Hi all,

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..

next POA..

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..



I have this problem too.
