Load-balancing and Fail-over in MikroTik Tutorial
November 6, 2009 | Posted by admin ISP where we work as an administrator to use more than one gateway to connect to the Internet. Everything must be able to serve the upstream & downstream service. Because the case would be different if one of them can only serve downstream, for example when using VSAT DVB One-way.
For this case such ISPs have 2 lines to the Internet. One use access DSL (256 Kbps) and others use Wireless (512 Kbps). With DSL usage ratio: Wireless = 1:2.
What to do :
1. Using all the available gateway channels with mikrotik load-balancing techniques.
2. Making one as a back-up with mikrotik fail-over technique.
OK, let’s just get started experiments at mikrotik:
1. IP address for access to the LAN:
> /ip address add address=192.168.0.1/28 interface=LAN
IP address for access to DSL lines:
> /ip address add address=10.32.57.253/29 interface=DSL
IP address for access to lines Wireless:
> /ip address add address=10.9.8.2/29 interface=WIRELESS
Specify the gateway and the ratio of each:
> /ip route add gateway=10.32.57.254,10.9.8.1,10.9.8.1
2. In the case for mikrotik fail-over technique. Assumed to be the main route through Wireless with DSL lines as a back-up if the main line were impassable. To check whether the main line can be passed or not, use the ping command.
> /ip firewall mangle add chain=prerouting src-address=192.168.0.0/28 action=mark-routing new-routing-mark=SUBNET1-RM
> /ip route add gateway=10.9.8.1 routing-mark=SUBNET1-RM check-gateway=ping
> /ip route add gateway=10.32.57.254
