bonding

hai,

i have 3 ppoe coonection with same isp.i created bonding.afer that internet is not working.what is the solutions.

Hi, if you have three different PPPoE Clients at your Mikrotik, I think that you can’t aggregate them as a single link, the idea of a bonding is to add physically similars ports (like two or more ethernet interfaces) to increase bandwidth by doing load-balancing based on layer2 or layer3 information

Does the Provider support MLPPP?

When you bond multiple interfaces there needs to be a bonding interface on the other site, either an own server or on the ISP sites.
If the ISP is not possibly to do bonding your better of using PPC.

Check out the wiki for more information. It may seem a bit difficult at first but once you get the hang of it its works magic.

i need to do only lod balancing.

Mikrotik offers multiple ways to your load balancing goal:

In your case, you need Per-Connection load balancing. One of the most commonly used is PCC:
