Dual-Stack LNS - ppp negotiation fails if no ipv6 prefix assigned by Radius
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
