Re: Feature Request: IPv6 NAT66 Support

IPv6 multihoming without BGP is nearly impossible to do "the IPv6 way", i.e. with two advertised prefixes on the same LAN, from the two routers of the two ISPs. Most people use NAT66 to have a predictable behaviour in case of single failure. I use it with iptables, it is included in linux kernels si...

Re: OSPF Multiarea scenario and redistribuite-connected

I suppose you announce customer /32 in area1 and not in the backbone because you want to limit the backbone database size. If this is not true, how are the /32 announced in area1 and how are they announced in the backbone? Can you post the corresponding /routing ospf lsa print ? Area 0 should be pr...

Re: New : RB760IGS - HEX-S

I would like to know if SFP1 can be *switched* with the other ethernet ports. Looking at the two schematics I understand that SFP1 is either disconnected, or connected to the CPU, but never connected to the switch. Am I correct?

Re: New router OS

Which feature are you waiting for in v7? The one I miss is "completely isolated VRFs": https://forum.mikrotik.com/viewtopic.php?f=14&t=70274#p490199 This includes the tricks that must be done in order to make DHCP relay work in VRFs. I miss this because I use a lot of MPLS L3VPN. I understand that ...

Re: Can RouterOS do Inter-AS MPLS with Option A/B/C?

Some time ago I had to connect a Mikrotik MPLS with a Cisco MPLS for VPNv4 service. I was not brave enough to even think about trying inter-as option B. I did read about the RouterOS difficulties in BGP PE-CE (or inter-as option a, which is basically the same), so I decided to use OSPF PE-CE as the ...

Re: Duplicate VPNv4 default route in bgp (MPLS)

Updates: After some toggling of vlan825 on both core routers, I can see that what this toggling really does is to move the ghost route from one core router to the other. I am now able to reproduce the double route, but still unable to reproduce the connectivity issue. The router with the ghost route...

Duplicate VPNv4 default route in bgp (MPLS)

Today I was troubleshooting an issue where a particular VRF lacked connectivity to all destinations reachable through the default route. The default route is announced via OSPF to a pair of core RB1100AHx2, both with 6.34.6, and they export it to MP-BGP. Both had the default route learned via OSPF i...

Re: v6.34.6 [bugfix] is released!

Upgraded 2 RB1100ahx2 from 6.27 to 6.34.6 with IPsec, GRE, OSPF, BGP, MPLS, VRF, OpenVPN. No issues insofar.

Re: v6.32.4 [bugfix] is released!

I've so far reproduced on hAP lite, mAP-2n, RB951Ui-2HnD. I had this same issue, with the same fix (downgrade to 6.32.3) with RB951G-2HnD. Powering it on with the reset button pressed gives the same result, empty config. I saved the default configuration script with /system default-configuration an...
