Hi there,
So I am currently running vyos 1.2.1 - and are currently getting into a little bit of trouble with our IX (SIX in seattle). It seems some packets are originating from our vyos router with a null mac (mac of 00:00:00:00:00:00)
Just curious if this has been seen before; if there is a known workaround; if this is a bug upstream… any ideas how to fix this would be appreciated.
vyos should not craft any packets with 00:00:00:00:00:00 as src or dst, do you see these packets on a local tcpdudmp? could you also capture a pcap with the packet in? i’ve been monitoring my systems now, but cant see the issue here.
This might be a driver issue or a configuration issue, could you provide the output of the command ip link
thanks for your help @runar
I dont have a capture personally - although the SIX is sending me emails whenever they capture one The interface in question is eth3. Ill run a capture today to see if I can get one (I did try last night with no success).
