Public bug reported:
The problem seems to incriminate systemd-networkd (v229-4ubuntu21.1), not the
network/bonding configuration.
When a full bonding configuration is made with systemd in /etc/systemd/network,
on 2 two differents physical hosts, same hardware and in same VLAN:
----- bond0.netdev ------
[NetDev]
Name=bond0
Kind=bond
[Bond]
Mode=802.3ad
TransmitHashPolicy=layer3+4
MIIMonitorSec=100ms
LACPTransmitRate=fast
----- vlan3147.netdev ------
[NetDev]
Name=vlan3147
Kind=vlan
[VLAN]
Id=3147
----- bond0.network ------
[Match]
Name=bond0
[Network]
VLAN=vlan3147
BindCarrier=enp1s0f1 enp1s0f0
LinkLocalAddressing=no
----- enp1s0f0.network ------
[Match]
Name=enp1s0f0
[Network]
Bond=bond0
----- enp1s0f1.network ------
[Match]
Name=enp1s0f1
[Network]
Bond=bond0
----- vlan3147.network ------
[Match]
Name=vlan3147
[Address]
Address=**masked ip***/25
[Route]
Destination=10.0.0.0/8
Gateway=**masked ip***
[Route]
Destination=**masked ip***/16
Gateway=**masked ip***
And in /etc/modprobe.d/bonding.conf
options bonding max_bonds=0
..... the two different physicals hosts have the same MAC address on
bonding:
on host A:
32: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UP mode DEFAULT group default qlen 1000
link/ether 16:d6:b0:24:16:3b brd ff:ff:ff:ff:ff:ff
on host B:
32: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue
state UP mode DEFAULT group default qlen 1000
link/ether 16:d6:b0:24:16:3b brd ff:ff:ff:ff:ff:ff
So strange... how the MAC is generated ? There is no relevant rules in
/etc/udev/rules.d/70-persistent-net.rules to explain it, and issue occurs only
with systemd-network, *NOT* with legacy configuration /etc/network/interfaces.
