Hi!
A small feature request: please allow us to adjust MTU for veth interfaces that are used for containers. Both upwards (for jumbo frames) and downwards.
Up.
Also, is there a more official forum for feature requests? I don’t want to submit a service ticket just for a wishlist item.
If you go to help.mikrotik.com, there is a category for feature requests. Stuff like adding a setting like MTU on VETH seems like a fair request.
I just noticed. I guess container development on routers is a recent thing. Using a mtu 1500 in an environment that should be similar to a loopback is not what I expected.
I don’t know if this was added in later versions of RouterOS or not, but as an FYI I was able to set MTU of a VETH interface after adding it by doing this:
/interface/set mtu=1320 [find where name=veth5]
This was on 7.15.3 where you cannot set it with webfig or winbox.
Thanks, @maple .
TWIMC, the above setting persists between reboots but is not shown in /export on 7.21. You can only see value in /interface print once container is started and the other side of veth is up. This value is the host side MTU. The value inside container stays 1500 (to change do /container shell test cmd="ip link set veth-test mtu 9000" no-sh).
