MPLS Load Balancing between 2 links

[tyagi.v]

Hi ,

I have 2 scenarios as enclosed in the ppt , I want to achieve load-balancing among among 2 MPLS links , can you please suggest how I can achieve this ?

Thanks

Hello,

what sort of routing are you using (static/BGP) ?

HSRP does not allow load balancing, you would need GLBP.

Hi Georg ,

We are using BGP with ISP's over MPLS links

MHSRP on WAN routers to load-balance LAN traffic 

Now  want to do load-balancing between 2 different MPLS links ( both links are from different providers)

Thanks

Hello,

you have numerous options. Have a look at topology 4 and 6 in the attached selection of sample configs,,.

Hi,

Share your BGP configuration so we can guide you more. As I am getting your question that both your destination is reachable from both MPLS than you had configured BGP correctly. 

By default, BGP chooses one best path among the possible equal-cost paths that are learned from one AS. However, you can change the maximum number of parallel equal-cost paths that are allowed. In order to make this change, include the maximum-paths paths command under the BGP configuration.

So in your case, your configuration will be like:

router bgp <AS Number>
maximum-paths 2

I didn't you about the use of MHSRP.  Please explain a bit more so we can understand that will it required or not?

Thanks Deepak & Georg ,

In our case we have 2 MPLS links from different service providers , we don't have Public BGP AS number , rather using private AS numbers , so here my query is that can I do load balancing between 2 different providers or my MPLS links will work in active & standby only ?

I don't have much expertise on MPLS & BGP so this question could sound little generic also :)

Thanks

Hi,

Yes, you can do it load sharing on both links with help of BGP. There is no issue. As I said that share your BGP configuration and MHSRP as well to understand the network topology.
