What software load are you running? With 7.x you need to define local address.

Found the issue. Rookie mistake.
The microwave radio link was limiting mtu. I increased the mtu on the radio link and the OSPF came up.

gilljr

On the Connection Tab, make sure to assign the local address. I had this same issue and that was the solution.

I have a CCR2116-12G-4S+ running 7.4.1 and cannot establish a second link to another Mikrotik router running v6. The primary link is of network type ptp and is running fine reporting a state of Full. The second link (different interfaces over a different path) will only go into link state ExStart. F...

I am running v7.4.1 and I am seeing this on a link to a router running v6.47.9. I added a second link between the routers and I am getting the same error on the secondary link.

I am having an issue with routers running software release 6.40.8 (bugfix). 1. Cannot create support file. It gets 60 to 80% complete then stops, never writing to the file system. 2.

Do you not need to put Channel-group 1 mode active on interfaces for them to advertise. That was the issue. The Cisco Interfaces now look as follows... interface Ethernet1/17 switchport mode trunk switchport trunk allowed vlan 206,607 speed 1000 channel-group 1 mode active interface Ethernet1/18 sw...

Do you not need to put Channel-group 1 mode active on interfaces for them to advertise.

That maybe the issue. I am going to move the traffic off of the bond and see if I can fix it and move the traffic back.

gilljr

As you have bonded the two ports on the switch you may be experiencing and issue with STP and RSTP. have you tried connecting just 1 and seeing if traffic flows? I have Spanning Tree Disabled on the VLANs. It is traffic originating from the Mikrotik that is going only on one interface. Traffic from...

I found a previous post relating to this subject that did not answer my issue...https://forum.mikrotik.com/viewtopic.php?t=110400 I am using a CCR1036-12G-4S (6.37.4) and bonding 2 SFP modules to a Cisco Nexus 3064 switch. The bonding does not seem to be working properly. I expect it is an issue wit...

I have now resolved the LDP issue. A reboot did not resolve the issue, but placing advertising filters that only advertise the loopback addresses did. I must have to many addresses assigned to my routers. My VPLS tunnel is also now establishing which is great. If someone else has some issues getting...

gilljr

I would use policy based routing. You tag the flows with mangle and route on the tag. There is a use case on my network that I had to do this where a small segment of traffic does not flow over the OSPF best path.

I captured the packets on the link between R3 and R6 at R3 and looked at my capture using wireshark. I do not know exactly what I am supposed to be seeing, but I am only seeing the addresses sent from R3 to R6. Below is a look at my capture.

RouterOS 6.32.4 on both sides MTU set to 1508 I had a previous posting where I talked about not being able to ping R6 when I enabled the LDP interface on R3 and R6 and neighbors were discovered. That is no longer my issue. Now when the neighbors are discovered I am having 2 issues. 1. The LDP neighb...

gilljr

I modified the MTU and made all the OSPF routes intra area. Now I no longer lose traffic when enabling the LDP Interface, but I still cannot establish a VPLS tunnel. I am ending this post and starting a new one "LDP Neighbor - No Addresses" as that is my problem now.

gilljr

Do all the routes need to be Intra-Area or can I have a mixture of Intra-Area and External Type 1? That is the only thing I can think of. I do not list all the network addresses in the OSPF networks tab, instead I redistribute static and connected.

gilljr

I have a network that has multiple routers running OSPF that I am slowly enabling MPLS on and I am having some difficulty. I am going to be adding a second VPLS network so I have to expand the number of routers with MPLS enabled. All of my routers use a loopback address for OSPF router ID as well as...

I found that if my local address in the dhcp-relay is one of the IP addresses on the interface it will work if you use the "shared-network" command on the DHCP server. shared-network SharedNetworkName { subnet x.x.x.x netmask y.y.y.y { ..... } } subnet z.z.z.z netmask w.w.w.w { ..... } } }

I know this is a basic question, but have you tried the same ports that work with the newer windows boxes with the linux and xp boxes.

gilljr

These switches are not intuitive at all to program but once you have done it a couple times it is easy enough. Below is an example on how you could do it. My example uses ether1 as the master switch port and trunking port. VLANs 10,20,30,40,50,60 are the 6 VLANs and 10 is the management VLAN. First ...

