Hi all
I am attaching a reference diagram for the kind of architecture I am struggling to achive. Any suggestion to implement the same will be welcome.
As per required design I can identify few problems
1. Ideally, controller should be connected to two switches. These two switches being Cisco, should be running HSRP and have HSRP VIP as their deault gateway. Other option is to have Cisco switch configured as VSS ad create LAG towards the same. This is desired for redundancy to Master/Backup controller at the network edge.
2. LMS at the remote sites will need to contact the active Master. Master/Backup again is desired from the redundancy point of view. As these controllers are far apart from each other I might not be able to extend a VLAN specifically for VRRP between two sites. Reason I am looking at option where L3 can be configured to provide VRRP kind functionallity.
3. As per solution, both the master and backup should be accessible to the rest of the domain.
Looking for suggestions from experts to implement this scenario.
Thanks
