CRS312 NO SFP (SX/LX) LINK with Nokia/Alcatel after upgrade from 6.49.7 to 7.9.1 In one of our CRS312-4C+8XG we have a backup link using SFP S-85DLC05D connected to an Nokia(Alcatel MPLS router 7210-SAS-M When we upgraded to ROS 7.9.1 the link doesn't establish anymore. Behavior (before and after up...

I've had an OSPF instability due to duplicate router-id's in the network when migrating services from one old router to a new (v7.x) one. The problem was originated because I've included the loopback address from the old router in the new one. I've intentionally placed the address in the disable sta...

It seems Google decided to drop all the remaining VPN protocols from Android in version 13 After upgrade the devices only show 3 variants of IKEv2 (MSCHAPv2, PSK and RSA) the old ones PPTP & L2TP/IPSEC are gone! In a large scale "enterprise" deployment like ours (Lisbon Polytechnic) wi...

Hello, I have some use cases that require some static routes kept local to the device and other static routes redistributed via OSPF. In ROS 6 the solution I had was "tagging" the static routes with some special ( 65511:1 ) BGP community and then using a routing filter on ospf-out that fil...

I'm also thinking about his usage as a router inside the virtualization servers to enable an independent and practical way of connecting "distant" services with VM's using some kind of tunnels or VPNs to routers. I have some questions about the product that aren't explicit in the product p...

Hello,
In the last week a few protocol and implementation flaws were revealed affecting almost any manufacturer.
Is there any information about the affected Mikrotik products and solutions?
Regards.

Thank you for that detail I was missing ... I've confirmed that the "Tx Power" raises to 18dBm when I disable one of the Tx chains. The "Total Tx Power" remains at 18dBm in this situation. So I'm concluding that when configured to some regulatory domain with "Tx Power Mode&q...

Is there any simple way to obtain the SFP data (serial numbers and DDM info) for all the SFP modules installed in one equipment? A complex script iterating thru all the SFP interfaces doesn't seem practical. Some print command (eg. /interface ethernet sfp print ) should print a summary about each SF...

After some complains about frequent drops in our dialup VPNs, we have made a test and this are our current conclusions. When the user connects, the Mikrotik (CHS) receives the answer below from the FreeRADIUS. The user navigates in the web and maintains an active "Spotify" streaming active...

RouterOS 6.42.1 While debugging a user connectivity problem I've found the SSH CLI is sometimes reporting a wrong speed in interfaces. This is correct (10M) and consistent with the information provided in the WEBFIG: > /interface ethernet monitor 13 name: ether14 status: link-ok auto-negotiation: do...

After noticing our recent acquired CRS112s weren't using the HW offloading in the bridge ports, I've done some tests and found that happens after activating the IVL (VLAN filtering) at the bridge level. By default, with RouterOS 6.41.3 the HW offloading is active (note the "H" in each swit...

I've received information from our main Mikrotik supplier that CRS328 (24 PoE AF/AT) is already in production/sales. The supplied product flyer doesn't mention the L2 IPv6 support capabilities, of course the L3 functions will be available as in other RouterOS products, but, does de equipment (and th...

Also waiting for the PoE switches here, I'll have to buy from another brand if they aren't released in January ...

In interfaces using VRRP, I'm seeing a lot of "duplicate" entries, ARP broadcasts and connectivity delays This is what I've concluded in my analysis of the situation: Routers do their direct deliveries on the base (non VRRP) interface, using the interface MAC address in his ARP requests (e...

To ease the management of IPv6 networks is useful as a first step to base them on the existing IPv4 network structure. One of the things that could be done is using some elements embedded in the IPv6 link-local address so the Windows "ipconfig /all" (and alike from other OSs) provide an si...

It should be very simple to add support for selecting the bits of the IPv6 RA that announce if the router have "High", "Medium" or "Low" preference for being selected as a default router for the terminals in the segment. (RFC4191 2.1 Preference values) I know VRRP could...
