  • Load Balancing on routers

    Dear All,

    I want to implement load balancing on two routers. I have two separate ISPs one with 170Mbps and other with 60Mbps. If there is no space in first ISP and there is space in second ISP traffic should go through that and vice versa. I have already implemented load sharing through AS prepend. Can anyone help me in this regard. Topology diagram is also attached.

    I'm not a network expert, but will give you my 2cents worth.

    To do the load balancing you need to define where it happens on the LAN outbound to the internet or on the WAN inbound.
    Then what services/ protocols are you balancing, http,https, FTP etc.
    Then you drop a suitable appliance, probably application aware to do the work.

    Simple or even complex LAN outbound can be done with a high end Sonicwall, Cisco, Watchguard firewall.

    WAN inbound will need something like a Netscaler or a Kemp appliance hosted outside doing the load balancing while being aware of traffic to the site and the state of servers and work load.
    The most important thing in life is to be yourself.

      Thanks for the reply. But we are not performing any NAT and nor we want to perform any NAT.

        he never mentioned NAT.

          Re: Load Balancing on routers

          Dear All,

          We want to implement load balancing on two routers using public AS number. We have two separate ISPs one with 170Mbps and other with 60Mbps and we have established eBGP connection with the two ISPs.

          Currently, we are performing Load Sharing, we have advertised Pool A on ISP - 1 and also advertised Pool A on ISP - 2 with AS Prepend and similary we did the same Pool B advertised on ISP - 2 and also advertised Pool B on ISP - 1 with AS Prepend. With the help of AS Prepend we are achiving Load Sharing and failover support but we are unable to achieve true Load Balancing. Like if ISP - 1 is completely consumed than load should be shifted on ISP - 2, if there is room in ISP - 2. Likewise, if ISP - 2 is completely consumed than, if there is room in ISP - 1 then load should be shifted on ISP - 1.

          We do not want to perform any NAT. So is there any way we can achive true Load Balancing? Please share your ideas.

            Please don't bump threads.

            Sometimes, it may take a while to respond. Sometimes, unfortunately, there aren't members with sufficient experience to provide the sorts of answers you want or need.

            In those instances, it's best to partner or work with a consulting or contracting firm who have te sort of expertise you require.

            Considering the sort of technical level you're talking about requiring, you should almost certainly find a contracting firm who can assist.

              Contact your ISP's and possibly a multi network provider. Find one you trust!
              Get them (ISP or MNO) to take control of the connections and deliver their preferred method of load balancing.

              What you now require is possible for a well sourced network provider.
              Making sure it works...when it's supposed to, will take some planning and testing and may require balancing the connections.

              As mentioned a well experience contractor may have a better solution, but you'll still end up talking with an ISP/MNO, so let their engineers design and deliver the solution.
