The following command does not work:
$ ip route add 10.201.0.0/24 nexthop encap mpls 300 via 10.200.0.1 dev ntfp2
Error: "nexthop" or end of line is expected instead of "encap"
In fact, iproute2 version points to v4.3.0, but the xenial kernel is a 4.4.
$ ip -V
ip utility, iproute2-ss151103
=>
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/commit/?id=6720eceff7b4
With an iproute2 v4.4.0 (iproute2-ss160111), that command works:
$ modprobe mpls_iptunnel
$ ./ip/ip route add 10.201.0.0/24 nexthop encap mpls 300 via 10.200.0.1 dev ntfp2
$ ./ip/ip r
[snip]
10.201.0.0/24 encap mpls 300 via 10.200.0.1 dev ntfp2
At least, this patch is missing:
1e5293056a02 ("lwtunnel: Add encapsulation support to ip route")
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/commit/?id=1e5293056a02
** Affects: iproute2 (Ubuntu)
Importance: Undecided
Status: Incomplete
