Re: [mpls-linux-general] mpls linux

[Adrian P. <adr...@gm...>]

Please, post your replies to the list, so other can help you.

Could you try to run the mpls command with strace? Something like strace
mpls nhlfe add key 0 instructions push gen 1000 nexthop eth1 ipv4 10.10.0.3

... and post the output to that.

Cheers,
Adrian
