Configuration and Troubleshooting LAC for PPPoE over L2TP

Introduction:

This document talks about the LAC configuration which terminated PPPoE connection from PPPoE client and based on the username i.e domain, it runnels the user via L2TP tunnel to LNS.

For PPPoE client configuration, visit

https://supportforums.cisco.com/docs/DOC-6050

In this setup, if any user comes in with cisco.com as a domain name as a part of the username ( for exa. ParamPreet@cisco.com) , it will be tunneled to LNS via L2TP. Users with username other than using cisco.com as a domain name will be terminated locally on this router as a LAC.

vpdn-steps.gif

  1. The      client calls/connects the LAC (typically using PPPoE/ATM , modem or an      ISDN card).
  2. The      client and the LAC starts the PPP phase by negotiating the LCP options      (authentication method Password Authentication Protocol [PAP] or Challenge      Handshake Authentication Protocol [CHAP], PPP multilink, compression, and      so on).
  3. Let's      suppose that CHAP has been negotiated in step 2. The LAC sends a CHAP      challenge to the client.
  4. The      LAC gets a response (for instance username@DomainName and password).
  5. Based      on the domain name received in the CHAP response or the Dialed Number      Information Service (DNIS) received in the ISDN setup message, the LAC      checks whether the client is a VPDN/L2TP user. It does this by using its      local VPDN configuration or contacting an Authentication, Authorization,      and Accounting (AAA) server.
  6. Because      the client is a VPDN user, the LAC gets some information (from its local      VPDN configuration or from an AAA server) that it uses to bring up a      L2TP  tunnel with the LNS.
  7. The      LAC brings up a L2TP tunnel with the LNS.
  8. Based      on the name received in the request from the LAC, the LNS checks if the      LAC is allowed to open a tunnel (the LNS checks its local VPDN      configuration). Moreover, the LAC and the LNS authenticate each other      (they use their local database or contact an AAA server). The Tunnel is      then up between both devices. In this tunnel, several VPDN sessions can be      carried.
  9. For      the client username@DomainName, a VPDN session is triggered from the LAC      to the LNS. There is one VPDN session per client.
  10. The      LAC forwards the LCP options it has negotiated to the LNS with the client      along with the username@DomainName and password received from the client.
  11. The      LNS clones a virtual-access from a virtual-template specified in the VPDN      configuration. The LNS takes the LCP options received from the LAC and      authenticate the client locally or by contacting the AAA server.
  12. The      LNS sends a CHAP response to the client.
  13. The      IP Control Protocol (IPCP) phase is performed and then the route is      installed: the PPP session is up and running between the client and the      LNS. The LAC just forwards the PPP frames. The PPP frames are tunneled      between the LAC and the LNS.

Tunnel setup messages along with user session setup messages that are being exchanged between LAC and LNS

vpdn_20980c.gif

The LAC decides that a tunnel must be initiated from the LAC to the LNS.

1.     The LAC sends a Start-Control-Connection-Request (SCCRQ). A CHAP challenge and AV Pairs are included in this message.

2.     The LNS responds with a Start-Control-Connection-Reply (SCCRP). A CHAP challenge, the response to LAC's challenge and AV Pairs are included in this message.

3.     The LAC sends a Start-Control-Connection-Connected (SCCCN). The CHAP response is included in this message.

4.     The LNS responds with a Zero-Length Body Acknowledgement (ZLB ACK). That acknowledgement may be carried in another message. The tunnel is up.

5.     The LAC sends an Incoming-Call-Request (ICRQ) to the LNS.

6.     The LNS responds with an Incoming-Call-Reply (ICRP) message.

7.     The LAC sends an Incoming-Call-Connected (ICCN).

8.     The LNS responds back with a ZLB ACK. That acknowledgement may also be carried in another message.

9.     The session is up.

Note: The messages above used for opening a tunnel or a session carry Attribute Value Pairs (AVPs) defined in RFC 2661. They describe properties and information (such as Bearercap, hostname, vendor name and window size). Some AV pairs are mandatory and others are optional.

Note: A Tunnel ID is used to multiplex and demultiplex tunnels between the LAC and LNS. A session ID is used to identify a particular session with the tunnel.

For L2F, the setup for tunneling a PPP session is the same as for L2TP. It involves:

1.     Establishing a tunnel between the NAS and the Home Gateway. This phase takes place only when there is no active tunnel between both devices.

2.     Establishing a session between the NAS and the Home Gateway.
