BNG + PWHE Untagged

[benediktsv]

Hi all

I have trunks connected to wholesale providers, providing xDSL/FTTH etc and the users are delivered to us via L2 trunks tagged.

I have still 7600 SUP720's terminating those connections and bit stuck using that platform (remote locations)

So I plan to xconnect it to the ASR9k running BNG   - tested with 5.3.3 and 6.1.2

the AC is like this

interface GigabitEthernet2/15.2000

description *** Incoming IPoE sessions ***
encapsulation dot1Q 2000
xconnect 1.1.1.1 666 pw-class EoMPLS
mtu 1510

where 1.1.1.1 is the BNG

here is the PEWE config

interface PW-Ether666
mtu 1524
mac-address 1212.9000.8666
attach generic-interface-list GI-Te0-1
l2overhead 20

interface PW-Ether666.1
ipv4 address 2.2.2.2 255.255.255.224
service-policy type control subscriber PM_BNG
pppoe enable bba-group default
load-interval 30
ipsubscriber ipv4 l2-connected
initiator dhcp
initiator unclassified-source
!
encapsulation ambiguous dot1q any

l2vpn

pw-class BRAS-XConnect
encapsulation mpls
protocol ldp
transport-mode ethernet

 xconnect group BNG

p2p TestLab-7600-test
interface PW-Ether666
neighbor ipv4 3.3.3.3 pw-id 666
pw-class BNG-XConnect

This is not working - the sub interface is not picking up the the traffic (all counters 0) 

Is this possible or just not supported ?

(you can't configure BNG on the main interface) - works perfectly on a loop into a BE interface

oh hey benedikt, bng on tomahawk needs to have 6.1.1. that is if you are terminating subs on the tH linecard. if you have a system that terminates subs on typhoon, and you have a tomahawk for core facing non subscriber stuff, you can run 533 or better 534.

regardless in both options 612 or 53x the untagged pwhe cant terminate bng subs.

for the workaround I mentioned with that loopback cable, you would need the ddts from bryan so we can do an untagged EFP and put it into an xcon.

Hi,

Does BNG PWHE+GEO is supported in 6.2.3 for both PPPoE and DHCP ?

yes, for RP-based subscribers.
