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
