Interface Ethernet Issue

[zakwan]

Hi,

I was moving one interface ip from old VM to new VM and then I turn-off old VM. At first it was working, I can ping the connected ip to this interface. But after I turned off the old VM, I suddenly can’t ping the ip connected to this interface anymore. When I tcpdump I can’t see the ICMP goes to this interface but instead it goes to default route.

I able to ping the IP by using command “ping 10.255.2.6 interface eth1”, then it can go to this interface correctly. Why it can’t go thorough this interface using the connected route table?

vyos:~$ show ip ro 10.255.2.6
Routing entry for 10.255.2.4/30
  Known via "connected", distance 0, metric 0, best
  Last update 00:09:07 ago
  * directly connected, eth1```

I found this error :-

eth2: can’t get flags: No such device

There is not eth2 in my router. Maybe mac-address was change?

If you have bound the hw using hw-id then yea, that will be the problem. You don’t show your config so it’s hard to know.

Yes I believe its a hw-id issue. Maybe it was conflict with the old router. Its okay I will later plan to reboot this machine. Thank you
