MLAG With Mikrotik - High Availability (Full Lab)

#mlag #mikrotikmlag #mikrotik
We'll dive deep into the world of network redundancy with MikroTik switches! Join us as we explore Link Aggregation Control Protocol (LACP) and Multi-Chassis Link Aggregation Group (MLAG) through hands-on experimentation with physical devices.
Our step-by-step lab walkthrough ensures you grasp the concepts and practicalities of LACP and MLAG, enabling you to implement them confidently in your network infrastructure. We'll cover everything, from initial configuration to testing, providing a clear understanding of these essential networking technologies.
Whether you're a seasoned network professional or just starting, this video equips you with the knowledge and skills needed to enhance network performance, reliability, and resilience. Join us for real-world tests from a client end device, and learn how these technologies can revolutionize your network architecture.

Have you implemented MLAG before?

[@biki1973]

can you explain how does that vlan 50 work? how does switch logic know to use vlan 50 to recieve communication from other switch, it isn't set anywhere else

Thanks Wilmer, I'd been struggling with configuring mlag for days now, after watching your video, I had everything working as I needed in a couple of hours. I appreciate you sir. 🖖

[@TheNetworkTrip]

Great to hear!

[@freddyalvarez485]

Like always, outstanding tech approach with Wilmer Almazan.💪🏻💪🏻

[@TheNetworkTrip]

Thank you Freddy!

[@alimibrahem8120]

I spent 2 hours watching this Video and i know that you spent alot more to create such a wounderful content.! so very very thanksful for your effort MR. Wilmer. I genuinely appreciate every moment in it ..! 🙏🌷. now i would like to ask you about the different between L3 hardware offloading and L2 hardware offloading..?

[@TheNetworkTrip]

Thanks!! By the way, the first video about about Firewall rules will come on October 30th!

[@steveedmond7334]

Very good explications. Congrats

[@kirksteinklauber260]

Very nice video!!! Very close to what I am looking for. Is it possible that you can do another one but having the Layer 3 on the CRS3xx switches instead of the RB4011? I am thinking to have VRRP configured on each VLAN pointing to the CRS3xx switches and have a script to enable / disable DHCP if the primary switch is down. I understand that the L3HW Offload is not supported still on this configuration!

[@danliljestig]

I was able to set up between two CRS518 and three CRS312 😀

[@dvreshta]

Very good video. Perfect explanation.

[@TheNetworkTrip]

Thanks!

[@tobiaslang953]

Thanks for the great walkthrough. I really enjoyed it. You mentioned that for a proper HA setup the switches in the distribution layer should get cross-connected to an additional router. How would you configure this?

[@mishasawangwan6652]

great content, very helpful. if i may submit a video request: VRRP with mikrotik! i’ve yet to find much in-depth writeups or videos on this topic. also somewhat related: possible strategies for multi-gateway/dual-wan - i can’t imagine this is a common config but maybe there’s some knowledge you can share regarding it. cheers 🎉

[@TheNetworkTrip]

Great suggestion! I’ll add them to my upcoming video list.

[@jonosadler]

Does anyone know if it works to use a bond (with two slaves) for the ICCP link between the two MLAG switches? Eg two physical links between the switches instead of one. I'll lab up sometime but might be able to save some time if someone has tried before!

[@TheNetworkTrip]

Yes, bonding two links for the ICCP between MLAG switches works. It adds redundancy and bandwidth. Just ensure consistent settings, like LACP for link aggregation.

[@NET-PGS]

Hi, Thanks for this clear concept of M LAG. I would like to request you to let me know that in this case traffic will be flown by both the path simultaneously or flown by any one path at a time? What happen if ICCP connectivity goes down in any case?

[@BPL-Whipster]

To answer your second question, the ICCP peering should itself be resilient. If it goes down, the situation should be that one of the MLAG switches has gone hard down. On an LACP connection, the traffic will be shared between both physical connections. Individual traffic streams might only use one path at a time, but the overall usage should be equal if everything is working well.

[@svschwartz]

Well done! Do you get line rates with mlag? have you tested the throughput ?

[@markobarbaric7434]

Hi Wilmer, where did you find CRS326 image for GNS3?

[@TheNetworkTrip]

Hi Marko, There is no image for the CRS. I’m using physical devices on this video.

[@mikkio5371]

Netowrk Trip i learnt OSPF from zero to hero from you . and that means a great deal to me . but please can you do a vidoe on slaac ,dhcpv6 and static routing on ipv6 using mikrotik . there are no much vidoe of miktrotik using IPV6 address purelly . the world is moving toward IPV6 !! sorry we are asking too much , but it would be pleasing ,if we could see IPV6 soley on mikotik .

[@TheNetworkTrip]

Hello! I’ll have 4-5 videos about IPv6. The first one will come on Nov 01st.

[@DonGrozni]

I have 2 sw(sw1 ------peer----- sw2) mlag setup to core sw. Now i need to add my new aggregation layer with 2 new switches. So my question is... Can I connect another mlag domain new Sw10---peer----Sw11 and setup new mlag to core sw. Sw10,11 will be aggregqtion level and all sw will be connected via mlag lacp connection. Can I do like that or loop will be created? Thx Same network

[@DonGrozni]

After i connect all sw old mlag domain sw1,2 will be deleted peer and I will connect them to new aggregation lvl sw Sw11,12.

[@TheNetworkTrip]

Hello! Yes, you can set up the MLAG between SW10 and SW11 to the core via LACP without creating loops, as long as MLAG and LACP are correctly configured.

[@JaZzDeOliveira]

With this setup , if I was to add 3 more CCR2004 to be my edge switches , would I use a different MLAN ID for each of those 3 additional switches , or would they also be setup with MLAG ID 5?

[@TheNetworkTrip]

Hello! MLAG does not work in that model (CCR2004)

[@JaZzDeOliveira]

Thank you for the quick reply, I understand that , what I meant is following your Lab , if I was to add 3 additional edge devices like the single device you have in your video connected to the PC , would I need to make 3 additional MLAG ID on the CRS326 side for each of the additional units I add to the edge layer? This is for the 3 additional Bonded interfaces that I would be creating on the CRS326 units to accomodate the additional 3 edge units , "if that makes sense 🙂"@@TheNetworkTrip

[@TheNetworkTrip]

Got it! Your are correct! They will be new bonding interfaces, and they will require a new ID each.

[@ricardoduarte9927]

Hi. Can you do non disruptive upgrades when using MLAG?

[@TheNetworkTrip]

Hello! If you need to upgrade a device, it must be rebooted. This means that traffic will only flow through the available switches.

[@ricardoduarte9927]

@@TheNetworkTrip but when the versions mismatch (say, after the first switch is upgraded) will MLAG still work?

[@tristanjohnson9773]

How do I add vlans for devices that are only connected to ONE switch and not part of an MLAG grouping on the two switches? Do I add the same vlan on both switches? Do, I also add the MLAG iccp interface to that Vlan on both switches?

[@wilmeralmazan8824]

Hi, just follow the same process than Vlan 100 (the untagged vlan 100 is not part of MLAG). You can have regular access and trunk interfaces.

[@ДимитърПопов-в1ъ]

I followed all the steps and I get "not hw offloaded". I decided to disable hardware offloading on both switches but this error persist... Is there something missing in the lab?
