[c-nsp] MLPPP on dsl

[Joe Freeman]

What's the best IOS to use on a 7206vxr NPE-G1 with 1G Ram, to terminate
PPPoE on LT2tpv3 tunnels into MLPPP bundles?

We're currently running 12.2(16)B on this box, and terminating sessions just
fine. MLPPP performance on DSL/PPPoE sessions is horrible, however. I
suspect it's related to a log message concerning mlppp packets being
forwarded to the wrong interface. I'm trying to get the exact message, but
the customer apparently has their cpe router off.

The cpe device in use is currently a 2610 with two ADSL wics running a 12.2
ip plus image. I've got a 2651xm coming with a 12.3 ip plus image to see if
it works better.

Any help is appreciated.

Here's the 7206 virtual template config-

interface Virtual-Template2
 mtu 1492
 ip unnumbered FastEthernet0/0
 peer default ip address pool default
 ppp authentication chap pap
 ppp chap hostname c7206-2
 ppp multilink

and the 2600 cpe config-

interface Multilink1
 no ip address
 ppp multilink
 ppp multilink group 1
!
interface ATM0/0
 no ip address
 no atm ilmi-keepalive
 dsl operating-mode auto
 hold-queue 224 in
!
interface ATM0/0.1 point-to-point
 pvc 8/35
  pppoe-client dial-pool-number 2
!
interface Dialer2
 ip address negotiated
 ip mtu 1492
 ip nat outside
 encapsulation ppp
 load-interval 30
 dialer pool 2
 dialer load-threshold 1 outbound
 dialer-group 2
 ppp max-bad-auth 3
 ppp lcp predictive
 ppp lcp delay 1
 ppp authentication pap ms-chap callin
 ppp chap hostname user at domain.com
 ppp chap password 0 *******
 ppp pap sent-username user at domain.com password 0 *******
 ppp multilink
 ppp multilink fragment disable
 ppp multilink links minimum 2
 ppp multilink multiclass


Thanks-
