Cisco WAN :: 2811 Using Sub-interfaces And PPPOE On ADSL
Apr 26, 2013
I am trying to get my Cisco 2811 to authenticate four DSL connections and load balance them by attaching the four DSL to a switch (each DSL going to a seperate VLAN) and then trunking all four VLAN's to a ethernet interface on the 2811. My issue, I can not get more than one DSL to authenticate at a time, for example Dialer1 will connect and then it will disconnect and Dialer2 will connect, etc... I have the modems in bridge mode and I am using seperate user/pass for each DSL account and I have verified that the user/pass are correct.
Below is my config from the router and a couple of messages that came across the console.
*Apr 27 01:12:11.915: %DIALER-6-UNBIND: Interface Vi2 unbound from profile Di1
*Apr 27 01:12:11.927: %LINK-3-UPDOWN: Interface Virtual-Access2, changed state to down

I have a Cisco 2811 router with 2 ADSL interfaces and we have 2 internet lines associated with it. One is with Telstra and one is with iiNet. All internet traffic from inside the office is routed through Telstra line. The iiNet line is used for incoming emails, establishing VPN etc. The problem is that we are not able to "PING" the iiNet's IP address from the outside world however, PING works for Telstra IP. What do I need to configure on the router if I want to PING and Putty in the router using both Telstra's and iiNet's IP from outside world?

I get stuck in one case. One of my customer has two FTTH lines. I have to config PPPoE in routers. In one line I config succesfully, but one line never up. I call to ISP they ask me to config extactly VLAN id 10 in the physical subinterface. But in subinterface there is no command "pppoe-client dial-pool-number". I check the old modem FTTH, they also config VLAN 10 in Wan interface. I tell ISP why we have the same two FTTHs, but two differrent config ways. ISP says because the two line run in two different infrastructure, two different devices. I don't know how to do now? stay in customer side or ISP side. Here is my PPPoE config:
interface FastEthernet0/0
no ip address
duplex auto

We are using SRP527 routers with PPPoE ADSL connections. From the SRP527 we create an IPSec tunnel to our core routers (Cisco ASR). We are wanting to change the IPSec tunnels to L2TP, and I need to know if this can be done from the SRP527. I cannot find any L2TP configuration options in the setup options.Can the SRP527W act as an L2TP tunnel initiator over the ADSL PPPoE interface?

I had a question regarding the Cisco 2811. I tried fitting an NM 2FE-2W card and the fast Ethernet interfaces of the module never get recognized. Is there a special command to enable it or isn't the module supported at all by the router. If not , is there a way to have the router possess more than the 2 Fast Ethernet interfaces it already has? Let me know if any more info is needed from my end.
Another question I have out of curiosity. Is it possible to make the controller T1 port of a VWIC 1MFT-T1 or a VWIC 2MFT-T1 act as a fast Ethernet.

I have a task of setting up bandwidth limit on the 2811 router Fastethernet interfaces.The scenario is:We have a 4MB Internet connection and would like to allocate bandwidth usage to users.
Fastethernet 0/0 needs to be set with 256KB output and 2048 input. This is going to be connected to a wireless router. Fastethernet 0/1 needs to be configured with 2048 output.I could also use SDM if that's easier than using CLI.

I've got an issue with SNMP and netflow tools. They are displaying different data for the same (sub)interfaces.I've got metroethernet link which connects root A (Cisco 7606, 12.2(18)SXF8) and root B (Cisco 2811, 12.3(11)TS). MPLS is configured on the link (behind root B there is no more MPLS). I'm attaching root configurations (I've ommited parts of config).Interfaces are:
Root A - gi2/6.2144
Root B - fa0/1
I've configured SNMP and netflow on both devices. I'm using two SNMP tools (CA Spectrum and eHealth) and two netflow tools (CA NetQoS Reporter Analyzer and Fluke Networks NetFlow Tracker) to collect the data. SNMP tools show the same info for defined (sub)interface.Netflow tools also show the same info for defined (sub)interface. I'm attaching reports from one SNMP tool and one netflow tool for the same time period.
1. Looking at SNMP tool, it can be seen quite amount of that data in both in and out direction.
2. Looking at netflow tool, it can be seen quite amount of that data in out direction, while in direction shows small amount of data.
I'm aware that Cisco has difficulties with SNMP counters on subinterfaces. I'm also aware that MPLS netflow has its own difficulties.Root B netflow configuration is quite simple as it has just 2 interfaces to configure netflow on (Fa0/0 and Fa0/1). So I would guess SNMP and netflow data should match, but they don't. When you look at SNMP tool reports for roots A and B, it can be seen that traffic volume is practically mirrored.

