ISP DHCPv6 vs SLACC for WAN assignment
There is a bit of a debate at the moment (company internal) on the best way to deploy an IPv6 address to our WAN CPE clients from the PE.
SLAAC vs DHCPv6 on WAN
(Esentially we are sending down IPv6 PD pool to the CPE's anyway where they can dish out SLAAC leases to their clients, like xbox or whatever.)
We have labbed 2 senerios for assigning the WAN IP. Stateless - SLAAC and statefull - DHCPv6
Either works as the PD pool config is the same, except DHCPv6 doesnt advertise a default route, but its not really an issue as our provisioning procedure will inject that anyway.
I just wanted to get peoples opinion on their experiance in deploying IPv6 down to the CPE's (WAN) for a SP. Which works best, Stateful or Stateless?
Is it easer for you to track who gets what with the v6 server? or doesnt it really matter so much. Thoughts?
