Load Sharing on Internet link

Hi All,

I have 2x50M +1x25M internet link connecting to Different PE routers of same ISP.All 3 links are terminated on same CE Router.

I want to loadshare between all 3 links.Please explain me how to achieve this.Would like to know for both Incoming and outgoing traffic.

Is there anyway to loadshare without using dynamic protocol or BGP?

thanks in advance

Re: Load Sharing on Internet link

Hello Vicky,

for incoming direction even using BGP there is limited capability of influencing return traffic.

if all links are with the same upstream provider using BGP with DMZ bandwidth can be a way to achieve the desired effects

there are some recent threads where the use of BGP DMZ bandwidth is discussed

A key point is that you need to use BGP and on all  links you need to peer with the same AS number

see

>> Is there anyway to loadshare without using dynamic protocol or BGP?

no, this is a rather complex requirement and it is difficult to achieve this even using BGP
Hope to help
