Cisco LAC/LNS question

seeing this thread, I was wondering ... we have our LAC/LNS working fine
so far, even with v6, but we have only tested with Cisco CPEs for now
... on the LNS side, I took this road:
ipv6 unnumbered Loopback1
ipv6 mtu 1480
ipv6 nd reachable-time 30
no ipv6 nd ra suppress
peer default ip address pool dsl-pool
peer default ipv6 pool dslv6-pool
With a CPE that has ipv6 enabled on the dialer, an address is assigned
correctly, and the CPE is reachable via v6 just fine.
>From some comments or how-tos I saw at other places, I take it this way
will not necessarily work with any v6-capable CPE. E.g., Fredy Künzler
held a nice presentation at DENOG#2, which showed the DHCPv6 usage (
So what's the recommended way of handing out dynamic IPs to customers?
Can both the "Cisco way" I used and DHCPv6 be combined with the CPE just
using either which one suits them?
