UPS Serial Cable
by Paul Julian 29 Jun '17

29 Jun '17

Hi guys, we have got some APC UPS's with the serial DB9 connections on them but need to connect them to Mikrotik RB2011 and RB1100AHx2 models. Does anybody have any suggestions on a cable to suit ? The problem is they are both setup to be the B end of the situation and not the MT setup to be the A end and the UPS as the B end. I was thinking of a gender bender but don't really want to do that if I don't have to..... Any thoughts would be appreciated. Thanks Paul

OSPF redistribute-connected in a VRF?
by Damien Gardner Jnr 30 Dec '16

30 Dec '16

Hey Folks, So my project while on my week off from work has been to build Miss 7 a PC. Which takes a lot more work than you'd first think, since I want it behind something doing a LOT of filtering :D After a lot of playing, I ended up with a Sophos UTM. Those things are very cool, and they provide a free virtual appliance license for home use, so I ran it up in Xenserver, and it's working a treat. Finished the computer yesterday, and today I sat down to quickly run a VRF up between home and the DC (where the UTM is running). The kids now have their own vlan at home, instead of being mixed in with the missus and I, and all our various devices (you know, the usual, xbox, wii, various roku players, the bathroom scales, etc ;). We already have an EOIP tunnel with a few vlans between home and the DC, so I just created one more, popped it into a VRF, and created a new OSPF instance. And then things fell apart ;) So Home Router can see DC Router and vice versa over the EOIP Vlan, OSPF comes up. And then the connected routes on each end do not show. SHOULD this work? I can do static routes if I have to, but I want to do a mesh config with two routers at each end (VM's for pure tunnelling grunt, being backed up by the CRS-109's at each end when the VM's are down), so OSPF would make things easier.. I've disabled my default OSPF instance on both ends for now to make debugging easier. My config looks like: Home End: /interface eoip add allow-fast-path=no !keepalive local-address=<HOME_RTR_IP> name=EOIP_SY3_PRIMARY remote-address=<SYD_RTR_IP> tunnel-id=1 /interface vlan add interface=EOIP_SY3_PRIMARY loop-protect-disable-time=0s loop-protect-send-interval=0s name=VLAN_EOIP_SY3_KIDS vlan-id=42 /routing ospf instance add name=ospf_kids redistribute-connected=as-type-1 redistribute-static=as-type-1 \ router-id=192.168.12.18 routing-table=KIDS /routing ospf area add area-id=1.1.1.1 instance=ospf_kids name=area_kids /ip address add address=192.168.12.18/28 interface=KIDS network=192.168.12.16 add address=192.168.10.26/30 interface=VLAN_EOIP_SY3_KIDS network=192.168.10.24 /ip route vrf add export-route-targets=65535:102 import-route-targets=65535:102 interfaces=KIDS,VLAN_EOIP_SY3_KIDS route-distin 65535:102 routing-mark=KIDS /routing ospf interface add interface=VLAN_EOIP_SY3_KIDS network-type=broadcast /routing ospf network add area=area_kids network=192.168.10.24/30 DC End: /interface eoip add allow-fast-path=no !keepalive local-address=<SYD_RTR_IP> name=EOIP_WYONG_PRIMARY remote-address=<HOME_RTR_IP> tunnel-id=1 /interface vlan add interface=EOIP_WYONG_PRIMARY name=VLAN_EOIP_WYONG_KIDS vlan-id=42 add interface=vlan41 name=vlan42_KIDS vlan-id=42 /routing ospf instance add name=ospf_kids redistribute-connected=as-type-1 redistribute-static=\ as-type-1 router-id=192.168.10.25 routing-table=KIDS /routing ospf area add area-id=1.1.1.1 instance=ospf_kids name=area_kids /ip address add address=192.168.12.34/29 interface=vlan42_KIDS network=192.168.12.32 add address=192.168.10.25/30 interface=VLAN_EOIP_WYONG_KIDS network=\ 192.168.10.24 /ip route vrf add export-route-targets=65535:102 import-route-targets=65535:102 interfaces=\ vlan42_KIDS,VLAN_EOIP_WYONG_KIDS route-distinguisher=65535:102 \ routing-mark=KIDS /routing ospf network add area=area_kids network=192.168.10.24/30 If I show the OSPF routes on the sydney end, I only see the EOIP VLAN /30, and the local /29: [someguy@MikroTik] > /routing ospf route print detail 0 instance=ospf_kids dst-address=192.168.10.24/30 state=intra-area gateway=0.0.0.0 interface=VLAN_EOIP_WYONG_KIDS cost=10 area=area_kids 1 instance=ospf_kids dst-address=192.168.12.32/29 state=imported-ext-1 gateway="" interface="" cost=20 area=external Any thoughts?

Wireless at a Distance
by Dave Browning 23 Dec '16

23 Dec '16

Lads, Any Mikrotik device suggestions for a device we can set on a wall that’ll service WiFi clients about 40 metres away in one direction. A P2P link with a station in the middle of the serviceable area isn't an option currently, I know would be better solution.

positioning filter rules
by Karl Auer 13 Dec '16

13 Dec '16

I have a script that adds filter rules. The rules are the sort that need to precede others, so I have "place- before=0" in the script. Mostly, that doesn't work. It fails with this message: the item referred by 'place-before' does not exist (11) This is demonstrably untrue. There are plenty of rules. It *seems* that if I manually print a rule listing before running my script, this error doesn't happen. That's not a useful solution... Stumped. Ideas?

RB1100 Rack-Mount Ears
by Ben Farmer 12 Dec '16

12 Dec '16

Hi guys, We've had a few RB's come back as of late with missing ears (I'm not sure what the techs do with them, I think they get hungry). Does anyone know of a business that sells these sorts of spares? It looks like a few in the US sell them, but I'm hoping someone local has them. Cheers! Regards, Ben Farmer

RANCID with Mikrotik Devices
by Darryl Ross 06 Dec '16

06 Dec '16

Hey All, Wondering if anyone else is using RANCID to back up Mikrotik devices? I'm having a strange issue where 7 out of my 20 devices are failing to be backed up when RANCID is run by cron, but work without complaint when run manually on the command line... The devices include a few different models (CCR, CRS, RB) but all are running 6.37.1 - as are the devices that are not failing. Other devices including Cisco, Brocade and HP-VC are all working without issue. Any insights might save my remaining hair! -Darryl

ccr connections to switches
by Alex Samad - Yieldbroker 02 Dec '16

02 Dec '16

Hi I have 6 ccr1036's in pairs of 2 LACP'ed to stacked Dell 8024F & 8132F switches.. These are about to be replaced with arista 7050sx switches in MLAG config. I have previously setup the CCr1036 as STP edge devices, so portfast and spanning tree disabled. But I have recently had 2 ccr's do death reboot cycles, crash and then reboot themselves in loops. This has cause lots of problems for my OSPF network :) I presume they have DR or BR at the times - unlucky me. I notice I with LACP there is RSTP turned on. Which got me thinking maybe I should have them configured on the switches as No portfast No span disabled And make them go through a spanning tree block , learn, forward states. Just wonder how others have their ccr's connection - especially if you have LACP connection Alex
