If you want to take it to the next level, and do a great service to your
fellow man, I would encourage you to update the tutorial to use:

https://docs.fd.io/vpp/17.10/clicmd_src_plugins_memif.html

to interconnect the various vpp instances :)

[Justin Iurman]

Florin,

Thanks for that. What's the difference between my technique and yours using 
telnet ? Also, what does the 0 correspond to ? Is it an instance index or 
something else ?

[Florin Coras]

Justin, 

That looks about right. The other option would be to use telnet. So instead of 
“cli-listen /run/vpp/cli.vpp1.sock” do something like “cli-listen 
localhost:5002” and then telnet 0 5002

Re: [vpp-dev] Running multiple instances of VPP as it was allowed with VPP-lite

[Justin Iurman]

Hi Florin,

In fact, that's what I was already trying. Anyway, I found a way to make it 
work but I'm still not sure that's the right/best way to do so.

# vpp1 instance
sudo vpp unix { log /tmp/vpp1.log full-coredump cli-listen 
/run/vpp/cli.vpp1.sock } api-segment { prefix vpp1 } api-trace { on } plugins { 
plugin dpdk_plugin.so { disable } }

# vpp2 instance
sudo vpp unix { log /tmp/vpp2.log full-coredump cli-listen 
/run/vpp/cli.vpp2.sock } api-segment { prefix vpp2 } api-trace { on } plugins { 
plugin dpdk_plugin.so { disable } }

# vppctl vpp1
sudo vppctl -s /run/vpp/cli.vpp1.sock 

# vppctl vpp2
sudo vppctl -s /run/vpp/cli.vpp2.sock 

Since I build a dynamic topology, I won't use startup config files. That's why 
i'm using parameters in command line. Commands above work good, as it mimics 
the behavior I had with VPP-lite. But again, is it the right/best way to do so 
? Or would there be anything better suited ?

[vpp-dev] Running multiple instances of VPP as it was allowed with VPP-lite

[Justin Iurman]

Hi all,

Is it still possible to run multiple instances of VPP, just like it was done 
with VPP-lite (see here: https://wiki.fd.io/view/VPP/Progressive_VPP_Tutorial) 
before merging it ?

Actually, my problem is the following. I need to run several instances of VPP 
(eg. vpp1, vpp2, vpp3, etc) to simulate a topology. But, for some reason, I'm 
not able to make it work as expected. I've already disabled DPDK plugin to run 
in "lite" mode. Could it be a configuration issue ? VPP startup.conf:

unix {
  nodaemon
  log /tmp/vpp.log
  full-coredump
  cli-listen /run/vpp/cli.sock
  gid vpp
}

api-trace {
  on
}

api-segment {
  gid vpp
}

plugins {
  plugin dpdk_plugin.so { disable }
}

I tried to compare both VPP and VPP-lite. A first observation showed that VPP 
is installed as a service, which is not the case for VPP-lite. I've also 
compared both config files. Here is VPP-lite startup.conf:

unix {
  nodaemon
  log /tmp/vpp.log
  full-coredump
}

api-trace {
  on
}

api-segment {
  gid vpp
}

Currently, here is how I try to mimic VPP-lite behavior with VPP:

sudo vpp api-segment { prefix vpp1 } unix { cli-listen /run/vpp/cli.vpp1.sock }
sudo vppctl -s /run/vpp/cli.vpp1.sock

It works for one instance, but not for more, even if it does not throw any 
error. Do you have any idea on how to proceed or what is wrong here ?

Thanks !

Justin
