Be sure that you have some thing like this in your config . /routing filter rule add chain=ospf-in disabled=no rule="if (dst in 10.29.0.0/24 && dst-len in 24-32) { set pref-src 10.29.0.1; accept }" where 10.29.0.0/24 is a loopbacks range and 10.29.0.1 is loopback ip installed on RT.

vpn4 broken in ros7. ie better to say it is partially broken.
staitc routes not distirbute
leaked routes not distribute
blackhole not distribute

uCZBpmK6pwoZg7LR

update #2: after restarting BGP again, the CRS309 is again not receiving any routes. nothing in the config has changed other than adding a new local IP address. I have it as well even between different mikrotiks on 7.15.3. routes from another ibgp just ignored but in my case also vpn4 route multipl...

uCZBpmK6pwoZg7LR

Gentlemen, what is the difference between firmware V6 and V7, which is better? For basic stuff like home router better to move to 7. For advanced like MPLS VPN4 etc better to stay on 6 yet because still a lot of issues not solved. But it is also depend . Some function works good some features in ro...

Any plan to fix VRF export static routes over bgp ?

uCZBpmK6pwoZg7LR

It is not entirely true, PE can still be protected and client behind PE as well. Only thing that you cannot do is destination nat on traffic from MPLS cloud to CE. DNAT to local interface(bridge assigned to vrf works) "works" is too loud word in that case, at least it reach PREROUTING, FO...

uCZBpmK6pwoZg7LR

Thank you very much for your concerns and bringing it up to the attention. v7 is now using new linux kernel with proper VRF implementation, which of course will lead to completely different operation principles. VRF has its own vrfinterface which is used as a loopback for all the traffic that needs...

uCZBpmK6pwoZg7LR

I can say even more since ros 7.14 it will be no firewall in PE routers . PE-CE segment will be not protected. will be not possible to SNAT and DNAT VPN4 traffic on PE router.

uCZBpmK6pwoZg7LR

Hi guys. I think it is time to move that to public. We started to worry about future of mikrotik. Look like that they lost their leading developers who understand network technologies. In October 2023 i reported to mikrotik problem that VPN4 packets from MPLS interface to VRF marked in firewall as p...

uCZBpmK6pwoZg7LR

- There are no known problems with VPNv4 and route reflectors. There is a known/not yet fixed problem with VPLS and route reflectors.

What about silent firewall ignore on CPE for traffic which came from VPN4 to VRF (SUP-141699) ?

uCZBpmK6pwoZg7LR

1- v7.14 is still in beta
2- I'm having a similar problem with static routes in VRFs: viewtopic.php?t=202612&start=300#p1051523

try to use ipaddress%inface@table

uCZBpmK6pwoZg7LR

ROS 7.14 very nice. Now firewall for VPRN traffic to VRF on CPE mikrotik routers just completely and silently ignored . DNAT to VRF also don`t work.
Well done.

uCZBpmK6pwoZg7LR

Care to share how much MPLS traffic you have at peak and is it in tile arch?, we have a pilot MPLS implementation base on v6 (mpls atom/pseudowire) in one of our PoP and just running < 500mb at peak In excess of 20Gbit worth of L3VPN traffic per CCR1072 router. How you got it ? I cannot pass 1gb/s ...

uCZBpmK6pwoZg7LR

Tell me please, what are the advantages of a "exposed lo" interface over the old way?

I seen mention that it potentially can fix issue with MPLS VPN4 security firewall bug.

uCZBpmK6pwoZg7LR

Is this ChatGPT? What the hell are you talking about? An ISP should never put any kind of data plane firewall in an MPLS core. MPLS core P and PE routers only have firewall rules for the control plane of the P and PE routers. What dumb approach is this? CE devices should have localised firewall as ...

uCZBpmK6pwoZg7LR

Don`t use MPLS VPN4 ROS 7 because you CPE will be completely open for remote side of tunnel. Firewall fail to detect inbound interface and mark it as unknown and if you filter something using : add action=drop chain=input in-interface=<mpls interface> traffic will reach you CPE without any limitatio...

uCZBpmK6pwoZg7LR

I lost any hopes that MPLS related bugs in ROS 7 will be fixed. Started to look for another router brand without success for now.

uCZBpmK6pwoZg7LR

Please fix SUP-130540 and SUP-130672

uCZBpmK6pwoZg7LR

Fix at last firewall problem with interface unknown to interface unknown. Due to this issue mikrotik firewall does not work at all for MPLS VPN4 traffic. You have critical security issue but continue to fix useless docker containers.

uCZBpmK6pwoZg7LR

Please fix bug SUP-125227 and SUP-129944 (traffic from interface unknown to interface unknown) . It is not possible to use firewall due to it.

uCZBpmK6pwoZg7LR

Good day/morning/night. I have most probably quite weird question. Do exist some kind of limitation in mikrotik about amount active unique VPN4 tunnels in network. I have a tiny mpls based network where i have quite a lot of VPN4 tunnels and i cannot pass more than 200 active unique VPN4 tunnels. Wh...

uCZBpmK6pwoZg7LR

any plans to fix interface unknown in firewall for mpls vpn4 traffic ?

uCZBpmK6pwoZg7LR

1) make routing mark at mangle prerouting for public WAN port 1.1.1.1:tcp/22
2) dnat using routing mark 1.1.1.1:tcp/22 -> 10.255.255.254:22

uCZBpmK6pwoZg7LR

I just wanted to post a quick update. It appears the upgrading to 7.10 fixed the VPNv4 issues we had.

Nope not everything fixed. Traffic to bridge interface which is member of VRF still don`t hit mangle prerouting and also not possible to ping it from another side of tunnel.

uCZBpmK6pwoZg7LR

any chance to fix MPLS packets which does not follow packet flow diagram in case if destination ip is interface ip address member of VRF ( ie input interface unknown isue)?

Added quoted text. Nobody reported the bug to MikroTik before May 10th.

We are working of BFD support.
From brief look over reported BGP issues in the this topic, they should be polished and fixed in 7.9.

I'd love to see VTI implemented on RouterOS, but I kinda lost hope. I'd even gladly swap Wireguard for VTI.
