Some Experiences with VRRP

RouterOS General
1

Hey MT Users,

had someone a VRRP Setup in use? Is it working or are there some Bugs and its not stable?
What kind of Hardware you used?

Thanks

I have it deployed in two locations right now.

We use it internally in two instances, one for each of our routers at each end of our network. If router A fails, traffic destined to that gateway goes to router B. If router B fails, traffic to router A, etc. It works as expected and I have not encountered any bugs or stability issues.

I’m running 6.7 currently. Our in-house setup is on x86 and the setup I have deployed for a client is on the RB2011 platform.

Thanks for your Report! Im planning to use 2x CCR 1036 SFP+ and dont waste my Money :slight_smile: Sounds great!

If im using 2x CCR for it:

Uplink_01 @ 10 GBit SFP+ ----   CCR_01       >         |
                                  | 10 GBit Link       |   ---- Core Switch (HA Setup)
Uplink_02 @ 10 GBit SFP+ ----   CCR_02    >            |

What happens if 15 GBit Bandwith are incoming? They loadbalance between the Units? How they balance?

VRRP is not a load balancing method.


Virtual Router Redundancy protocol, or something like this.

Or it’s working Router A or is working router B. When Master dies, the child start to work as master.

Like Ibersystems said, VRRP is for failover.

If you want to load balance, you’d have to have a separate system in place. My configuration is setup similar to this wiki entry:

I control which default gateway is assigned to my computers via my Microsoft Active Directory setup. A startup script is run on machines in certain OUs to set a DHCP user class ID. From there, my DHCP server looks for this class ID and if found assigns my “alternate” default gateway so they use a closer router.

Thanks for sharing, if im built it and tested it, im come back with my Review, but it would take some weeks / months.
