Re: PPPoE with IPv6

I have to admit that I am having a problem repeating my earlier setup.
 The client R1 is not showing the OPEN mode but now always SOLICIT.

R1#sh ipv6 dhcp interface
Dialer1 is in client mode
  State is SOLICIT (7)
  Retransmission timer expires in 00:00:40
  Rapid-Commit: disabled

I can't say though that I have any experience with DHCPv6.

I think though the routing was working as Rick was surmising.
