IPoE addressing

IPoE addressing varies with user types.

• DHCP users obtain IP addresses in the following sequence:

  • Obtain IP addresses from the AAA-authorized IP address pool.

  • Obtain IP addresses from the IP address pool configured in the ISP domain if the AAA server does not authorize any IP address pools.

  • Obtain IP addresses in the same network segment as the interface IP address if no IP address pool is configured in the ISP domain.

• IPv6-ND-RS users obtain the AAA-authorized IPv6 prefix from IPoE, and generate an IPv6 address based on the prefix. If no AAA-authorized IPv6 prefix exists, the user adopts the first 64-bit IPv6 prefix of the interface to generate an IPv6 address.

• Other users adopt static IP addresses or obtain IP addresses from the DHCP server without using IPoE.
