Hoi Ondrej and bird-users,

Apologies for my resend. For some reason, my mail provider had tucked away your response to my mail, which I saw only after I resent it. Thank you for the pointer - I'm happy to test this out in the lab, and once we're ready with kernel programming parts of the mpls stack, maybe I can help with the LDP parts. Of course, I also have to update the linux-cp side of VPP to consume netlink messages and program the dataplane, so it's more of a longer term feature arc for me. I am very interested to help making the combo Bird+MPLS+LDP+VPP work, though.

groet,

Pim

Hoi,

Resending to @network.cz (was @trubka.network.cz earlier). If there's any way I can retrieve the MPLS / LDP state for Bird2, I'd appreciate it.

groet,
Pim

Hoi folks,

I work on VPP (a fast userspace based dataplane implementation https://fd.io/), and helped contribute the ability for this dataplane to consume Netlink messages (github.com/pimvanpelt/lcpng)
One thing that I've been asked about quite a bit is the ability to program the VPP dataplane with MPLS forwarding. I use Bird2 in my own deployment (https://ipng.ch/s/articles/2021/09/21/vpp-7.html) and was wondering what the current thinking is for Bird to support signalling with LDP. Last I saw was:

Maria, do you have pointers on the current state of the union for an LDP implementation for Bird? I'd like to add MPLS support to Linux Control Plane (https://ipng.ch/media/virtualnog/index.html)

groet,
Pim