I have a Cisco 877 doing PPPoE through a ISP supplied modem that is in bridge mode (long story). When the DSL drops on the modem it takes around 5 to 10 mins for the 877 to redial the connection.
Here is the config I'm running:
interface Vlan1
description PPPoE-Interface(WAN)
ip address dhcp
load-interval 30
pppoe enable group global
pppoe-client dial-pool-number 1
[code]....
Its possible some of that config is redundant but I've tried as much as I can see online.

Cisco 877W. I configured it for PPPoE. But once I plug in the ADSL line, the dialer interface will get IP Address. But after like 2 minutes the PPP link will go off and I will get this log message: "Interface Vi1 unbound from profile Di1".

Is it possible to set up a pppoe client on a VLAN interface, or a switch interface associated to an VLAN?. For example, in a 881 ethernet router, could I configure a pppoe client on any of the lan interfaces in addition to the pppoe client configured on the WAN interface?.

Trying to find a way to configure my 851 for home use. My internet provider use PPPoE with PAP and althrough I found many configuration options they all are incomplete...or i cant find the logic behind those commands. First of all I need to say what I need:
1. Configurate my int Fa4 (WAN) with pppoe so when i insert my ISP cable in it it will negotiate and take IP.
2. Configurate DHCP on LAN (Fa0-3) so that when I insert my PC it will take a fake IP.
Here is the place where i found some conf examples: [URL] and I have some questions:
1. MTU - Should I use the 1492 value or the "pppoe-client ppp-max-payload 1500"?
2. ip route 10.10.25.2 255.255.255.255 dialer 0 - How can i set an IP route when my connexion informations only come after i connect? (Because is PPPoE)?
3. I cant configurate the DHCP because I dont know the default route, I dont know the DNS, and i dont know the default gateway because I dont know them due to PPPoE !

I am using ASA 5505 with firmware 8.2(2). My ISP uses PPPoE as a WAN connection protocol. There is a problem with getting PPPoE session started on my ASA 5505. The debug output says that after negotiation of PPP-authentication protocol ASA receives a PADT packet from ISP’s concentrator. To get more information I captured all packets on outside interface with WireShark. Packet-dumps (in .pcap format) are attached in this post. I have tried all possible combinations of PAP/CHAP/MSCHAP values in “vpdn group MYGROUP ppp authentication” command. If you take a look at the packet-dumps you can see, that in case of “PAP” – ISP’s concentrator rejects negotiation (PAP is not supported by my ISP). In case of CHAP/MSCHAP (that ARE supported by my ISP) – ASA acknowledges the using of MSCHAP v.2 PPP-auth protocol, which is actually not supported by it…
Judging by MAC-addresses of ISP’s concentrators it is visible that Cisco’s equipment also is used.
The questions is: Why ASA acknowledges using of unsupported ppp-auth protocol during negotiation and what I need to do to resolve this issue? (ISP’s support says, that they cannot change PPP-auth protocol negotiation order. Also they says that I need to contact with manufacturer of my equipment).

I have cisco router model 1921 , how can i terminate my existing pppoe connection to 1921, so that my other LAN users can use internet.
1- One cable (RJ45) which is comming from ONT has connected with Integrated WAN Port on router.
2- One cable (RJ45) which going to my LAN switch has connected with Integrated LAN Port on router.
Now i need to configure my router, so that i can give internet access to my LAN users. I red cisco's guides but not clear regarding configurations, because in guides they use modules to configure pppoe. But i am not using any module, i am simply connecting one cable for WAN and one for LAN.

is it possible to configure a Cisco 878 Router to act as a device(router) between a DSL Modem and the LAN ?
There is the following scenarium: "Deutsche Telekom DSL Modem -> Cisco Router 878 -> LAN"
DSL is an SDSL Connection with a static IP address.

I have recently gotten a cisco 1941 router running version 15.1(3)T, and am trying to configure the router as a PPPoE server for access via a vlan on one of the gigabit ethernet ports.I currently have a cisco 2620 router (version 11.3(2)XA4) with the following relevant configurations:
vpdn enable
vpdn multihop
vpdn domain-delimiter @ suffix
!
vpdn-group pppoe
[code]....
I am trying to duplicate this (all but IP addresses) on the new router, but there are some options that do not seem to exist in this particular software/hardware combination. Specifically,
vpdn-group pppoe
accept-dialin
protocol pppoe
does not accept "pppoe" as a protocol, only allowing l2tp. What has changed, and what the proper configuration is.

