I read from the rfc that anycast addresses are derived from unicast addresses, but unicast addresses' interface identifiers(IID) is of EUI-64 format, which is generated by link layer address, so we can indicate a link layer address from a unicast address.

So, how are anycast addresses' IIDs generated. It doesn't comply to the EUI-64 format any more, any one can answer my question?

Thanks.

You can select any address within the subnet as an anycast address, except for the reserved addresses in RFC 2526.
