# 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_.
|
|
|
|

A VRF interface:
|
|
|

|
|
vrf-table 1023
|
|
```
|

|
```
|
|
auto eth0
|
|
iface eth0
|
|
address 192.2.0.42/24
|
