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

Vlans query
by Steve Hille 29 Nov '16

29 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 29 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 25 Nov '16

25 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 22 Nov '16

22 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..

bgp question
by Alex Samad - Yieldbroker 14 Nov '16

14 Nov '16

I have 2 border routers that mesh connect to 2 vendor routers on their own vlan. The border routers connect to another pair of internal routers on another vlan. So bdr => vendor eBGP bdr => internal iBGP I have bgp peers connected bdr -> internal Now I am only seeing a very limited range of prefixes. 1) I think my aggregate is affecting my iBGP 2) I think my outfilter on my instance is affecting my iBGP as well I thought iBGP would be treated differently. I am thinking of instead of sharing my AS between inside and the border I create a new private AS. As I don't want to change my BGP filters Alex
