Magic! Thanks a lot brother, I this helped me a lot. Great demonstration!

Beautifully explained, loved it.

The best video on the internet for recursive routing details ;)

Fantastic explanation, thanks man.

Great video and explanation!

In a failover scenario (vice load balancing) its more common to just do recursive on the first route. If the first one is not available then the second route will be used regardless. In this case often folks make two recursive routes for the primary in the case where we go one step further, what if one of the DNS services is down.

You are the best! Thank you!

Very informative. Thank you!

Thank you very much for all the good and nice video's. It is an excellent refresh of the MT courses (MTCRE,MCTINE). Not sure of it is in scope but could you do one with PIM SM together with ospf/bgp routing ? Very populair item with all IPTV setups knowadays. Thx !!!

Very nice video, TNX.

Thanks, it helped me a lot

This channel rocks!

Interesting. Thanks for this.

another great video, thank you.

MikroTik MTCRE - Recursive Routing (Easy Automatic failover even for directly connected networks!) interesting discussion that is kept true, have a nice day

Thanks for share!

Freakin awesome! thanks alot sir!

I've been watching so much about your mikrotik lessons and i learned alot from it i wanna say thank you for the effort that you put in teaching these videos but can i ask if you could make a video about gaming prioritization?

Hi, can you adapt this tutorial using ROS 7 and also using lte as one of the connection ? By the way thank you for your remarkable work !

YES!!!!! Thank you

Hey Berg, nice video and explanation. Do you mind using RouterOS v7.x, in this newer versions, you need to change target scope also, in order for this to continue working. Otherwise, a horrible headache will appear.

thank you. so. much!

Thanks A LOT LOT LOT

thank you

Wahoo - this is exactly something I want to do. I'm on RoS 7.X (because the new device shipped with that).

But how to apply this if the ISP1 is just giving intermittent connection? The link is up, Internet is online, it just that intermittent with ping reply and timed out, not a total link failure. Can this also do the trick ? I understand that this setup is only for ISP1 with link / interface down or offline.

great information and technique, well is there a way we can make logs when WAN1 goes down and goes Up ? so to check later on and to diagnose??

Thanks, network berg for your immense contribution to networking. I have this error from my Mikrotik router port interface below. I have bought the original cable and changed from auto-negotiation to 100mbps speed. This effort did not resolve the issue, kindly advise. Thanks ether2- SECTOR2 RADIO fcs error on link

Hi sir, Thanks for letting us know about this, its so help me a lot, hope you don't mind, i am applying this for Mikrotik CCR2116 but it coudn't run, hopeyou can help me. Thanks a lot

This is very informative. I use this mechanism for a while now. In combination with netwatch it is even more powerfull. But.. with Ros 7.x it doesn't seem to work this way. Maybe you can make a video of this based on ros 7.x. thanx. I like your video's a lot.

Thank you for the video, explanation is great. Is there a way to send a notification via email when one route is down? this is because it could be a remote site and this way you know one internet service is down. thanks again for the video.

Hai, I am new to Mikrotik, my isp providing bandwidth by using RouterBOARD 3011UiAS as main server using port 4 and for failover connected ccr1009 to port 5(RouterBOARD 3011UiAS) when main server input goes down i have to manually change route to ccr1009, is their any way for auto failover, and i am using hotspot logins for 70 customers. I hope you understand my question. both lines from same isp

Thank you so on this way no need i think to add dns because it already added on router for each ISP is it ok ? or i should add dns on ip/dns add dns

Sir i want some infromation please make video in multiple recursive if WAN1 fail to shift WAN2 automatically if there is no internet also in WAN2 then all traffic should be move to WAN3 please make video on this setting thank you

plz what topology are u using for the lab

make a video of this based on ros 7.x. thanks

Excellent video but I am having problems trying to replicate this configuration when the default route is given to me via DHCP server. My fear is if I force to put static route ignoring the DHCP Server's input the ISP changes the IP pool and default gateway my remote site will be isolated. I was thinking more to have the DHCP to assign the default gateway and increase the distance and apply this configuration but the routing table displays unknown immediate gateway

How can we do netwatch in this scenario? If primary down send notifications

This is awesome. Thank you. Just a question, how could you implement an email notification to advise ISP1 connection is down?

Once primary link comes up, router is not sending traffic on it. Link gets down, untill we remove cable of second ISP. Please suggest....

Is it possible to implement this with a dual dhcp wan setup that is doing load balancing? It would be nice to be able to monitor up status for both ISP's (and drop one if it is down) while still allowing for the load balancing to occur.

My recursive route does not seem to work , not sure what I am doing wrong lol. Immediate gateway just says unknown instead of recursive.

Hello Sir. I saw this video, excellent, congrats, however like others said in the comments, my ISPs are using DHCP, so my problem is to make the recursive using DHCP instead. So, have you tried implementing recursive routing using DHCP for the wan? And on my scenario, the secondary wan connection is an LTE. Thanks.

Tested and fail over to backup link works perfect only once the primary link came back online, I have to ask clients to restart their routers.any hack for this?

not working with V 7.2.3 (mmips) - its that possible to recursive routing on V 7.2.3 (mmips) ?

is posible use recursive routes with vrf?

It seems that the route to the IP check has to be done through an IP address, it cant be an PPPOE interface. Is it possible to use a PPPOE interface?

everything is ok when you use ip addresses for gateways. but i had rule set not by ip addrress but by interface. and recursive routing is not working that way. why??? normal routing works ok when you use interfaces even simple fail over works but not recursive.

no need mangle sir?

Sir please Make a Video On Mikrotik Hotspot Social Login Facebook

Hi Network Berg, im not sure why , but in v7 scope/target scope are calculated differently. If you do same thing in v7, that will not work

I have been using the recursive routes for most of the mikrotik routers i have used in the last years but the recursive routing will not work on RB4011. Any suggestions?

That only works for v6, for v7+ target scope must be bigger than scope. Here is a Recusrive Routing + Failover very weel explained as well: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eTmpBAAW_pQ.html Nice work anyways, I love your channel! Awesome backgrounds :)

Mikrotik Policy Routing Based on Client IP Address on ROSv7. please

Does this work on v7.11? I just tried this and doesn't seem to work.

I am getting so frustrated with this! I have tried to do this many times now, but it doesn't work. Both of my ISPs use DHCP. I try to use ports where you us IPs (other than the 8.8.8.8 and 1.1.1.1) - but my primary connection always fails. Secondary seems to work. I never get the status showing 'recursive by x' under the Gateway column under the Route List. The reference you gave for the link to Mikrotik's steps to setup recursive routing doesn't work - maybe an earlier ROS? I have ROS 6.48.6. Mine will not let me use cli to configure /routing/table (the second set of steps). Plus, the steps/method are very different than how you do it. Your way seems simpler and more modern approach. Does this not work with some ISP's? I am using Starlink in bypass mode as my primary and a cellular AT&T connection as my secondary. I cannot find anyone with any instructions how to setup this recursive routing where their ISPs are giving their internal router IPs via DHCP - which is the most common way it is done... Pulling my hair out :(

How bout if I have 3 ISPs or more sir?

port forward not working the mathrd

What's next ?

Or do I understand this step, because I have more than 8 service providers

its easy to work with a script

if your video translation to arabic. it would be beautiful

HELP ME CONFIGURATION TEAMVIEW REMOTE ?
