[Bug 1512509] Re: slaac via pppoe fails with sif6addr failed

 

** Description changed:

  trying to configure ppp0 via SLAAC by adding
  
  +ipv6
  ipv6 ,::3
  
  and increasing the debug level, i find in the logs:
  
  Nov  2 23:03:37 zotac01 pppd[3796]: cif6addr: ioctl(SIOCDIFADDR): No such address
  Nov  2 23:03:37 zotac01 pppd[3796]: sif6addr: ioctl(SIOCADDRT): File exists (line 2607)
  Nov  2 23:03:37 zotac01 pppd[3796]: sif6addr failed
  Nov  2 23:03:37 zotac01 pppd[3796]: sent [IPV6CP TermReq id=0x2 "Interface configuration failed"]
  
  ppp0 has two ipv6 ips, both local,
  old ip remains linked
  no default route is received
  several IPV6CP ConfReq appear in the log not changing any parametr of the link
  a further configuration of the interface via dhcp is not possible because the interface never becomes able to transmit ipv6 packages.
