Hello
i just bought a mikrotik routerboard 750, but i am not an expert about routers..

ex: 1 ip with 2 mb/s and 1 other with 1mb/s , after configuring in router . the net i will have will be 2+1 (mb/s) so 3mb/s
Can some one please tell me how to configure this router step by step.. (soz my english is not so good.)
Its very important..
thnx in advance.

please any one can help
its very important.

I think this topic will help you (Manual - Mikrotic routerOS 2.9.2 , page-131)

Static Equal Cost Multi-Path routing
Consider the following situation where we have to route packets from the network 192.168.0.0/24
to 2 gateways - 10.1.0.1 and 10.1.1.1:
Note that the ISP1 gives us 2Mbps and ISP2 - 4Mbps so we want a traffic ratio 1:2 (1/3 of the
source/destination IP pairs from 192.168.0.0/24 goes through ISP1, and 2/3 through ISP2).
IP addresses of the router:
[admin@ECMP-Router] ip address> print
Flags: X - disabled, I - invalid, D - dynamic

ADDRESS NETWORK BROADCAST INTERFACE

0 192.168.0.254/24 192.168.0.0 192.168.0.255 Local

2 10.1.1.2/28 10.1.1.0 10.1.1.15 Public2
[admin@ECMP-Router] ip address>
Add the default routes - one for ISP1 and 2 for ISP2 so we can get the ratio 1:3:
[admin@ECMP-Router] ip route> add gateway=10.1.0.1,10.1.1.1,10.1.1.1
[admin@ECMP-Router] ip route> print
Flags: X - disabled, A - active, D - dynamic,
C - connect, S - static, r - rip, b - bgp, o - ospf
