Re: load balancing

Depends on what routing protocol you are running on your side, and what hardware you are using. Can you post this info ?

We are the ISP we are using BGP at our end .

Customer has 1700 cisco router & L3 switches .

Can you send us the configuration to load balance .

Re: load balancing


Most ISPs won't let you run anything else besides BGP with them. The main implication here is that you can really only use default static routes to load share.

ip route serial0/0

ip route serial0/1

...and source a default route into the rest of your network from here. The mechanism for that depends on the IGP that you're using.



Re: load balancing

It seems you would give the customer a block of IPs as would the other ISP. His best bet to load balance is to use the two blocks of IPs in conjunction with Policy Based Routing. Basically, he could assign (or through NAT) half of his hosts with your IPs and the other half with the other ISPs' block on his router, then policy route from his router based on what the source IP is to the appropriate ISP.
