Hello,
We have an LNS (asr1k), dual-stack CPE and Radius server.
Everything works fine if both ipv4 and ipv6 prefix is assigned to CPE by Radius
If we set Radius server not to assign v6 prefix, we expect to build up an ipv4-only session over ppp.
This is not what happens. PPP negotiation fails with the following debug lines:
IPv6 DHCP_AAA: No authorization data from SSS
Vi2.2364 PPP DISC: Non-PPP hang up
some config parts of LNS:
!
no ipv6 source-route
ipv6 unicast-routing
ipv6 dhcp binding track ppp
ipv6 dhcp pool IPv6_DHCP_POOL
ipv6 dhcp pool POOL_DHCP_PD
ipv6 multicast-routing
ipv6 multicast rpf use-bgp
!
!
interface Virtual-Template99
mtu 1460
ip unnumbered Loopback0
ip tcp adjust-mss 1420
no logging event link-status
ipv6 enable
no ipv6 nd prefix framed-ipv6-prefix
no ipv6 nd ra suppress
ipv6 dhcp server POOL_DHCP_PD allow-hint
peer default ip address pool adslpool_1 adslpool_2
ppp max-configure 3
ppp authentication pap AAA_AUTHEN_PPP_noc3x
ppp authorization AAA_AUTHOR_NET_noc3x
ppp accounting AAA_ACCT_NET_noc3x
ppp ipcp address required
ppp ipcp address accept
ppp ipcp no-renegotiation send-termreq
ppp link reorders
ppp timeout retry 5
ppp timeout ncp 30
ppp timeout authentication 30
end
Can anyone help?
Regards,
Antal

Hi Antal
Have you found a solution to this problem ? I'm debugging this since two days and have not found a solution besides giving everyone IPv6...

Have opend a case with cisco. The solution for me is to put
no ipv6 dhcp ppp terminate
in to the global config.
Hope that helps anyone who has the same problem.
