Hi,
I've had success with the iproute2 manpage example for encapsulating
outgoing traffic in MPLS, but I've not found a way to add decap routes
inbound.
I've tried "ip route -f mpls add 100 dev lo" and other variations, but I
get netlink errors back.
Has this been built yet? Is there sample config that I can try out? I'm
running a home-built 4.3 kernel + iproute2 built from head (on ubuntu
15.10) and am comfortable with perf and splashing around in the codebase if
need be.
Hi Sam,
This certainly works on net-next, albeit with a bug on the subsequent
"ip route -f mpls list" that I'll shortly be sending a patch for.
Have you first set an appropriate label table size? E.g.:
$ sysctl net.mpls.platform_labels=1048575
If you intend to receive non-BOS traffic over your route above, then you
should also make sure to enable mpls input on lo (and your actual input
interfaces), otherwise the traffic will be dropped.
Thanks,
Rob
