Hello,
we have 2x QFX10002-36Q running JunOS 20.2R2-S3.5 and some /29 and /28 prefixes that don't want to lose ip addresses due to VRRP(virtual-gateway). So we tried the method with same mac address on both devices in the irb described
here.
Routing worked as expected, but both devices had a lot of log spam:
"KERN_ARP_DUPLICATE_ADDR: duplicate IP address x.x.x.1! sent from address: 40:de:ad:60:00:05 (error count = 36092)"
Config on both devices:
unit 7 {
description voice;
family inet {
address 1.2.3.1/27;
}
mac 40:de:ad:60:00:05;
}
vlans {
voice {
vlan-id 7;
l3-interface irb.7;
}
}
I could not find another solution without losing two IP addresses per prefix in addition to the gateway IP itself. Maybe there is another solution?
Thank you for helping before hand!
kind regards
