Cisco, IPv6, Multilink PPP

[Ken Mix]

Hello,

I haven't had any issues up to 12.4(20)T.  Sample MLPPP ATM (bonded DSL config):

interface Multilink1
 description To Clearfly (MLPPP)
 ip address 208.88.XXX.YYY 255.255.255.252
 ip nat outside
 no ip virtual-reassembly
 ipv6 address 2607:F3D0:X:YYY::X/124
 ppp multilink
 ppp multilink links minimum 1
 ppp multilink interleave
 ppp multilink group 1
 service-policy output voip
!
interface ATM0/0/0
 description To Clearfly (406458XXXX)
 no ip address
 no atm ilmi-keepalive
 dsl operating-mode auto
 pvc 0/32
  encapsulation aal5snap
  protocol ppp Virtual-Template1
 !
!
interface ATM0/1/0
 description To Clearfly (406458XXXX)
 no ip address
 no atm ilmi-keepalive
 dsl operating-mode auto
 pvc 0/32
  encapsulation aal5snap
  protocol ppp Virtual-Template1
!
interface Virtual-Template1
 no ip address
 ppp multilink
 ppp multilink group 1


Relevant "show int mu1":
  Encapsulation PPP, LCP Open, multilink Open
  Listen: CDPCP
  Open: IPCP, IPV6CP, loopback not set

I have a virtually identical configurations for bonded T1s (minus the virtual-template).

Regards,

Ken

Hi there,

has anyone on this list been running IPv6 on multilink PPP bundles with
Cisco?  We're currently observing problems with IPv6CP negotiation in
this specific configuration.  Haven't investigated thourogly myself yet
due to time constraints, hence I'm wondering if anybody has been running
this setup and might have some pointers (working code release, "special"
tricks and the like...).

best regards,
sebastian
