-.. cfgcmd:: set interfaces {{ var0 }} <interface> xdp
-
- Enable support for Linux :abbr:`XDP (eXpress Data Path)` on recent 1.3 rolling
- releases. You must enable it for every interface which should participate in
- the XDP forwarding.
-
- XDP is an eBPF based high performance data path merged in the Linux kernel
- since version 4.8. The idea behind XDP is to add an early hook in the RX path
- of the kernel, and let a user supplied eBPF program decide the fate of the
- packet. The hook is placed in the NIC driver just after the interrupt
- processing, and before any memory allocation needed by the network stack
- itself, because memory allocation can be an expensive operation.
-
- .. warning:: This is highly experimental!
-
- .. note:: Enabling this feature will break any form of NAT or Firewalling on
- this interface, as XDP is handled way earlier in the driver then iptables/
- nftables.
-
- Enabling this feature will only load the XDP router code as described here:
- https://blog.apnic.net/2020/04/30/how-to-build-an-xdp-based-bgp-peering-router/
-
- Example:
-
- .. code-block:: none
-
- set interfaces {{ var0 }} {{ var1 }} xdp \ No newline at end of file
