It's a mistake. The earlier draft had the prefix length as a full octet. The
mistake was made in the conversion to the ascii art. I'll be re-issuing with
the field changed to 8 bits.

Subject: ipv6 prefix length.

Chris,

I'm not sure if this was dicussed before. 

In IPv6 Reachability TLV, The Prefix Length field consists of 6 bits. 
So we can store the maximum unsigned value of 63(2^6 - 1).

which means we cannot have more than prefixlen of 63 in ipv6. Right?

Don't we need to be able to store the maximum prefix length of 128?

Please enlighten me on this issue.

Thanks
Nagi.
