iproute2 mpls support

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

 

No, sorry.
