Another good example is vxlan.
Not sure what will happen if multiple graph nodes are fighting for the
same port though.

Are you implementing a new graph node, which consumes UDP traffic? If so, then
the BFD example is a way to redirect interesting traffic to your new node...

Hi Klement,
I want to redirect data to a new udp port. Do I need to modify VPP
code?
Adding a new UDP_DST_PORT_xxxx enum types??
Thanks a lot!!!

Hi Lin Huang,
You can take a look at bfd_udp_init() in bfd_udp.c to see how the BFD
feature registers to listen on BFD ports using udp_register_dst_port().
Thanks,
Klement

Hi, all.
I want to know how to redirect specific UDP port data to a
new
node?
Dose udp_register_dst_port make effecet? Or using the arc with feature?
Thanks!!!
