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

Vlans query
by Steve Hille 28 Nov '16

28 Nov '16

Greetings all, I have a new requirement that I can't quite square away. We use the Metal devices, normally the 2SHPN for wifi, we use Cisco routers and switches and we use Windows servers as our DHCP servers. What I want to do is have the management IP address of the Metal devices on our regular data vlan so that I have layer 2 access in case things go bad, but I want them to supply DHCP addresses to another vlan from the Windows server. Let's say VLAN 10 for data and vlan 60 for the Wifi DHCP range as an example. I don't even know if it is possible, is anyone doing anything similar to this at the moment? Cheers, Steve

/31 IPv4 RFC3021
by Andrew Gilbett 28 Nov '16

Hi Guys, Do any of you know if Mikrotik supports /31 PTP IPv4 links as per RFC3021? Anecdotal evidence suggests that there is some kind of support but not explicit and inter operable support. Thanks Andrew

ROS 6.37 and DHCPv6 client
by Charlie Garrison 25 Nov '16

25 Nov '16

Good morning, Since upgrading to 6.37, router is having trouble getting IPv6 prefix delegation after reboot. Sometimes the dhcp client will finally renew and bind the PD, after 5 minutes or more. Sometimes it fails. Forcing renewal doesn’t help. But if I disable & reenable the dhcpv6 client on the pppoe interface, then it gets PD immediately. Personal observation says there is a timing issue, with dhcp client trying to get PD before pppoe interface is up (but that’s just a guess). Is this a known/common problem? Or an issue with v6.37? What can I do to resolve it? Thanks, Charlie -- Charlie Garrison <garrison(a)zeta.org.au> github.com/cngarrison metacpan.org/author/CNG

Disappearing network - CAPsMAN and 6.37.2
by Charlie Garrison 24 Nov '16

24 Nov '16

Good morning, I upgraded CAPsMAN router from v6.37.1 to 6.37.2 and CAP’s have stopped working. Specifically, the network no longer appears in list of Wifi networks for clients. I can’t find any errors in CAPsMAN router or CAP’s, nor do I see anything relevant in CHANGES. Disabling CAP and using a manual setup (WAP) has bypassed the problem. Of course I need to get CAP’s working again. How do I troubleshoot this issue? Should I reset the router and downgrade to 6.37.1? Something else? Thanks, Charlie PS. I upgraded in (a blind) hope that it would fix an unrelated problem. (I sent a post last month with subject “ROS 6.37 and DHCPv6 client”, but never got any takers.) -- Charlie Garrison <garrison(a)zeta.org.au> github.com/cngarrison metacpan.org/author/CNG

WARNING: Issue when upgrading from versions earlier than v6.22
by Andrew Cox 21 Nov '16

21 Nov '16

Hi All, Just wanted to pass on a quick heads up that Tom Smyth identified. == DO NOT upgrade from before 6.22 to 6.37 versions older than the just released .2 version. *) firewall - fixed "connection-state" value disappearance in rules that were created before v6.22; This also means that if you did already did that, you will need to go in and correct your firewall rules as it will have discarded the connection-state attributes.

Hi Wondering if any one is using 1g copper SFP's in 10G SFP+ port on the 1072's. I just tried 3-4 of mine in 3-4 ports and none of them would register ... rather annoying..
