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

end
Can anyone help?