I have been using DHCP relay with Mikrotik and a Linux box for years. My question is can I relay 2 different subnets on the same interface via dhcp-relay. I know that if the Mikrotik is acting as the DHCP server it can use a pool that leads to another to do what I want, but I centrally manage DHCP a...

I have now begun seeing this same error between 2 of my CCR (1009 and 1016) routers at random times (a handful of times every 3 days) in Point-to-Point OSPF mode. The errors are showing on both sides of the link but not at the same time. The routers are both running 6.30.4 and are connected via a Me...

gilljr

I would not recommend running 6.32.2, but rather 6.30.4 which is the bug fix version if you are in production. I find it to be very stable while I have had some issues with versions both above it and below it in my testing.

I have ran fiber up a tower before. Typically I only do it for one of two reasons... 1. Long run (Ethernet is 100m) 2. Powered tower and do not want RF to enter my data transmission I use armored fiber cable and usually bring it into a NEMA enclosure through a waterproof gland and terminate it norma...

gilljr

Your trace route looked good. As the other person who posted stated, it looks like you have either a virus or maybe are sharing a torrent behind your router. I would suggest torching the LAN side of your router and see if there is a device that is sending a lot of traffic.

gilljr

I utilize a centralized DHCP server and am having issues with using DHCP relay with NAT. If NAT is not involved, DHCP works great. I am not worried about security since the whole network is private that the DHCP requests are going over. Can I get this to work without setting up a VPN to bypass NAT o...

We ended up switching to banance rr to send traffic over both links. At this point the traffic looks good and I am not seeing any issues.

The bonding interface is bonding 2 vlans. I would only bond 2 interfaces, but I need to manage the Microwave links. So the Vlans are not on the bonding interface. I question was how do I get the traffic to evenly pass over both the microwave links. 802.3ad does not seem to work since the link is poi...

I have two 300Mbps Microwave links joining 2 sites together. One site is just a relay point to get bandwidth to the other site. On either side I have CCR routers. Because the radios are inband managed as configured, I have the radios listening on one vlan and a different vlan configured for passing ...

The issue was the Metro-LAN service. The carrier that I was using actually fixed the issue within their network that was causing the reflection and the short time that I was switch to NBMA I had no drops or errors.

Thank you for the help.

gilljr

You seem to imply that this is a new fiber setup to a new site. You might try a NBMA neighbor setup so that multicast is removed from the equation. If your fiber is some sort of metro-LAN service, you might be seeing the multicast reflected. Joe It is a metro-LAN service from a carrier I have never...

I am experiencing a Core Dump on my CCR router when I add 2 interfaces to a bonding group, remove the bonding group, and then finally attempt to add one of the interfaces that were part of the bonding group to a bridge. Has anyone else seen or experienced this bug?

I figured it out.
I created a policy for the block that I did not want encrypted and in that policy I set the following which can be seen in the attached image:
1. Action=none
2. Level=use
3. Priority=1 (greater that the policy for the main block).

From my previous response, I would change the following:

You would assign 2.0.0.2/32 to ether1 and add a route of 0.0.0.0/0 with a gateway of ether1.
/ip address add address=2.0.0.2/32 interface ether1
- and -
/ip route add dst-address=0.0.0.0/0 gateway=ether1

gilljr

I actually misread your post. You have a /32, not /30.... I will post another answer for the /32. Lets say your WAN block is 2.0.0.0/30 and your LAN block is 1.0.0.0/24. Your ISP is using 2.0.0.1 and they tell you to assign 2.0.0.2 to your interface (lets say ether1). You would assign 2.0.0.2/30 to ...

That did solve the issue. I am now getting accurate values. Now this is only for the spf interfaces, correct or should this be also used on all gbit interfaces?
