Hi Everyone , i have apu board from pc-engines running 1.4 latest. My config is as basic as i can make it , i assign 192.168.1.1 to eth0 , and 192.168.1.3 to eth2 , commit and save , When i ping these ips , i get the same arp and i can ever remove the eth2 cable, and pinging never faults. Any idea ?

  root@vyos:/proc# show configuration 
interfaces {
    ethernet eth0 {
        address 192.168.1.1/24
        hw-id 00:0d:b9:37:10:4c
    }
    ethernet eth1 {
        hw-id 00:0d:b9:37:10:4d
    }
    ethernet eth2 {

arp output

? (192.168.1.1) at 0:d:b9:37:10:4c on en0 ifscope [ethernet]
? (192.168.1.3) at 0:d:b9:37:10:4c on en0 ifscope [ethernet]

Try it:

sudo sysctl -w net.ipv4.conf.all.arp_announce=1
sudo sysctl -w net.ipv4.conf.all.arp_ignore=2

Set those options , and it still acts strange …if i have eth2 plugged in , clear my arp table , i get the correct mac

when i plugin in eth0 , the arp changes for eth2 to the same arp as eth0

Perhaps you need bonding?
It there any reason to set the same network on 2 different interfaces ?
