PPPoE over FastEthernet subinterface

Hi all,
I have a FastEthernet with 2 subinterfaces, I want pppoe just in one ofthe subinterfaces. I see good examples but with ATM interfaces, no with FE.
any ideas ?
Thanks,
Luis Miguel.

PPPoE Over IEEE 802.1Q VLANs in 12.4T

I am trying to configure PPPoE Over IEEE 802.1Q VLan on a 2811 router with (C2800NM-SPSERVICESK9-M), Version 12.4(24)T8
PPPoE client on FastEthernet0/0 works fine.
interface FastEthernet0/0
no ip address
duplex auto
speed auto
pppoe enable group global
pppoe-client dial-pool-number 1
But PPPoE session is not established on a subinterface with encapsulation dot1Q. It is not even trying to connect to the PPPoE server.
Cisco Feature Navigator says that this feature was added in 12.4T.
Can anybody confirm that 'PPPoE over IEEE 802.1Q VLANs' feature works fine on this IOS?
Thank you in advance!

Below works fine.
vpdn enable
vpdn-group 1
request-dialin
protocol pppoe
bba-group pppoe global
interface FastEthernet0/0
no ip address

pppoe enable group global
pppoe-client dial-pool-number 1
But the same doesn't work over the subinterface:
interface FastEthernet0/0.2
encapsulation dot1Q 2
pppoe enable group global
pppoe-client dial-pool-number 1

Pppoe over ethernet

Hi all.
Does the pppoe over ethernet supported on 7206VXR NPE-G1 gigabit/fastethernet interfaces with 802.1q encapsulation?
Thanks in advance.

Hello Peter,
I know that it is suported on 10 and 100 MB interfaces, not sure about the Gigabit. Check this document for details:

Dynamic bandwidth selection for PPPoE over Ethernet/VLAN

Hello all, hope you are doing great.
I'm planning to deploy PPPoE Server (Cisco Router 7609) for a ISP. This ISP will provide Internet connection for customer over Ethernet.
I have to provide a solution to assign bandwidth to each customer by RADIUS and I find some clues that Dynamic Bandwidth Selection (DBS) should be the answer. Unfortunately, DBS only support PPPoA or PPPoE over ATM.
If you have any experience with equivalent function, please help me. Thank you very much.
Regards,
Hiep Nguyen.

Hiep,
I think I have figured this out. Here is the test config on my PPPoE server:

Backing up ISDN with PPPoE over Ethernet

I have a router connecting to a Fleet77 which presents two interfaces, ISDN BRI and ethernet.
The client wishes to use the ISDN as the prime interface to their ISP with the ethernet (20k) as a backup if the ISDN fails.
Anyone got an ideas on the best way to configure this.
mux's out a sat link via ISDN (BRI) and PPPoE over Ethernet(supports 20k).

Yes, you are correct. In this case, you can use below example to configure the "dialer-watch".
http://www.cisco.com/en/US/products/sw/iosswrel/ps1828/products_configuration_guide_chapter09186a00800872ed.html
However, as I remember, I don't need the dialer-watch and still work, but I am sorry that I forget the way and can't test it at the momnet.
Hope this helps.

PPPoE over EoMPLS

There are 10 DSLAMs;
Neccessary to migrate to MPLS network;
Each DSLAM connected through 802.1Q trunk to the one PPPoE terminator, there are many vlan subinterfaces with PPPoE enable on.
The question: how to tunnel the each DSLAM trunk to one trunk connected to PPPoE terminator?
The problem is EoMPLS is point to point technology.
But PPPoE terminator is in a center of virtual star.

The document has more information about Cisco DSLAMs.

PPPoE over VLANs -- VDSL

Hey,
I have the same issue like described at http://discussions.apple.com/thread.jspa?messageID=8383489
I want to connect a Mac with the internet over a DSL Modem (without Router)
There for the Mac have to dial up a PPPoE connection via vlan 132.
I tried it with Linux and Windows - it works
Is there a solution for it on OS X?
thx
Franz

Hi there,
I have exactly the same issue with 10.7 Lion Server. It looks like the problem is still present in Lion and it is quite a big annoyance, let's hope someone at Apple sees this and helps us out.

Pppoe over port-channels on ios xe

has the ability to do pppoe and QinQ over port-channels been added to IOS XE? as of 2.6 it was not but I cannot find any documentation on 3.1-3.3 to say that it has or hasn't
Does any one use a asr1000 as a BRAS and if so how do you handle redundancy in case of the loss of a primary interface handling your pppoe sessions?

Hi Artyom,
Try removing "ipv6 nd managed-config-flag" and see if it helps.

Carrying PPPoE over MPLS....

We are stuck in a situtation which is as follows:
Customer(PPPoE)------7600----MPLS---BRAS
The PPPoE session is to be terminated on the BRAS (a cisco 7200). The 7600 does not support the PPPoE Relay feature (which would've allowed the PPPoE session to be carryied over L2TP through the MPLS core). I do not want to use a L2 VPN to do this. Any suggestions???

