Hi,

I am following the steps present in
(https://www.kernel.org/doc/Documentation/networking/vrf.txt) and
trying to create IPv4 VRF in latest Fedora 24 distribution with 4.5
Linux kernel.

[root@localhost ip]# uname -a
Linux localhost.localdomain 4.5.5-300.fc24.x86_64 #1 SMP Thu May 19
13:05:32 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I am getting operation not supported error as shown below

# ip link add vrf-blue type vrf table 10
RTNETLINK answers: Operation not supported

Is there any CONFIG option to enable VRF in Linux kernel ?

Yes, in drivers/net/Kconfig:

config NET_VRF
	tristate "Virtual Routing and Forwarding (Lite)"
	depends on IP_MULTIPLE_TABLES
	depends on NET_L3_MASTER_DEV
	depends on IPV6 || IPV6=n
	depends on IPV6_MULTIPLE_TABLES || IPV6=n
	---help---
	  This option enables the support for mapping interfaces into VRF's. The
	  support enables VRF devices.
