Now that ROS7 is here although without BGP lets keep our fingers crossed for flowspec support.

mhugo

Hi! We have 100s of HEXs at customer sites in our network and we basically use them as managed ethernet converters so customer traffic is just bridged to reach larger routers at central sites. On top of that we can monitor them and see that the customers are up. Please make something similar with a ...

Hi, I have a couple of 317s behaving in the same strange way for 2 things I have seen. They are in different locations and run 6.45.6. Important is that I have at least 4 units with the same symptoms as below so I think they might be related and caused by software or some issue in hw batch. 1) Free ...

mhugo

317s quite broken with no multicast (romon or ospf). Testing 46rc16 and then downgrade to 44.5 required hands on reboot probably to flash down firmware. Links came up but no ARP.

mhugo

Upgraded from 6.44.5 to 6.45.2 and now I cannot login to the CRS317 using ROMON since it suddenly sees no neighbours and OSPF doesent find a neighbour. Downgrade to 6.44.5 solves this, but not the autonegotiation issue we have on 317s with 1 gig SFPs that was introduced in 6.43 when Mikrotik impleme...

mhugo

Lots of wierdness in this release on 317s. Working OSPF stops working - neighbour is not seen from 317 but adjacent 1016 sees ospf neighbor. Romon stops working. Downgrade to 6.44.5 works but that breaks some of the SFPs with autoneg that was broken until 6.45 in 317s and early 6.42.x with old auton...

Hi,

On CRS317 two SPFs working in previous version is not seen by system anymore.

Yellow bidi is seen for uplink thank god, but blue is not there any more.

/M

mhugo

We also need this - +1

mhugo

Hi,

The reason is that the optical link was too long, so im using a CRS317 to repeat the signal. It should not do anything but forward packets to the other port. I dont know if a port mirror could be used?

/M

mhugo

Hi,

We are trying to use a CRS317 to repeat a wave that required more than 80 km laser. The customer wants us to forward LACP, but it seems the CRS is not doing it.

Is there any way I can bridge two interfaces so seamlessly that LACP is forwarded?

/M

mhugo

+1 from me too. I could live with slow commands as long as the convergence is at least somewhat faster. We have been hoping for year now, but now we are getting closer and to desperation as the table grows.

/M

mhugo

+1 for just fixing this. /31 and two /32s are different usecases.

We use /32s for end users but we would like /31 for core backbone links and uplinks - gets ugly injecting both /32s from MT and /31s from non MT equipment.

mhugo

As other people wonder - Are we/Have we gotten hardware support for QinQ?

mhugo

My wish for V7 is basically better BGP performance since my routers are maxing the core it runs on all the time. Besides that I need to be able to set circuit id in DHCP request would be great with possibility of running a script when assigned/deassigned to configure central interface with the lease...

mhugo

We have been waiting too long for basic SP features like multithread BGP and something as simple as DHCP Option 82 Circuit ID. I think that if Mikrotik showed that anything was actually happening it would be easier to not look at other vendors.

mhugo

Hi,

Is it just me or did the new bridge implementation just vanish in 6.41rc50 - On CRS212-1G-10S-1S+ Im back with masterports and no hardware offload in menu?

/Mikael

mhugo

Seems to be some chip issue when adding vlans in bridge on 212. Verified by Mikrotik trainer who will contact MT tomorrow.

mhugo

Hardware offload for Vlans using the bridge ports on CRS212 does not seem to work? /interface bridge add igmp-snooping=no name=bridge1 add igmp-snooping=no name=bridge2 /interface vlan add interface=sfp10 name=sfp10-vlan100 vlan-id=100 add interface=sfp10 name=sfp10-vlan101 vlan-id=101 /interface br...

mhugo

BGP Route Reflector support not installing the routes would be nice.

mhugo

Hi, You can use 1.1.1.1/32 and 2.2.2.2/32 as example. Router A is 1.1.1.1/32 so as the ip you add 1.1.1.1/32 with broadcast of 2.2.2.2 Router B is 2.2.2.2/32 so there you use 2.2.2.2/32 and broadcast of 1.1.1.1 To route 0.0.0.0/0 to router A from router B you add a route to 0.0.0.0/0 with gateway 1....

mhugo

Hi, We started assigning IPs to customers using DHCP and giving them a /32 ip and providing a different gw also as a /32. This works fine for the couple of routers we tested on, but now a new customer with limited skills and far away says its not working even if we can see the address is assigned an...

mhugo

Thank you for the effort but this is only with dhcp relay and not per interface. Coupled with portable /32 requirement backed by radius its just so that routeros is too weak right now. Think solving this before going into full TR0069 solution would have been better path. Basically we would like to h...

mhugo

Hi!

Any luck with this? Im looking for the same kind of solution.

Im considering one dhcp server per port right now, but that feels very unscalable.

