Scenerio for Load balancing and Redundancy

Unanswered Question
Jan 24th, 2010

Dear All,

          I need a scenerio to implement in my office network.  I have two different ISP with 2 Routers.  Each Router have 3 Interfaces (1 WAN & 2 LAN Interface),  I have two Core Switches with CASCADING CABLE in Redundancy (One is master and other is member).  Please any body can give me any link or scenerio to put full redundancy and load balancing at Router Side and Core Switches Side.

          Please i am waiting for support.

regards,

I have this problem too.

Hello,

It seems that you already have switch redundancy by stacking them.  So, in this case if one switch fails the other will take over. Just make sure your edge switches connect to both core switches. Also you should run VRRP or HSRP facing the users subnets on your core devices, so if one switch fails you users don't loose connectivity.  For you routers facing the ISP, you should have a connection between the 2 routers and run dynamic routing protocols (preferably BGP) to give you redundancy.
