    yasu's answers to this question are correct. Perhaps
    the text of RFC 2740 would better read "integral number of
    32-bit words" instead of "even multiple of ...".

    Subject: two questions about OSPFv3

    Hi,

    I've two questions about OSPFv3.

    1) In p58 of RFC 2740, it says, "Address Prefix is an encoding of the prefix
    itself as an even multiple of 32-bit words, padding with zero bits as
    necessary; this encoding consumes (PrefixLength + 31) / 32) 32-bit words."
    In my opinion, "EVEN multiple of 32-bit words" means that the Address Prefix
    can be only 64 bits or 128 bits. Then the length should be (PrefixLength +
    63) / 64 * 2 32-bit words. Am I right?

    2) Will Link-LSA be generated for point-to-point interface,
    point-to-multipoint interface or virtual link?

    Thank you.

    Li, Keqin (Peter)
