interfaces-vrf5
Vrf extensions for the interfaces(5) file format
Overview
Linux has support for Virtual Routing and Forwarding (VRF) instances since Kernel >= 4.4. The following options allow to set up VRFs and adding configured interfaces to VRFs.
Note that in the Linux Kernel VRFs are represented as network interfaces, too. See https://www.kernel.org/doc/Documentation/networking/vrf.rst for more details.
Options
vrf-table table id
The id of the kernel routing table associated with this VRF interface. This parameter indicates that the interface where it is specified shall be a VRF.
vrf vrf interface
The vrf the interface should be assigned to. This parameter is specified on regular interfaces which should be within the given vrf.
Examples
A VRF interface:
auto vrf_external iface vrf_external vrf-table 1023
A regular interface which should be within a VRF:
auto eth0 iface eth0 address 192.2.0.42/24 address 2001:db8::42/64 gateway 192.2.0.1 gateway 2001:db::1 vrf vrf_external
