Hello,
I have an simple idea. Can mikrotik implement his own propietary high availablity solution? For example I have two identical routers, one router is “MASTER”. The second router is connected to master router (by ip), when something was changed on master router then secondary router replicates MASTER config realtime but in “hot standby” mode. If MASTER router fails, the second router handle it’s traffic (using replicated config and switching from hot standby to active mode).
Hi consi,
You have very good idea. I think MikroTik can work on it.
Is this not it?

Thank you pcunite.
vrrp does not sync configs 
Well, vrrp is not suitable for all setups (Sometimes mikrotik is a VPN gateway with Secrets configured on it ), config replication in this case will be awesome
Some kind of config sync (between routers, between central repository) is long overdue and would definitely help with mass-administration of hundred of routers.
Not only on this point, but more in the direction to set up router clusters, and they are balancing the entire
load over the devices, this is then a active/active HA set up and not an active/passive set up like the VRRP.
So in my eyes this can´t be easily done by MikroTik as many of us will imagine, because the only thing
to realise it is to use the CARP or better ARP balance over CARP, it is the same game as the VRRP but over a
virtual MAC address and then the entire load (WAN) can be balanced over many devices (RouterBoards)
perhaps a way not to send the RB1200 & RB1100AHx2 not in pension or set them EoL and let us building
Router clusters with this hardware.
For smaller Routers I personally thing the RAM size is not enough or
to small.
But, the only OS I know is OpenBSD where those set up is really running fine and stable, I have
never heard from Linux based routers that anyone has got this function stable running!
Normally Routers with this feature or function are starting at 5000 € - 7500 €, it could be a market niche
or a real killer function to have for sure!
Not really
Juniper SRX100:
Not really
Ok its perhaps also able in less price ranges, but often also likes VRRP a “active/passive” solution
and/or a proprietary high availability solution by each of the vendors, but fore really “active/active”
solution with out paying license fee to the big ones it is in my eyes the best solution to work with
arp balance over CARP. would being nice if they implement it at some days or plain inserting it in RouterOS.
So even also 5 or more Routers can be natively stacked to a router cluster and if more are needed for bigger
BGP set ups perhaps syncing over a fast Switch.
The VRRP solution I love also but not for every set up and its in my eyes not really the same as a real
router cluster that is active balancing the load over many devices.
There is no problem to decide wich protocol to use…
There is problem to keep same config on two routers
(Configuration replication from master to slave + hot-standby of slave host)
