Yes, it's not a mistake. The Idea is that you will sort your TLVs by
lexicographic (dst, src) in a Babel packet.
Usually, the source prefix will not begin the same than the destination
prefix cached:
- external destinations are for addresses in our prefix, so in a different
prefix,
- destinations in our local network are probably /128 which are not
source specific.
In both case, we will change the source prefix. Now, consider we re-add both
a "flag" field, and a "src-prefix" field, to memorize the source prefix, and
consider we have 2 (or more) source prefix. Since we have sorted the
message by lexicographic (dst, src), we will have, for example:
(d1, s1)
(d1, s2)
(d2, s1)
(d2, s2)
and anyway, you will be obliged to rewrite the prefix. Now, if you believe
it's important to rethink things and have a more memory efficient protocol,
perhaps having a "dictionary" TLV with, as you explain me (or more precisely
what I understood), with all current TLVs redefined as sub-TLVs... (probably
isn't it the time for that.)
