I use L2. Can somebody clarify what advantage/disadvantage is there for
L2,L3,L3S?
I need also to be able to use DHCP inside the container. In a first boot I
get an IP from DHCP, and set the interface down and turn that IP into
static.
Any way, ipvlan should work as simply as the other network options.
Another question for the networking gurus, how do you represent this
configuration with netplan?
-------------------
auto lo eth0 eth1
iface lo inet loopback
allow-hotplug eth0 eth1
iface eth0 inet dhcp
iface eth1 inet static
address X.XX.X.215
netmask 255.255.255.0
mtu 1500
post-up echo "Setting up $IFACE"
post-up ip route replace default via X.XX.X .1 dev $IFACE
post-up ip rule add from X.XX.X.215 table $IFACE
post-up ip route replace default via X.XX.X .1 dev $IFACE table
$IFACE
post-up ip rule add iif $IFACE table $IFACE
post-up ip route replace default via 192.168.88.1 dev eth0
post-up ip route show table $IFACE
given
/etc/iproute2/rt_tables
1 eth0
2 eth1
The purpose is to send to eth1 only packets going X.XX.X.0, which is a
public IPs network, and anything else via eth0 192.168.88.1.
I tried to figure this scheme out with Netplan and I cannot see the light.