Hey there... I m too stabbing the same problem... though unsuccessfully.. as a temporary arrangement I have installed another 'PPPoE Relay enabled' router... waiting for TAC guys to come back with some answers... would really like to know the solution for this one !!!

PPPoE over airport extreme

Hi,
I'm struggling to connect to the internet using a PPPoE connection, it is fine through a LAN cable but when I try to connect to the internet through the airport card on another computer I can join the network but can't access the internet. The mac which is joined by a LAN cable is connecting to the internet through the built in ethernet. Thanks

The wireless router should be handling the PPPoE duties. After enabled PPPoE on the wireless router you should disable PPPoE on your Mac.

PPPOE over a powerline adapter?

BT will charge a fortune to move the master socket.
Best to get it done when you next move FTTC contracts and the engineer turns up with then new modem etc, give him tea and cake as ask him nicely to move it whilst he's there ;-)

I'd just keep the Modem & Router where it is and Powerline around the place from that. I've got small switched hanging off the Powerlines at the remote end and they work fine.
By doing the powerline in the middle you'll be broadcastin the raw internet packets around the electical grid, fair enough the powerline should AES the data but you'll be getting alsorts of external crap over the powerline, which you'll need to treat as completely on the internet and not be able to use that pairing for anything else around the house.
Just seems a waste of a powerline pair, whereas if you just drop the 'private' side to powerline you can add further powerlines aroudn the house to move the data about.. I've added extra WAPs etc this way to cover black spots for example

PPPoE over bride

Hi,
I have connecting cisco2811 router to cisco7200 router via E1 link >>>
I want my client behind the 2811 router to use PPPoE and terminate them in the cisco7200 router since the 2811 router is not supporting PPPoE server only client...
What I did is, I have configure a brigde group in the 2811 and add the ethernet whcih connecting the client and the serial which is linked to 7200 to the bridge group..
put still I can't see any PPPoE traffic reaching the 7200 router from the 2811??

Thanks for ur responed.
I connect the 2811 and 7200 through v35 serial interface, the bridge in teh 2811 is between the Ethernet and the serial, and in the 7200 between the serial (which is connecting the 2811) and Ethernet (where I enable the pppoe there)..
the pppoe session start behind the 2811 in the bridged ethernet... but nothing seen in the bridged ethernet of the 7200 router!..

PPPoE over VLAN

I'm trying to set up a MacBook as a PPPoE client.
The provider requests me to send vlan tagged pppoe packets,
so I have set up a vlan interface (vlan0) for the ethernet
device (eth0) and added a pppoe interface to the vlan device.
I have connected the dsl modem to the macs eth0.
When clicking "connect" the ppp daemon starts, but after a while it gives up
without a connection. The log says, it cant find a pppoe server.
9/12/08 2:23:02 PM macbook pppd[1860] pppd 2.4.2 (Apple version 314) started by root, uid 501
9/12/08 2:23:02 PM macbook pppd[1860] PPPoE connecting to service '' [access concentrator '']...
9/12/08 2:24:07 PM macbook pppd[1860] PPPoE connection failed, No route to host
If I attach the modem to a vlan capable router, the connection comes up instantly.
Does anyone know if Mac OS X is really able to tagg pppoe packets? Linux and Vista do.
Any comment is very appreciated, thank you.

There seems to be a bug in Apples pppd or in PPPoE.ppp plugin.
When I try to setup the pppoe-connection this way:
pppd plugin PPPoE.ppp device vlan0 noauth defaultroute user username password pw
packets of ethertype PPPoE should go to vlan0. But tcpdumps didnt show any PPPoE packets
on that interface. Instead, all PPPoE communication is beeing sent to the standard ethernet interface en0.
Here is an excerpt of packet headers from the vlan0 dump:
tcpdump -nevv -XX -i vlan0 >tcpdump-vlan0.txt:
No ethertype of PPPoE in vlan, only DNS broadcasts...

Hi Renzo,
PPPoEoVLAN on GEC (LACP mode) is supported as of XE 3.7. I see that you are using XE 3.4 here so I would suggest to move to XE 3.7 and try this feature.
This is a sample configuration for the feature:
interface GigabitEthernet2/1/0
no ip address
negotiation auto
channel-group 2 mode active
interface GigabitEthernet3/1/0
no ip address
negotiation auto
channel-group 2 mode active
lacp port-priority 65000
interface Port-channel2
no ip address
load-interval 30
no negotiation auto
lacp max-bundle 1
lacp fast-switchover
interface Port-channel2.200
encapsulation dot1Q 200
pppoe enable group global
interface Port-channel2.500
encapsulation dot1Q 500 second-dot1q 1500
pppoe enable group global
As you can see, both PPPoEoVLAN and PPPoEoQinQ are supported.
Hope this helps.
Best regards.
