TRex based on DPDK, have high performance for traffics generator scenario. TRex has two deployment scenarios, one is Stateless mode, another is Server/client mode. How different for them? As follow pic. Btw, TRex has a GUI tool that can easy config traffic pattern, but that only support in Stateless mode. For Server/Client mode, only CLI (you can reference “Linux SRv6实战 （第三篇） 多云环境下Overlay(VPP) 和Underlay整合测试 ” that use Server/Client mode). For the article, only focus on stateless mode and GUI tool.

My VPS(Bandwagon) include OpenVPN script, but only support Centos6.x that version not good for docker (my blog deploy by docker Blog顺利完成搬家之Bandwagonhost VPS), so need to do by other scripts. OpenWRT config OpenVPN client has some different, so summary the info to the article for review.

But due to GFW, OpenVPN couldn’t establish at last, reset happened between server and client, but the setup should workable.

Deploy OpenVPN at Server

Don’t know why couldn’t find OpenVPN pacakage by yum, even if have epel source

[root@frank ~]# rpm -qa |grep epel
epel-release-7-11.noarch
[root@frank ~]# yum install openvpn
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirrors.usc.edu
 * extras: repos.lax.quadranet.com
 * updates: mirror.fileplanet.com
No package openvpn available.
Error: Nothing to do

Config call-home that active smart license

xrv9k should have some default call-home, in some scenario, need to add some extra configuration, as follow:

domain name cisco.com
domain name-server x.x.x.x  >>> dns server
call-home
 service active
 contact smart-licensing
 http-proxy y.y.y.y port 80  >>> proxy server
 profile CiscoTAC-1
  active
  destination transport-method http
 !
!

Add crypto config
