The output shows that Router B has assigned an IP address to the host.
Example: Assigning the PPPoE server IPv6 address through
ND and IPv6CP negotiation
Network configuration
As shown in
, configure the PPPoE server to advertise the following information to the host:
•
IPv6 prefix in RA messages.
•
IPv6 interface identifier during IPv6CP negotiation.
The host uses the IPv6 prefix and IPv6 interface identifier to generate an IPv6 global unicast
address.
