I am trying to get load balancing over 2 wan(isp link) and router redundency as well.. but failed to get the solution..
Now need expert suggestion to achive it..
I have attached the diagram for reference...
Routers(3845) connected to 2 ISP, traffic need to be shared on both.
ASA 5520 configured in routed mode, active - failover and doesnot support PBR to load balance at ASA level.
Static route is being used..
I tried below things and failed..
1. GLBP on router to do load balacing and router redundancy:
Prob: GLBP work best with multiple clients.. in diagram there is only one client i.e ASA..
2. I tried giving 2 default route at ASA but not working when one fails or any WAN links fails..
Now i am goin to use OSPF on routers, ASA and L3 switches in LAN.. not sure if this will work fine..
Need expert suggestion on it..
