interfaces-vrf(5)
# NAME
*interfaces-vrf* - VRF extensions for the interfaces(5) file format
# DESCRIPTION
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.
# VRF-RELATED 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
```
