2. CER Identification OptionA Customer Edge Router (CER) sets the CER_ID to the IPv6 address of its LAN interface. If it has more than one LAN IPv6 address, it selects one of its LAN or loopback IPv6 addresses to be used in the CER_ID. An ISP server does not respond with the CER_ID or sets the CER_ID to ::. Such a response or lack of response indicates to the DHCPv6 client that it is the CER. The format of the CER Identification option is: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | option-code | option-len | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | | CER_ID | | | | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ option-code OPTION_CER_ID (TBD). option-len 36 CER_ID value IPv6 address of CER or ::
I am not an expert when it comes to DHCP. Is there something implicit in the way that DHCP options are designed that makes it obvious that the "CER_ID value" is using ASCII or 128 bits binary to represent the IPv6 address? Because it's not obvious to me from reading the above text.
