$ setup.sh  --machine intel-x86-64 --dl-layers --distro wrlinux
$ . ./environment-setup-x86_64-wrlinuxsdk-linux
$ . ./oe-init-build-env
$ bitbake wrlinux-image-glibc-std

If boot from harddisk and there is ip=dhcp in kernel cmdline:
$ cat /proc/cmdline
console=ttyS0,115200 root=/dev/sda1 rw ip=dhcp 

There will be many strange routes:
$ route
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         _gateway        0.0.0.0         UG    100    0        0 eth0
default         _gateway        0.0.0.0         UG    1024   0        0 eth0

10.24.16.0   0.0.0.0         255.255.255.0   U     100    0        0 eth0
_gateway        0.0.0.0         255.255.255.255 UH    1024   0        0 eth0
foo.example.com    _gateway        255.255.255.255 UGH   1024   0        0 eth0
10.11.10.30   _gateway        255.255.255.255 UGH   1024   0        0 eth0

There are 3 workarounds:

1. Remove ip=dhcp from kernel cmdline if boot from harddisk.

2. Disable systemd-network-generator
$ systemctl disable systemd-network-generator.service
$ reboot

3. Disable systemd-networkd
$ systemctl disable systemd-networkd
$ reboot

Because we use dhcpcd (on std image) or NetworkManager (on XFCE image) to configure the network interface. So stopping systemd-networkd has no effect on the system.

Steps to Reproduce

1) setup.sh

 /lpg-build/cdc/fast_prod/WRLINUX_CI/RC_GIT/wrlinux-10/setup.sh  --machine intel-x86-64 --dl-layers --distro wrlinux --templates feature/xfce feature/dhcp-server-kea feature/ipv6 feature/kubernetes feature/netplan feature/nfsd feature/nftables feature/ntp feature/package-management feature/sftp-server feature/wireguard --layers meta-filesystems meta-security-compliance meta-virtualization --dl-layers
2). ./environment-setup-x86_64-wrlinuxsdk-linux

3) . ./oe-init-build-env

4) vim conf/local.conf

IMAGE_INSTALL:append = " systemd
5) bitbake wrlinux-image-glibc-std

6)boot the target and run commands per problem description
