Is it possible Load Balance 2 t-1's & have redundance

[fpower]

Hi,

I have a t-1 comming into a Cisco 2620 router and then to a 515 PIX firewall, then into my network. I use the Pix for VPN access also. I would like to get a second t-1 to accomplish 2 things. I would be getting the second t-1 from the same vendor,(he is offering a great deal to me).

1. I would like to load balance all internet traffic, incoming & outgoing
2. If one of the t-1 fail, I would like the other to still be able to be used for all internet traffic

Does anyone know if this can be done, even if I need to purchase additional hardware? Could anyone direct me to where I could find information on this?

You still have single points of failure. One router, one pix and T1 to the same ISP.

You can look at other options such as BGP, T1 from same ISP but from different CO, and load balance devices like Radware Linkproof, Fatpipe, Amplify and such.

thanks dx1,

can I ask what you would recommend to accomplish this?

If it's the same ISP, you can just to per-packet loadbalancing. Just buy another t1 wic card and slap it into your router. Make sure the two routes are the same cost, and turn on ip cef. Then goto interface fastethernet0/1 and type "ip load-sharing per-packet".

If the ISP has the two routes to you, the other link should work if one link goes down. Obviously you aren't 100% redundant because you lack mulitple firewalls, routers, servers, etc., but you can have some redundancy with minimal cost.
