we have centos 6 64 bits .
lernet l compiled kernel 4.9.7 with (vrf lite) as module .



[root@server iproute2-4.20.0]# uname -a
Linux server.domain.local 4.9.7 #1 SMP Mon Jan 14 04:20:52 CST 2019 x86_64 x86_64 x86_64 GNU/Linux

[root@server iproute2-4.20.0]#


The problem is seems that VRF commands is not being accepted , not sure whats missing still to get VRF feature on centos .

i have a scenario where i have multiple lans must be having same subnets and need them isolated form others .


CHECK Error Below :

[root@server iproute2-4.20.0]# ip link add vrf-blue type vrf table 10

can you find a way to let the command below work ?

ip link add vrf-blue type vrf table 10


I tried to search much but not luck !

Thanks in advance !

Please use [code] tags to post output...and note that the color you chose for the error message made it unreadable

For ip link help, I see
Nowhere in the help output do I find the word table...what, exactly, are you trying to accomplish?

the vrf commands is not getting to work even though i compiled the kernel with VRF lite as module


i just need to have the vrf commands work !

Hi,Dr.x:

I also encountered this problem now, Did you fix the problem? If you did,please tell me how, thanks.
