How would one announce ospf routes over bgp, example, from providers edge to provider. And ospf in routing table, i have selected redistribution=ospf, connected. Only when i add the network address on routing filter it announces? Any idea on how to overcome this.
Can you please explain how to configure iBGP configuration between ROSv7 and ROSv6 We are planning to setup 2 eBGP routers and iBGP between them And downstream is OSFP. AS of now all working with 1 eBGP v7 and OSPF BUT not getting how to set filter rule between V7 and v6 iBGP router
Thanks for your tutorial. how to configure load balancing and failover (we have /23 subnet and I need to configure Subnet-A /24 will go through ISP-1 and another Subnet-B /24 will go through ISP-2) if any ISP is down then the subnet will go through live ISP.
this scripting format is really terrible to work from the CLI... if you have a big chain with a misconfiguration somewhere and you just need to make a small adjustment you need to either type the whole rule again or print current rule, copy/paste then navigate to the part you want. another issue currently is from the GUI if you try to apply an invalid configuration it will rollback the window to the last valid configuration instead of just popping an error and letting you continue where you were, like it already does in places such as the firewall when you try to use in-interface in srcnat chain.
I totally agree with you and really hope MikroTik spends more time with refining the filters, though something tells me this is at the bottom of their priority list :(
@@TheNetworkBerg as far as editing via CLI is, this would be solved with the addition of a text editor mode like vim, which would probably make it easier to work with than the old routing filters since you don't need to pick the item you want to change. the new routing filters also desperately needs tab-completing (rumor is it's in the works).
Is that whole Route-Filter-thing an ISP/BGP thing? Because in my small understanding, I can Filter via Firewall-Filter, why should I filter routes? I add the routes I want, why should I do such a complicated thing?
Yeah filtering happens more in the internetworking space either between ISPs/Cloud providers/CDNs/Internet etc, though it is still useful in our own networks to configure stuff like automatic failover using BGP
I wonder why are you setting BGP weight and distance both? Only 1 is needed and as this is related to BGP so weight should be here to handle outgoing traffic
It is to showcase how multiple attributes can be changed at the same time. Here are some newer videos on BGP if you are interested in how it works. BGP Intro: th-cam.com/video/M5UypwXmIFQ/w-d-xo.html BGP Attributes: th-cam.com/video/cMNx2PSZ_6Q/w-d-xo.html
Hello help me. I am trying to set up filtering with regex for an edge computer, the rule tries to only accept asn1 that is directly connected and only the asns that are directly connected to asn1. That is, it only accepts two autonomous systems. I had this in rosv6 so when I move it to rosv7 it doesn't work. although it is used as a legacy path.
How do you guys feel about the rework of Route Filters on MikroTik RoSv7? Do you like the new "scripting" style configuration or do you prefer having a popup asking you to just fill in specific details? What has your experiences been on RoSv7, I would really love to hear!
Thanks for the video!!! Until I saw your videos I was struggling with getting started with BGP!. Now I have to upgrade my routers to ver 7.x.x , do a PoC and migrate my connections!
Awesome, this is going to be useful since I plan on upgrading a PROD CCR2004 with x2 Full BGP Tables to RouterOS v7 tonight. This CCR2004 is along my ISPs redundant path so there should be no impact to traffic, wish me luck!
@@TheNetworkBerg Extremely late/morning for me right now and the RouterOS v7 upgrade has NOT gone well :( I can't get a simple iBGP peering from the RouterOS v7 Router RouterOS v6 Router to establish. Not sure if it is user error, but everything I have tried hasn't brought the iBGP peering online (it worked fine on RouterOS v6 RouterOS v6). Trying to get to the bottom of it late at night isn't the best so I will have a better look tomorrow.
For anyone else reading this in the future, it turns out it was indeed user error. I had to make sure to set the local.address to the Loopback IP address to get it to work in the end. The RouterOS v6 -> RouterOS v7 BGP config conversion certainly needs a bit of tweaking to get going right :) I'm monitoring my RouterOS v7 Routers and will see how they go over the next few weeks/months.
Unfortunately BGP VPN is still not working in any of the RoSv7 builds :( In this video I'm using 7.2rc3 which is the very latest build and I can't make it work on this version either.
First of all thanks for the helpful tutorial to get some idea about the new changes in RouterOS related to BGP. Can you please share the info about the software/tool you used to create the network topology?
Unfortunately v7 does not have any discard function so all routes will remain in memory therefore they will stay in the routing table, just marked as red. (No way to remove it :()

I miss "ip route print where received from xxx" I've been trying to work out a simple way but can't find it yet. I wish there was a cheat sheet.
For some reason, my 1036 does not like v7 at all. I had to ether boot a few times.

Is there a way to stop filtered routes from populating in the routing table? ie the red routes.
Have you got any sol?

Do you have any tips for reliable route advertisements? I feel like the new filter-based system is clunky.
script, is best and more intuitive
Pretty cool stuff. I just tried to swap my 1100AHxx4 for a CCR1036. Caused a P1 in my house and had to roll back. The cat was very angry with 7.1.1
thx
when is there a video on the bgp confederations?
Otherwise keep it up thx !

What about load balancing using PCC on ROS7.1? Would you be able to do something like that? It would be very helpful. Thanks.
