vxlan2-dkms

vxlan2 is a patched version of the vxlan module in the Linux kernel that allows IP fragmentation of packets encapsulated in VXLAN.

Installation

https://github.com/cuteip/vxlan2-dkms/releases

sudo apt install dkms -y

VXLAN2_DKMS_VERSION=0.7
wget https://github.com/cuteip/vxlan2-dkms/releases/download/v${VXLAN2_DKMS_VERSION}/vxlan2-dkms_${VXLAN2_DKMS_VERSION}_all.deb
sudo apt install -y ./vxlan2-dkms_${VXLAN2_DKMS_VERSION}_all.deb

Limitations

• Supported Linux Kernel versions: 6.1 - 6.5
• Supports only IPv6 underlying network
  • It's likely that applying a similar patch would make the underlying network work with IPv4 as well.
• The upstream vxlan module will be blacklisted when installing vxlan2-dkms
