Hi,

Currently as part of VPP compilation, there are commands such as "make 
install-dep" and "make install-ext-deps" which downloads required dependent 
packages from internet. We want to automate the VPP compilation in offline mode 
i.e. our environment will not have internet access and we want to compile VPP 
in such an environment. Since the above mentioned commands by default reach out 
to internet for downloading the required packages, how can we have an offline 
setup for VPP compilation?  

Thanks and Regards,

[vpp-dev] srv6 control plane

[Christopher Adigun]

Hi,

Please I will like to know if anyone has a way implementing srv6 control
plane just like the way Linux Control plane plugin works.

An example will be syncing srv6 entries that are advertised via BGP
(FRR,gobgp,exabgp etc) to the vpp dataplane.

Thanks

Re: [vpp-dev] veth alternative in VPP

[Neale Ranns]

I’d suggest a pipe, each end can be in a different VRF. See 
src/scripts/vnet/ipsec for a config example.

You can use loopback or pipe interfaces for this.

Re: [vpp-dev] Slow VPP performance vs. DPDK l2fwd / l3wfd

[Matthew Smith via lists.fd.io]

Did you see my other suggestion about increasing buffers-per-numa? Your
NICs were missing some RX's because no buffers were available.

Setting the main heap page size to use either 2M or 1G hugepages instead of
using default 4k pages will probably help too.

[vpp-dev] veth alternative in VPP

[Mahdi Varasteh]

Hi,
I am looking for veth pair alternative in VPP. I want to pass traffics between 
two VRFs and I want them to be processed as input packets to an interface( to 
use NAT or other ip features), so route leakage is not gonna help. Also, since 
I'm using one instance of VPP with multiple VRFs, using memifs are not viable.
Are there any methods in VPP to achieve the same goal?

Regards.

Re: [vpp-dev] Support for VPP compilation in offline mode

[Zhang, Fan]

Hi Chinmaya,

In VPP's Makefile (vpp/Makefile at master · FDio/vpp · GitHub 
) line 65 to 182 
contains the necessary packages to be installed for compiling vpp 
(depends on your OS). You may  install these packages on your host 
manually before compiling VPP.


Regards,

Fan
