Ok, with exp2tc I can create a MPLS command like this: var_default=`mpls nhlfe add key 0 instructions exp2tc 0x3 0x1 push gen 600 nexthop ath1 ipv4 10.0.6.4|grep key| cut -c 17-26` mpls xc add ilm_label gen 500 ilm_labelspace 0 nhlfe_key $var_default But, if I have multiple EXPs to be mapped, for instance 0x3, 0x6 and 0x0 have I got to do like in LER E1, where I created 3 mpls entries and then I mapped them with iptables specifying the target with "-j" option? (iptables -t mangle -A FORWARD -s 172.16.30.0/24 -m dscp --dscp 0x06 -j mpls --nhlfe $key_1) this way I'm still reading Layer 3 information...right? Or I can do something like this? var_default=`mpls nhlfe add key 0 instructions exp2tc 0x3 0x1 exp2tc 0x6 0x2 exp2tc 0x0 0x3 push gen 600 nexthop ath1 ipv4 10.0.6.4|grep key| cut -c 17-26` Thanks a lot, you're very helpful!

Ok, I think I've done it, thank you. Another thing, can I map directly different labels on TCs, without using exp bits? What I mean is, if I have one flow which arrives with label 300 and another one with 500, can I schedule them differently without writing EXP field?

Hello Luca, I don't know if you can - look if the mpls command has a switch - something like --set-tcindex; if it does, you can, otherwise I don't know if you can...
