Re: DHCP Option 82 / DHCP-Snooping

Hi, does someone use Option82 in production with Router OS? I was playing a bit with Option 82 on RouterOS, it works fine, just doesn't send the VLAN number. I have a Router with Bridged ports with HW offload (acts as a switch). Relay is running on it. Ether1 is connected to DHCP server location. Ph...

Re: v6.42rc [release candidate] is released!

Ok, guys, I have found the answer on my previous question. :-) Final solution is not that automated as I wanted, but still better than nothing. Instead of setting 0.0.0.0 to profiles we should do following : 1. Define different IP pool for profile. For example 192.168.101.0/24 - regular users, 192.1...

Re: v6.42rc [release candidate] is released!

I checked to override with Radius remote user PPP profile ("Mikrotik-Group" attribute) - it works fine. This is a nice feature that some people where asking for a long time. Now we can define several profiles and set different values there, such as speed per profile, queue type, different pool and t...

Re: User logged out after CoA

Hi, it depends what sofware are you using.
We have https://splynx.com working fine with COA and no issues with it. Mikrotik has sometimes bugs, like in Radius with 6.39.0 version, but they fix quite it quickly

Interfaces with no-queue values

Hello, I have a strange behaviour of routers in one of my networks. Interfaces are put by router without any reason to interface queue "no-queue". What we see is that customers connected to the routers with no-queue interfaces are complaining for speed limitation, and we found that the interface spe...

Re: eBGP / iBGP configuration questions

Question 1: Should I use the same BGP instance for both eBGP and iBGP? Yes, you can use one instance, when you have one AS number, there is no need for second instance Even if you will use one instance still the distance will be 20 for eBPG and 200 for iBGP, but I'm not sure about behaviour and whi...

Re: RouterOS Virtual Labs

Hi, yes, the first small issue - after installation you need to update version of unetlab to latest one - just run commands apt-get update && apt-get install unetlab I think they will fix it soon. Second question - when you add Mikrotik to Unetlab, you must chose "VNC" as type of default connection....

Would be great to see that too and your thought comparing gns and unetlab. Thanks Hi, Unetlab is an awesome software, GNS3 cannot compar...

Re: How to put dynamic interfaces to specific VRF

Hi lahoras, look - there are 2 dimensions of managing BGP traffic : 1.
