PPP IPv6

[CliveAllen]

Hi all, I will try and explain this as best as I can, and with a basic flow overview:

Cisco 2691 (PPP Client) --> Cisco 2691 (LAC) --> Juniper MX240 (LNS)

Okay, with IPv4 set as a pool on the LNS everything works fine. I get an L2TP tunnel, authentication works against the AAA.... absolutely spot on.

Now, I have changed this to be IPv6 pool at the LNS and I have nothing working. I have been reliably informed (and am almost certain myself (note I said almost)) that the Juniper side is configured correctly with NDRA etc.... So, I wanted to check if I have the Cisco side configured correctly for IPv6 as something is not right somewhere...

PPP Client configuration:

interface Serial0/0
 ip address negotiated
 encapsulation ppp
 clock rate 2000000
 ppp pap sent-username testuser@network.com password 0 testing123

ip route 0.0.0.0 0.0.0.0 Serial0/0

LAC Configuration:

vpdn enable
!
vpdn-group TESTNETWORK
 request-dialin
  protocol l2tp
  domain network.com
 initiate-to ip 195.80.0.29
 local name 21HEX
 l2tp tunnel password 7 071B245F5A001702464058

interface FastEthernet0/0
 ip address 195.80.0.30 255.255.255.252
 duplex auto
 speed auto
!
interface Serial0/0
 no ip address
 encapsulation ppp
 serial restart-delay 0
 ppp authentication pap callin

Any help would be greatly appreciated. Thank you

Here's a response....

I Configured an IPv6 nd prefix on the serial interface and suddenly a tunnel came up. Now, the problem was the address I got on the PPP Client was not what we had supplied as a pool. We got the FE80::212:FF:FE8D:8980 address (not sure if that is the equivalent of a 169 in IPv4..... )

Anyway, it still does not work as we cannot ping anything through the tunnel......

Any help please
