Hardware fault tollerance

RouterOS General
1

Hi,

I have a routerOS with 7 lan interface (with hotspot, bandwidth queues,…) and 1 wan interface.
Here the overview:

Now I want to give more stability with an hardware failover. What I want is a system similar to cisco pix where two routers are seen as a single router. In this way, I run a single router, the other is like a mirror. When the router1 fails, the router2 becomes active, without interruption of services (or with a short break).

Any ideas?

Thanks in advance

VRRP provides you with such feature

Ok.

Well, I think that is the solution for me. Some doubts:

  1. I have two routers R1, R2.
  2. R1 is completly configured (firewall rules, nat, hotspot,…)
  3. R2 without any configuration
  4. For each interfaces (X is the lan id - see network diagram before):

R1 configuration:

/ip address add address=192.168.x.254/24 interface=etherX
/interface vrrp add interface=etherX vrid=49 priority=254
/ip address add address=192.168.x.254/32 interface=vrrpX

R2 configuration:

/ip address add address=192.168.x.2/24 interface=etherX
/interface vrrp add interface=etherX vrid=49
/ip address add address=192.168.x.254/32 interface=vrrpX

Is this correct? Or I need to duplicate on R2 every configuration (firewall rules, nat, hotspot,…)?

Thanks in advance.

VRRP configuration is correct.
If you want to run hotspot or some other facilities, then of course their configuration must be the same on both routers.

I do a more specific post in scripting section about master/backup configuration sync.
