Unable to route on my local breakout 7.1beta2

Hello,

I'm having issues with routerOS 7 beta. It was working fine for a few weeks but a reboot of the router seems to have broken something. This also happened to other hardware and I just swapped the hardware and it was working again, until now.

RouterOS: 7.1beta2
model: 750GL
firmware-type: ar7240
current-firmware: 7.1beta2

I can connect to the router on a L2 basis (mac connect). But I'm unable to ping it or route over it even though I receive dhcp from the device.

Ip & Route on laptop:
Code: Select all
$ ip route
default via 192.168.33.1 dev enp0s25 proto dhcp metric 20100 
192.168.33.0/28 dev enp0s25 proto kernel scope link src 192.168.33.9 metric 100

$ ip a

I'm not sure why the device is doing this.

Re: Unable to route on my local breakout 7.1beta2

I'm having the same issue with my Chateau:

Everything was working fine for a day after upgrading to 7.1beta2 (from the chateau default 7.0beta6), but after some ssh issues (same as this thread), I rebooted the Chateau and it refuses to route since.

My PC is connected to a hap ac (with stable firmware), which is connected to the lan-bridge of the Chateau. After putting the Chateau on the same bridge with the PC, everything was working. Directly connecting my PC to the chateau was working too.
But routing via the hap ac to the Chateau is not working.

As a workaround I downgraded to 7.0beta8 for now and everything is fine, except the SSH issue.

A temporary workaround this issue is to disable the primary route after boot and then re-enable it.

I found this fixes it for me, until the next boot of course.

This doesn't seem to work. Routing to the internet is not the issue, routing to the gateway itself is atm the issue, that is the connected route.

You did put me on the right track, disabling & enabling the ip address on the VLAN interface actually fixed it.

Anyone knows if beta3 solves this? The changelogs are useless...

Just had this happen to me on 7.1rc7 so its still there. Disabled and enabled interface and its back. Was adding a new interface to a running router.

Hey, I had the same problem with 7.2.3.

IPv6 traffic was not going out at all despite the fact that _all_ the configuration was _okay_.

When I would ping something using ping in mikrotik, It would return 22(invalid argument) errors.

Disabling and re-enabling the wireguard interface fixed the problem.

Same @ v7.3beta40

Get 22 (Invalid argument) when ping to target under VLAN. Target under that can't ping gateway(ros) ip, network complete break.

Could ping "nomally" when "Interface" specfic in winbox ping tools.

( It's in same layer-2, connected route, it shoud ping even without interface specfied , right? ).

Solve by disable & re enable the ipv4 on that ros interface. Everything works fine, network recover, no need to specfic inteface for ping. (until next time?)

STRANGE.

thank you for pointing this out - in fact still on v7.13.3 - disabling and re-enabling the IP on the vrf bound interface that reports the "invalid argument" fixes the situation.

Hi, I see you posted this today also, we are currently on 7.12.1, we seem to only ever has this issue on bridges that have just physical ports added to them, bridges with vlan interfaces added to them seem fine. Have you noticed this also?

I also figured out before hand disabling/enabling the IP as you say on the interface works/fixes it. But it happens everytime our CCR has a power cut. It's a CCR2004, what model do you have?

Lastly is your interface/bridge experiencing the problem in the a vrf or just in main?

Just trying to get to the bottom of this to see if it's a firmware/software bug mikrotik need to fix or a config error etc.
