I have one router with 3 interface two for ISP the for the Lan I want to get maximum data rate between 2 Interface (i want to add my 2 ISP).please tel me how are do

You need a device at the other end to accept the specified bonding protocol, otherwise it won't work. Are both the ISP connections from the same provider? If they aren't then you most definitely won't be able to bond the interfaces.

If you are looking to load balance the traffic, then PCC or Nth are what you are looking for.

I want to add two connexion on a same router
thanks

From the same provider or from two different providers?

If it's from the same provider you'll need to call them and see if they support any bonding protocols. If from different providers or if they don't, then you are stuck using some failover/load balancing method.

how can i test if the provider accpet bonding?
by try or call
i like to know if iam as provider prevent my client from bonding connection

You'll have to call the provider and see if they would support any kind of bonding. You'll also want to try and get sent up the support chain as I'm sure their Tier 1 techs won't have any idea what you are talking about when asking about bonding. They may also charge you if they do support it and set it up since it will require work on their end to get everything up and running since I'm sure it's not something they normally do.

If they don't support bonding, the only thing you can do it set up load balancing to use both lines.

i like to know as iam provider how prevent my client from bonding my connection

Don't set it up for them when they request it?

i think by defult mikrotik will allow bonding

Bonding only works if you set up the MikroTik for it. By default it won't work/accept it, because it won't be listening for the protocols for it to negotiate bonding.

what if i want set it up for them whati should do to allow bonding :d
thx

You don't 'allow' bonding and then they can suddenly use bonding, you configure it for them. Bonding needs to be configured on both devices.

Here's the manual: http://wiki.mikrotik.com/wiki/Manual:Interface/Bonding