I'm trying to get a PPPoE config working on an 1841. Running c1841-advsecurityk9-mz.124-3i.bin . I tried c1841-advsecurityk9-mz.151-4.M4.bin but it has even less protocol options.
I used a walkthrough but it suggests the following fragment which doesn't work because there is no "protocol ppoe" command available on my system. Perhaps there is a simpler way to do this? I tried c1841-broadband-mz.151-4.M4.bin but it doesn't seem to have ssh available.
vpdn enable
vpdn-group 1
request-dialin
protocol pppoe

I have a ZyXel P-660R-D1 DSL modem, and lately I've been experiencing random outages. I'm not super knowledgeable when it comes to the technical side of networking, but I know enough to look around the modems GUI and recognize when something isn't right. I'm pretty sure this is not a problem on my end, but I'd like to hear a few other peoples opinions. Basically I have four lights on the modem: Power, Ethernet, DSL, and Internet. DSL is the light that indicates connection to the PPPoE server, and lately it will just randomly drop. I've never experienced problems connecting with the PPPoE server until just recently. Every once in a while my Internet light will drop, and a simple reset will take care of it, but rarely am I ever not connected to the PPPoE server. One day it was down for three or so hours, one day for nine, another day it cut in and out for about four hours, and today was another nine hour day. how it works is that my username and password are verified through the ISPs PPPoE server, and then I am granted access to the web. I'm lead to believe that it's nothing on my end because all troubleshooting methods fail, it just randomly fixes itself several hours later. The first nine hour stretch I experienced I thought may have been because of maintenance or some other unforeseen circumstance, but it has happened a few times now so I'm not too sure. My provider, Earthlink, hasn't listed any 'Known Outages' on their site, but then again they never do.

Two days ago our desktop computer stop having internet access. I called my ISP about this problem and they said that everything was fine with my router and that it might be a bad cable. I bought a new cable and it wasn't the cable. I called my dad's friend who works with computers and he said that he thought the NIC was bad. So we went to Staples and bought a Gigabit Ethernet PCI Adaptor, because that would fix the problem, well i installed all of the software and it didn't and we're stumped on what to do.
Our laptop still gets wifi however when I try to connect on my desktop it says that it can't connect through the WAN miniport PPPOE. It gives me error 815

I just switched to DSL from cable internet and am having some trouble setting up my router with the new internet service. DSL modem-->Router-->Network with PC and PS3
ISP is ATT
DSL modem is a TP-Link 8616
Router is a D-Link DIR-628
I put my ATT username and password into the router but it never completes a connection to the internet. I was able to create a soft PPPoE gateway connection through my computer using my username and password, but I want my router to do this, not my PC. How do I get my router to connect directly to the Internet connection rather than having my PC connect? My setup would be fine as-is if I just had 1 computer but I also want to go online with my PS3, and it won't connect like my PC will, even after putting the username/password in.

A PC connected to a Cisco 877 router and 877 router is connected to another router (7301) via GRE tunnel,Cisco 7301 router is a NAS server and is being used as a PPPOE server.If user create a PPPOE connection on his computer and dial with a username/pass we want to send the PPPOE traffic to 7301 router, so 877 router should pass the PPPOE traffic to 7301 and user will be able to connect,User -> 877 -> 7301(PPPOE server).

I'm trying to configure an Cisco 1841 with IOS 12.4 to an FTTH conection.I would configure PPOE protocol in the vpdn-group 1 but I can't see this option in the command line,I have read about the command "bba-group pppoe global" but i'm not sure if it has the same result. It's valid? How can I use the bba-group pppoe global¿? I need to use it with a virtual template?

I am trying to get a Cisco ASA5505 to get onto the internet using PPPOE through a Netgear DG384 ADSL router. I have the Netgear in Modem only mode - if you put it in Router mode internet access works fine. When I change it to Modem mode, the error I get on the ASA is PADI timeout. Looking through the config I think I am missing a Global NAT??Also not 100% on the best way to set the IP - we have a static IP from the ISP. Do you set the interface to use DHCP and get this address or set it statically? Then do you put the setroute option or put in a static? [code]

I am tyring to remotely diagnose a troublesome ASA5505
It is connecting via PPPOE and the original suscpicion was that the PPPOE was going down during heavy loads during the day, i.e 9am and lunchtime. I suspected MTU and have verified the MTU outside is set to 1492
However further troubleshooting doing a remote ping to the PPPOE address indicates that this does not drop at all.
When remoteley connected to the ASA my session dies and any outbound internet fails, then in a few minutes it comes back.
all the time the PPPOE line stays up?
One thought is that although the line does not go down it is being crippled with traffic and just getting so unresponsive it appears it has died.
