Trying to figure out how one can use iproute2 to manage static label-switched MPLS routes in Linux kernel 4.1. I am aware iproute2 support for MPLS might be incomplete right now [2]. Can anyone please shed some light on what iproute2-4.1.1 is currently able to do? This is what I have found so far: Documentation/networking/mpls-sysctl.txt ---------------------------------------- /proc/sys/net/mpls/platform_labels /proc/sys/net/mpls/conf/<interface>/input Load mpls module ---------------- sudo modprobe mpls_router Find sysctl support ------------------- sysctl -a --pattern mpls net.mpls.conf.eth0.input = 0 net.mpls.conf.eth1.input = 0 net.mpls.conf.lo.input = 0 net.mpls.platform_labels = 0 Enable mpls support ------------------- sudo sysctl -w net.mpls.conf.eth0.input=1 sudo sysctl -w net.mpls.conf.eth1.input=1 sudo sysctl -w net.mpls.platform_labels=1000 push??? (how to add prefix-to-push action?) ---- sudo ip route add 1.1.1.1/32 via mpls 100/200/300 dev eth0 swap??? (how to add label-swap action?)
Hi Everton Marques, I tried above command for push operation- sudo ip route add 1.1.1.1/32 via mpls 100 dev eth0 After this when I ping to 1.1.1.1, ping was successful, but ping packet is normal IP packet there is no mpls header encoded with ping packet with label 100. Did you find the solution ? Thanks in advance. Best Regards, Abhishek