/Mikael

mhugo

Did you manage to figure anything out? I think it would be great if we could us Option 82 in the HEX Cpe in dhcp relay mode wth circuit id that we can set to the line-id and connect with dhcp/radius.

mhugo

I was unclear on what I meant. Assigning a /24 via DHCP does not add the route and with no route OSPF wont announce anything. If /24s are assigned scattered over a routed network static routes would be needed for each /24 and then using ospf. I was asking if anybody had good scripts for the DHCP ser...

mhugo

New routing engine is a big expectation together with multicore bgp. That would be great

/Mikael

mhugo

Hi, Im planning to implement a network assigning /24s to customer using radius enabled dhcp from same subnet all over the network so it is not part of a bigger subnet in each router. Has anyone succeed in a good way to add the routes into the central routers table when an IP is assigned? I think the...

mhugo

Hi,

Does anyone know of an LTE (preferably pci-e) that works in Mikrotik?

SXTLTE would be great but does not support 450 band.

/Mikael

mhugo

Hi, We are actively investigating a GEPON architecture and despite being a heavy Mikrotik user for many years this is making us look at alternatives on central nodes. I agree that BIDI is cheap and efficient, but it fills a lot in volume on central nodes and requires singlefiber per customer (espcia...

mhugo

Im still hoping for dhcp client to make it easier to deploy in the field as customer CPE. We want the dhcp client for the management network.

mhugo

We really need this since we are low on IPV4 and use a lot of /32

mhugo

Hi,

I would also say it would be ok for us if the 1072 was released with ROS 6 and have performance limitations. We are delaying builds where we would like to place 1072s to make it futureproof.

mhugo

Needed +1

mhugo

Reboot solved it. IPV6 does not seem 100% stable.

mhugo

Hi, Were finally putting in ipv6, but we have issues with our upstreams since they provide smaller networks for the links than /64. In mikrotik it says unreachable and we cant ping them. If we use the link local fe80 then it works and also the links carry ipv4 without any problem. Its a CCR1036-12G-...

mhugo

+1 (Its not replacable with auto.rsc)

mhugo

Hi,

Great with th SFP+ cloudcore - Any chance of getting a version with SFPs instead of coppergigs.

Would need 10 immediately

/Mikael

mhugo

We have made some investigation into the issue now, and it seems it has to do with when the links change.

Like switching port and moving the ip along, the system crashing and booting, etc.

So im guessing there is a small issue somewhere in the internal code making the LSAs wrong in these conditions.

mhugo

Hi, We are having the issue sometimes - Our observation is that this only happens on routers with one ospf uplink but on all kinds of routers. Right now we have managed to reproduce this error on a router not carrying any traffic and the ospf has been cycling for 2 days. The routers are connected on...

mhugo

Hi,

We get kernel errors booting ROS6 on Xenserver - Version 5 is working.

/Mikael

mhugo

Sudden master flags wrong and the ospf recalculates many times before stabilizing and sometime triggering a crash on one of the OSPF routers.

100% Mikrotik OSPF network with some IPv4 BGP.

There are some threads on this which MT has been very absent on.

mhugo

+1

We want to roll out like 80 cloudcore routers in our DC but with the current state of OSPF we will be getting too many issues we feel.

mhugo

We dont have any duplicate router ids since that will cause a mess

mhugo

We would like it too - we use it a lot in our hyper-v enviroment.

mhugo

DHCP client is working like 25% of the time even on factory reset unit with only dhcp client enabled on ether1 on 750G

mhugo

Sorry for crossposting -

I have the issue too and it seems to be originating in one router as two neighbours gets the master flag changed issue.

The router has been switched two times 732->RB1100->RB1100X2

Routerid has been checked, no visible network issues on the ethernet , etc.

Any clue?

/M

mhugo

Hi, I have this problem in 5.18 - One box looses two ospf neighbours at the same time and the other neighbours sees that there is a different master flag. Since this happens at the same time with two directly connected neighbours its little wierd. Routers are using a unique (checked too) ip on a loo...

mhugo

Hi,

Is there any way to run an ethernet bond from one server to two mikrotiks so that it wont fail if a RB1200 goes down for an upgrade or power is lost?

The server is running XEN with a lot of VLANS terminated into the RB1200.

/MH

mhugo

Im very interested in knowing if it works too.

Anyone knows if the RAM can be upped from 512mb?

mhugo

Hi! I have a couple of services running on dedicated public IPs with static NAT. Everything works fine from the Internet, but internal machines cannot reach the services on the external IPs. It seems Im not getting any traffic back. Here is a dump frommy firewall MT running 3.15 - All hosts are conn...

mhugo

Running 2.9.38 - Upnp is enabled but is not detected by either vista or any other app as a upnp device.

upnp is enabled and not firewall filters are in place - just plain nat enabled.

Interfaces are tagged internal for all but the external.

Any idea what is broken?
