Introduction
Now BU had integrated BNG feature to XRv9000 platform in new version (from 631), that can let customer integrade the feature in their NFVI Infrastructure, that will flexible deploy the BNG in same Server Box. And the article will set up a simple vBNG environment that build by VIRL + XRv9000, and simple test IPoE/PPPoE. That environment will help you to easy TS vBNG PI issue, and packets paths.
Platform
I am not use openstack, only use VIRL that easy to deploy Demo/Poc. If you have openstack, I suppose you need to design network and boot server and client by Ubuntu/Centos ISO, that will mostly like customer real network, and you can refer Roy's doc that build by openstack:
Cisco vBNG on ESXi Quick start - IOS XRv 9000 Router based vBNG lab guide
Linux
Due to VIRL integrate linux server is Ubuntu, so you need to know how to do basic operation on Ubuntu platform.
XRv9k
BNG packaging on XRV9K is enabled only on full & fullk9 .ISO/OVA, support from 631, I use the 641 37I. You can download the image from follow path in people server:
/auto/prod_weekly_archive1/ # -> SIT Version
/auto/release.IOX/bin/ # -> official release Version
limitation for vBNG - not include all, you can check 641 NPI for detail info
- Not support VRF
- Not support bba-group in PPPoE
- Not support RP based session, IPoE/PPPoE
- QOS have limit support

DHCP/Radius Server/Client
I had builded a customize ubuntu clould image that include dhcp and freeradius service, and you can direct to download the vmdk from follow link:
You can upload the image to VIRL, then set up topology in VIRL. And choose correct image, as follow example:
Attention: If you want to build self ubuntu cloud image, you can link server to outside by flat port in VIRL, then update source and apt-get install the software. Then create snapshot by follow, then find the image from VIRL server, then you can share to other guys~:-)
Click follow button to generate initial config in VMMaestro
You can change eth config before server boot, and add default gw, or disable eth0 by "ifconfig eth0 down"
- DHCP
- change dhcp config in "/etc/dhcp/dhcpd.conf"
- check log in "/var/log/syslog"
- enable service by "sudo dhcpd -d &"
- Radius
- stop default service first by "service freeradius stop"
- after stop, you can enable debug mode by "freeradius -X &"
- "user" and "client.conf" in this path "/etc/freeradius/"
- IPoE Client
- you can renew the dhcp address by "dhclient -nw"
- PPPoE Client
- Run "sudo pppoeconf"
- dialer by "pon dsl-provider"
- stop connection by "poff"
- check dialer log by "plog"
