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
