MikroTik FINALLY Supports BFD in v7!!! (BGP & OSPF Setup)
ฝัง
- เผยแพร่เมื่อ 11 ก.ค. 2024
- Many of us have been waiting for what feels like years (because it has been) for BFD to release on ROSv7, and guess what. It's FINALLY here guys!!! I've been testing this since 7.10 released and I am very happy with how things are working. I have this running on both OSPF and BGP and it does exactly what I need it to. And hopefully it also allows many of you to start deploying v7 to your networks. This is a cause of celebration!
I'll mainly just be walking you guys through the setup process. Use the chapters to skip to the lab or specific protocol setups.

So powerful.. So elegent.. 👍
Thanks sir for this vids...
Thanks sir!!! :)))
I'm looking into getting Mikrotik with Ubiquiti Wifi APs (to replace my old homegrade Asus AC66U-s) and find your videos really good, educational and well packed with info! Stumpled upon many of them :)
Finally, BFD! I was trying to test it at the end of last year with OSPF, (RoS 6.49.7) only to find out that it was broken.
SEPULTURA \m/ :)
28:45 maybe you would need to set the VRFs exclusively for VRF interfaces other than MAIN - could be a thing
btw. with [F6] you can hop through windows in a winbox session ;)
Hi there, I want to use OSPF + BDF for lets say two WAN links ( LTE and starlink) and connect them to a CHR router over wireguard.
Over the wireguard will run L2TP transparently (not encrypted) mainly to have MRRU tools to massage MTU as necessary.
The part I am having trouble with is setting up the OPSPF and BDF.
thanks sir
would you please add video and show how to setup v2ray client on mikrotik docker. I really need it and help me bypass restrict
9:24 Hmmm... I did some tests a few weeks ago and there when I set a link down directly on the router OSPF is very fast to notice about it. Makes it a difference if the link goes down on the router itself or it goes down otherwise?
is there any use-case for using different tx/rx timers?
1:29 haha spotted
I new you like BFD support in ver 7.10. but how you fix wifi issue in hAP ax3 with version above 7.8?
I can not use BFD with lossing wifi every couple of hours due to bug is wifiwave2.
MT is still working on the bug effecting Wifiwave2,, there is an alpha package they have given to users to test with on their discord but haven't seen any other news.
A bit off topic but does anyone know how to see the AS path of a received BGP route in version 7? Its a mystery to me! Or is it just not available to see yet? ta
Should be able to see the AS path via Winbox and double clicking on the BGP route you want more information on, then just navigate to the BGP tab and the AS Path is there.
@@TheNetworkBerg Hi do you know if it is possible to do this from command line? Because "ip r pr detail where dst-address=xxx" doesn't give bgp AS path and loading 2 million routes in winbox and applying filters to find the prefix makes winbox a bit wobbly. Thanks
3:59 Wait! In OSPF when a link goes down it is very fast to route it over another way... For me the BFD there make sense only to message faster when a router is going down, not the interface is going down. And in BGP of course
The question is do you consider a few seconds to be very fast or a few miliseconds? BFD lets the forwarding engine know almost instantaneously if an interface where BFD is configured on is no longer receiving any messages and to consider it as down creating a much faster re-convergence of the network.
@@TheNetworkBerg in my tests when I click disable in the routerOS for the Interface it was very fast, unser or equal 1sec or so I think...
But this is of course not the way a link goes down usually😅
@@m-electronics5977 but that's just it, in the real world you might have a cable coming into your MikroTik on an interface and between your MikroTik and whatever device it is connected to there is connectivity so interface doesn't go down and further down the line maybe 100 KMs away there is a problem and BFD can allow you to detect faults like that so that it will tell the router the interface isn't good to use.
@@TheNetworkBerg ya, that is what I also unterstand, I would only say this that when a link manually or otherwise set down on the router ospf reacts very fast
Will it work between routers running ROS 7 and ROS 6.x ?
I think the real question is, 'Would you be able to get it working with RoSv6?' I tried in December, but with no success, and there were a lot of complaints in the MikroTik forum about it.
@@sergiobeltraothe feature was released in v7 2 weeks ago.
@@BattousaiHBr It was available on v6 but wasn't working anymore
@@sergiobeltrao yes, it was available in v6, but not v7. they re-implemented it in v7 only a coupole of weeks ago.
Do u know how to enable openvpn for ipv6 in mikrotik
Not something I have done before so off hand no, but it should still be a similar process just using IPv6 to connect with?
Can I use it on VRF ?
Yes I used it with a vrf later in the video
@@TheNetworkBerg thanks let me check.
Need help
