Jose,<br><br>I would suggest thinking about other means of implementing what you need instead of a routing protocol between the CPE and the LNS.<br>The scalability of routing protocols is not really at the same level as the number of PPP sessions per LNS (which may be 1000's).<br>
<br>Are you aware of the option to download static route entries from RADIUS as part of the user's profile? This would allow you to basically get the same static route on any LNS the user connects to. If they have a failure, and the PPP session goes down, the route would be also withdrawn, and then readvertised from the backup connection.<br>
The backup could be another dynamic PPP session (using the same mechanism) or could be a floating route with a lower preference metric (or higher... depends on how implemented).<br><br>Take a look here:<br><a href="http://www.cisco.com/en/US/docs/ios/12_2/security/configuration/guide/scfathen.html">http://www.cisco.com/en/US/docs/ios/12_2/security/configuration/guide/scfathen.html</a><br>
<br>You should be looking for the 'cisco-avpair = "ip:route=<span class="content"></span>' examples.<br><br>Would this work, or am I missing some critical part of the design?<br><br>Arie<br><br><div class="gmail_quote">

<div style=""><div>Hi Arie,</div><div><br></div><div>thanks, yeap, using a routing protocol between the LNS and CPE, users are then entering the L3 MPLS/VPN (using vrf Radius attributes). The idea is to improve convergence and backup functions</div>
<div>adding a routing protocol. Unfortunately there is no much info about. QoS LNS<--->CPE is of course another big issue and we are thinking to use per-session QoS using Radius... </div><div>Any experience would be appreciated !</div>

Are you asking about using a routing protocol between the LNS and the remote user's CPE, or are you talking about redistributing the addresses assigned to the PPP session (either the /32 or a static route) into the VPN?<br>

Hi,<br> <br> we are terminating via L2TP our PPPoE users on a 7206vxr with npe-g1.<br> Customers are then terminating these sessions in a VRF using Radius attributes.<br> Now we are planning to introduce dynamic routing functionality: RIP,OSPF,BGP...<br>
Any info/experiences/ideas/tips with using routing protocols over L2TP ?<br> <br> Thanks in advance,<br> Jose<br> <font color="#888888">--<br> GMX startet ShortView.de.
