Dear sir,

iam having 2800 router and i have 2 isps
i have one is airtel and vsnal now i want to terminate these two links on 2800 router and i want to implement isp failover on ethernet and these two links on loadbalance.

plz give me config examples.

Regards
srini



 
This isn't something that configuration examples is really going to help with. Load sharing between two ISPs is a complicated topic that requires a technical knowledge of BGP as well as an understanding of how routing on the Internet works from a policy perspective.

Once you understand the technical and policy-related hurdles, you need to get your own address block, at least a /24 or bigger or it won't be routed properly. Then you'll need to get your own Autonomous System number from whichever organization serves your region (ARIN, APNIC, RIPE, AFRINIC, or LAPNIC).

Once you've done all of this and you have it configured properly, you still will not ever get perfect load balancing. You have complete control over how traffic exits your network, but you only have a small amount of control over how traffic comes to you.

There are better ways to do this. Do you really, honestly need two different ISPs? If not, do load balancing with one ISP. That is much easier and does not require BGP.
 
Dear Jneiberger,

Thanks for valuble reply i understood what ur trying to say me .

Now i have 2 leasedlines 2x2 mbps (4mb)(v.35)now iam planing to connet these 2 leased lines on junipher firewall
i want to achive ethernet failover and loadbalance on that firewall.

if it is not possible i have 2800 router how can i do this on the router.plz give me some examples.

Regards

The firewall is not designed to do that, either. It is not a router. You might be able to setup two default routes, one pointing to each ISP, but that will only give you failover, not load sharing.
