Hi Folks,

After kernel update from 4.9.6 to 4.9.8, I get the below error
message when I run this command:

root@Typhoon:~# ip route add default table 210 nexthop dev eth0 via 10.68.64.1 
weight 1 nexthop dev eth0 via 10.68.64.2 weight 1
RTNETLINK answers: Operation not supported
root@Typhoon:~# uname -a
Linux Typhoon 4.9.8 #1 SMP Tue Feb 7 17:14:54 CET 2017 x86_64 Intel(R) Core
(TM) i5-2520M CPU @ 2.50GHz GenuineIntel GNU/Linux

Is this the expected behaviour?

Any response are welcome
TIA

Marco
