MIkrotik - REAL HA Configuration

[@Chadmarshall357]

Been looking for something like this for a while, great video! Just to add another piece to this, with Netwatch and Scheduler (for permissions) you can have the HA kick in for a physical port failure on your device. For example, if your uplink port dies/faulty SFP/faulty cable, you can have it kick over to the standby board by running the ha-switchrole script after x seconds of not being able to reach your defined IP address. Keep up the awesome work!

[@danielr6692]

Awesome to know about HA! Thanks for all your dedication and work! Very apreciated.

[@RickardUddenberg]

Great. And good whit the backgroud music, makes it easy to take in what you are saying. Instead of just a hard voice.

[@MaxPilloni]

I really hope there will be soon any clustering/stacking (or virtual stacking) option to show two mikrotiks as one device with two modules (like a typical hp or cisco or whatever switch would do)

[@TheNetworkBerg]

I really wish that too Massimo, honestly! This is a feature that has almost become baseline in most equipment. There is still no indication of when true HA will be added to MikroTik as it's not on their roadmap and even in the current RoSv7 builds there is nothing hinting towards it coming. Some other neat carrier features though! But make sure you are seen, post about it on the MikroTik forums whenever they ask what things you would like to see in the new RoS version. And hopefully it will become a reality someday.

@@TheNetworkBerg in those days I’ve tried to use MLAG from last release of RoS 7beta. I have a guide released by Mikrotik itself but it doesn’t seem to work. I’ve opened a support ticket but from the answers I receive I think I’ll have no luck in making it work…

[@sami_darkeyes]

Can you make a Load Balancing/Fail-Over video for multiple ISP including USB LTE failover. There are many videos about Load Balancing and Fail-Over on Mikrotik, but their explanation isn't thorough.

[@gulzaibkhan6913]

Hello bro, while this is really interesting and similar to what i want in my scenario, what MikroTik models are you using ?

[@scbrereton]

Great video. Learnt a lot! Unrelated note, where did you get the Evangelion wallpaper? Looks sick :)

[@agungsapto9356]

have you try on rosv7?

[@classicalmusic2425]

Most ISPs do not have two ports. Usually there is a managed switch to ISP and from managed switch then to two Mikrotiks. Can you do one like that?

[@konaylintun09]

Hi Sir, I have given you full credit for the script and video as this is completely. I hope you do not mind, I have a little question about this VRRP HA. This script can be work when the fail Router replace after? I mean normally the Infra will available Active/Standby. if the Active router failed after Standby will change to Active. we must be replace the failed Router 1.(example- power failed). After the Router replace, how can resync from Router 2 to New router? As i testing the script can't sync to new one. (maybe I'm weakness in this network case). pls guide to me and all it. I'm really appropriate to you.

[@kl5189]

How does it works with side to side VPNs? For example: ipsec and GRE.

[@yannickNGABOUK]

Good thank

[@dashginlazimov4923]

Thanks for such a video, keep going on like this bro. If I upgrade the routers to the new version, am I gonna face any problem?

[@TheNetworkBerg]

Hey Dashgin, you may have issues upgrading to a new firmware. I would suggest always checking on github.com/svlsResearch/ha-mikrotik to see what the current latest stable version is. This does not mean that you cannot upgrade the firmware, though I would suggest doing this on a lab environment or on two blank routers that's the same model to see what the outcome is first. If you do want to go ahead with upgrading the firmware the best option is to start with upgrading the firmware on the passive router and then upgrading the firmware on the active router.

[@hoangvt99]

Hello Sir Is it work on Ver 7.x?

[@TheNetworkBerg]

I do not know, I haven't used the script in a long time. Although another viewer recently told me they have it working on v7. Looking at the github it seems like it might be working so test at your own risk github.com/svlsResearch/ha-mikrotik/tree/master/scripts

[@hoangvt99]

Ok Pro. I will check on my Lab. Thank you@@TheNetworkBerg

[@kirksteinklauber260]

Any intend to get this script updated working on v7.xx?

[@TheNetworkBerg]

Not sure if nathan1 has any plans for it, can check on the MT forums. Although I know that a very active contributor on Reddit, Discord and KZbin is busy trying to make this work with v7 @keepingitsimple / djgizmo so hopefully he can create a working prototype soon. I still wish MT would implement HA themselves as well though

[@kirksteinklauber260]

@@TheNetworkBerg agree with you that Mikrotik should implement this feature!!

[@povvitu8114]

Brother ! when we use HA? What is advantage of HA?

[@TheNetworkBerg]

Hey there, you typically want to run HA at a site where you want to keep downtime as low as possible. The biggest advantage of HA is that there is no configuration changes as both devices will run exactly the same configuration. The network will not even know that one device has gone down and will keep sending packets and frames the whole time. VRRP which is also useful for this type of failover tends to have different configurations and needs to be manually updated on both routers where HA will do this automatically for both.

[@nikolashuminosky6987]

in my case this doesn't work on backup router, from the master i can get the script and i'm uploading to the backup router it's rebooting , and sice than nothing happened.any solution pls

[@TheNetworkBerg]

Hello, I would suggest posting whatever errors you are getting on the MikroTik forum post that Nathan1 is a part of forum.mikrotik.com/viewtopic.php?f=1&t=110690 he might be able to shed more light on what your issue is.

[@nikolashuminosky6987]

@@TheNetworkBerg i made it work, but ONE important thing. i was getting script error!!! why? You know when you adding on MASTER : $HAInstall interface="ether8" macA="[MAC_OF_A_ETHER8]" macB="[MAC_OF_B_ETHER_8]" password="[A RANDOM PASSWORD OF YOUR CHOOSING]" then it pops up on the terminal script and then that script gooes to slave .All this process i was doing on MikroTik terminal. Once i started doing on putty everything was fine...interesting, have you tried that?

[@TheNetworkBerg]

@@nikolashuminosky6987 I always use Putty to connect, even in the video so most likely why I did not encounter this issue :)

[@ciaccino73]

I've tried to follow the configurations but after the first reboot of routerB it seems that nothing has happened. RouterA is active but routerB has no config. I'm simulating on eve-ng with RouterOS 6.46

[@TheNetworkBerg]

I had this same issue with some old code, have you used the latest code from nathan1? Else try this: raw.githubusercontent.com/svlsResearch/ha-mikrotik/master/HA_init.rsc If it still doesn't work I recommend posting on the forum so that nathan1 can also check it out, he is very willing to help when it comes to the HA script :)

[@geogmz8277]

I have done something similar with VRRP by exporting .rsc files from one Mikrotik to the other using FTP. If you add ".auto" on the name of the file is automatically imported as soon as is loaded to the Mikrotik. I need to check this project and see how's this done doesn't need VRRP?

[@TheNetworkBerg]

Hey Geo, this does make use of VRRP between the routers to create a heartbeat interface. Essentially there''s a bit of code that just disables all interfaces except the heartbeat interface of the slave to sync configuration. Once VRRP picks up that the "Master" has died it just makes itself master and enables all the interfaces. I think you could speak to nathan1 directly for more information.

did you check it?

The video is really nice, but please, please buy a boom filter or move the mic. These plosives really hurt my ears.

Thanks for the recommendation, I've been looking at getting a filter relatively soon!
