[mpls-linux-general] Problem setting MPLS tunnel with iproute2 in mpls-linux

[Steve M. <emu...@gm...>]

Hi List

I am testing mpls-linux in a voyage linux system and I am suffering a weir
behaviour.

I am following several tutorial for set up the mpls tunnels and I am
stucked when I need to map the IP traffic to an specific MPLS tunnel. I one
node, I am doing this:

mpls nhlfe add key 0 instructions push gen 1000 nexthop eth1 ipv4
10.10.10.22

and then

ip route add 10.10.0.2/24 via 10.10.10.22 mpls 0x2

but the ip route command gives me an error:

Error: argument "mpls" is wrong: Can't define mpls when using IP forwarding

But I am sure that IP forwarding is disabled:

# sysctl net.ipv4.ip_forwardnet.ipv4.ip_forward = 0

So, how can I fix it? This is a normal behaviour and there is another way
to stablish the tunnel? Or maybe the iproute package I am using is not the
right one?

My mpls compiled version is: Linux voyage 2.6.32
And iproute2 package is get from:

https://github.com/i-maravic/iproute2

Any idea or suggestion?

Thank you

Kind regards,
Esteban
