple statically entered IPs for the listener.
3. No streched VLAN. Geographically separated SQL on separate VLANs.
Could this be done in a way that legacy applications failover correctly?
