Hi Mauricio,
CC'ing Shwetha, she implemented the IOAM plugin. Last time I checked, IOAM
namespaces were not included, so it is probably based on the -03 version of
draft-ietf-ippm-ioam-data. Actually, just to let you know, there is already
someone that is going to rebase the implementation on t

The introduction of IOAM namespaces was the big addition and came with version
4 of the draft. Since then, some other (small) modifications were also added
here and there.
Last time I talked to Shwetha during IETF, she told me it was planned to update
vpp/ioam to a more recent version of

I did, however this is not an option as I'd like to keep my "entire topology
running on the same machine" philosophy.
Also, I think this could be a plus for the router plug

Guys,
Any plan to use memif interfaces for router plugin ? Also, is there a plan to
implement a multi-instance mode ? Because, for now, "enable tap-inject" only
works for one router, and not others, when I run multiples VPP instances on a
same machine.
Thanks,

My bad, I didn't thought about looking at the python code of the "connect"
method.
Thanks a million !

Hi guys,
How can I "connect" to a specific instance of VPP through the python API ?
Each instance (together, they form a topology) is run as follow:
sudo vpp unix { log /tmp/vpp1.log cli-listen /run/vpp/cli-vpp1.sock }
api-segment { prefix vpp1 } plugins { plugin dpdk_plugin.so { disable } }
Ping Dave, as I'm sure he knows what could help here.

After having developed a new plugin, I'm now implementing its API in order to

After hours of debugging, I figured it out. One of our plugin unformat function

command. Indeed, "exec" reads each line of the parsed file and put them next to
each other in the (input) buffer. That's why it was sil
Hi everyone,
Just noticed that my file was not executed with "vppctl exec ". Actually,
it *is* executed, as long as a line doesn't contain a command for my plugin. Is
"exec" only for some vpp "core" commands, such as "set" ? I already tried the
alternative solution by calling "vppctl " for each

Oh and by the way, when I say "Pings work" I mean "pings on vpp interfaces" and
that's the only way I can see packets in VPP (which is normal after all). But
still, pings to 10.10.2.2 work but no trace in VPP (same as iperf packets).
Just wanted to clarify this, because it was a bit unclear.

My node is located right before ip4_lookup. What's the fastest/cleanest way to

Hey guys,
In buffer_node.h, there are the following macros:
- vlib_validate_buffer_enqueue_x1
- vlib_validate_buffer_enqueue_x2
- vlib_validate_buffer_enqueue_x4
In a node, I was just wondering what was the use idea behind that ? Is it for a
reason of speed ? I mean, you're obviously faster if y
n, which is actually what is executed with the now-deprecated install.sh.
What should I do ?

Here are two issues I faced while installing/running VPP. It would be great to
fix them.
1) Install not executed (at least, it seems that it's the case...) - tested
with current version 18.01 (cloned today) but it's the same with previous
versions too.
