[mpls-linux-general] cannot configure nhlfe

[Dylan S. <sy...@ho...>]

Hi

I have been trying to set up LSPs between two computers running mpls-enabled 
kernels (FC2).  I am able to compile the patched kernel source code OK, boot 
into the new kernel and I run the following commands:

# mpls nhlfe add key 0
# mpls nhlfe change key 0x2 instructions push gen 32 nexthop eth0 ipv4 
192.168.1.1

The second of these commands returns:

RTNETLINK answers: Operation not permitted.

The arguments in the command line are consistent with my network setup, and 
all the other basic instructions (eg. ip route add, mpls labelspace, mpls 
ilm add)  all work as expected.

Can you help?

cheers
