Hello,
Can anybody explain me briefly: why we need an explicit number of LSAs in
LS-Update packet? Why we cannot parse this packet byte-by-byte as
DD/LS-Ack
packets?
Hi Vladimir,
I believe it is mainly historic. Since router and network LSAs are
variable length,
someone saw the requirement to ascertain the number of LSAs in an LS update
without parsing the packet. However, I can't see a strong requirement
for this.
In any case, it's not something we're going to change now ;^)
Hope this helps,
Acee
