Hey guys, please use the below reference material to get the most out of watching this video. Thanks again for the great cheat sheet created by Rick Frey! One important note that I would like to leave that I forget to mention inside of the video is that when it comes to route filtering, please try and create separate in & out filters PER peer/connection. If you create just one filter that is used across many peers there will come a day that you need to make a change that will only impact the one peer but now it will affect many. It is considered best practice to setup filtering in this manner.

oh and thank you again J. !! now totally into BGP stuff and also peered with 2 ciscos yet convinced my boss even to buy 2 CCR2116 for our internet peering routers :) hope you are going to do mikrotik stuff again soon
That's awesome, yeah I will still do MikroTik stuff as well, there's definitely a few more things that I can cover when it comes to BGP. Might also need to look at revisiting some topics that have changed in v7 for my MTCNA/MTCRE materials.
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.
Hello, I put 2116 as a border. I configured filtering, but I am not sure that the bgp bgp communities attribute is not transmitted within my router between my bgp peers. Record a video on bgp communities. For my part, I can draw a network diagram as it is built for me under real conditions
I have been experiencing weird issues with CCR2216 running V7.13. That when I open ip routes to see all the bgp routes, my winbox just freezes and when I try to filter out blackhole routes that i created, it doesnt show. Does this happen to you?
Very very thanksful for your deep explaination man. All love and respect..! Well i have a question for you. So in the ROS router board, if the internet connection came from port 1, and i want the internet in all other port, so what i usually do is building a bridge between Eth1 and all other ports. But some people say that this is not desirable, it is recomended to build a NAT rule between Eth 1 and all other ports so the outside interface became a kind of separate from other one, So is this true..? Or that is doesn't make sence..? Please advise me.
huh i didn't know i could use multiple rules for the same chain in a top to bottom fashion, i was configuring my filters all in a massive rule using recursive if statements and else statements. i wonder if there is any appreciable difference performance-wise between the two methods.
Your method sounds really good too, I'm really not sure what the performance differences would be. I'm thinking quite minimal but I am really just guessing. So would need to get some answer directly from MT.
My actual OS is Win11, although I love working on Ubuntu in a work setting so I have an Ubuntu VM running off of VMWare just for that purpose. The default terminal client on Ubuntu works just fine for management :D!
