Please be aware!

One more Mikrotik CHR, working on other vmware environment (5.5) has been powered-off without any errors during veeam backup tonight.

This one has CHR version is 6.45.7 (1cpu, 128ram).

Looks like 6.45 has stability issues with vmware

Hello! I installed CHR, hardware and x86 RouterOS many-many times, with CHR mostly on vmware virtualisation with no issues but most recent deployment with version 6.45.8 was buggy Two times router frozen, and once just shutdown without any issues or warns. There are hundreds of reasons of cause, but...

Hello! I am looking for the Best practice experience for upgrading of >50 routers on my corporate network.

We are on 6.45.x with RB1100AHx4 and HEX hardware. Mostly using IPSEC and BGP...

Any ideas&advices how to upgrade in smooth way?

Hello,

Does anyone faced with same problem?

Stable 6.45.3-6.45.7 hardware mikrotik instalation (new router) do not accept my login from ROMON and Mac-Telnet - "wrong password"

In the same time no issue to login via winbox. I have already two devices with same issue

Same issue for me! With tcp retransmissions and very slow tcp transfers from/to mpls chr

Hyper-V works because it does not assemble packets into 64k buffers. But this assembly happens only for traffic which source and destination is also virtual guest. If destination is physical router outside VM environment then there should be no problem with MPLS. I can confirm the issue is still he...

I can confirm same issue with TCP sessions over EOIP links with or without IPSEC

No solution or workaround have been found so far

Hello, Is anyone have experience to solve limitations of the L4 license for the routerbord? The HEX have L4 license that mean the limit of 200 L2TP sessions per device. https://wiki.mikrotik.com/wiki/Manual:License Do the limit above applicable for the routerboards? Can I upgrade the license from L4...

If I remember correctly, inter AS MPLS will work as long as you enable BGP multi hop over OSPF and run LDP between the two peers. While this isn't the same solution you using with the Cisco routers, it should allow you to exchange labels. May I ask you to make more clear statement? The LDP do not p...

From presentation,Tomas sad:

Thanks, nichky. When it was presented? Last mum in Milan?


UPD: This is old slide from 2013, that is not fully correct anymore.

L3VPN works fine within one AS

try to debug l2tp on both client and server.

May this can help you with new ideas

Try to put "allow all" rule for input for both client and server (disable firewall for test)

Still no solution known... Anyone?

I suggest you to start without ipsec, and when it will be done, restart with ipsec enabled.

Please check that you ipsec settings are clear: no records in ipsec polices except one template rule.

l2tp use one UDP port 1701

fix your firewall to allow l2tp on both wan1 and wan2. Did you use ipsec as well? Allow ipsec if in use by udp 500 and udp 4500 port and IP ESP protocol as well Where is you vpn server located? inside lan or on router? What this rule do for you? add action=dst-nat chain=dstnat dst-port=1723 in-inter...

Hi,

I am managing both AS and try to implement Inter-AS based on mikrotik to build L3VPNs between AS.

I updated screenshot so you can see that is a lab environment build on eve-ng

Guys,
I can share this lab with all settings to play with MPLS on your equipment

Hello, Mikrotik guru! Can RouterOS transfer MPLS Labels between AS? This is a screenshot from simplified lab environment with border routers connected directly.

The update with solution: There is wrong idea to use OSPF virtual links. This feature seems to be broken in mikrotik and in same time CCIE person had not recommend to use OSPF virtual links at all The such complex scenario will be much better to be handled by BGP. Here is updated picture https://i.g...
