[mpls-linux-general] cannot configure nhlfe

[<mar...@ti...>]

Hello,
I try to set up a LSP, so I run the following the commands:

mpls nhlfe add key 0
mpls nhlfe change key 0x2 instructions push gen 10000 nexthop eth2 ipv4 1=
98.168.12.5

but the second of these commands returns:
 
RTNETLINK answers: Operation not permitted. 

If I run the command dmesg, the output is:

MPLS DEBUG net/mpls/mpls_netlink.c:323:mpls_add_nhlfe: Enter
MPLS DEBUG net/mpls/mpls_opcode.c:345:mpls_build_opcode_push: enter
