Subject: [radext] Q on RFC6158 & draft-ietf-radext-ipv6-access

What is the definition of the 'IPv6 prefix' (basic data type) in the section 2.1 of RFC6158?

Is it the same as the basic data type of 'IPv6 address'?

BTW, there has some words about the 'prefix' in the definition of 'Route-IPv6-Information' (attribute), section 3.3 of draft-ietf-radext-ipv6-access-06 shown as follows:

<quote>
   Prefix Length
      8-bit unsigned integer.  The number of leading bits in the Prefix
      that are valid.  The value ranges from 0 to 1.  The prefix field
      is 0, 8 or 16 octets depending on Length.

   Prefix
      Variable-length field containing an IP prefix.  The Prefix Length
      field contains the number of valid leading bits in the prefix.
      The bits in the prefix after the prefix length (if any) are
      reserved and MUST be initialized to zero.

Does the above prefix comply with the basic data type of 'IPv6 prefix' mentioned in RFC6158?
