Hi all, According to the section 7.1.5
we have to construct list of area addresses for the area while processing LEVEL1LSPs and include it in LEVEl 2 LSP number 0. So when a system is no longer advertising an area address which it has advertised 
earlier, shouldn't we remove that area address from our list and regenerate 
LEVEL2 LSP number 0? Similarly when the LSP in which an area was advertised  ages out 
shouldn't we remove the area address that we learned from that LSP and regenerate 
LEVEL2 LSP number 0? 
But note 14 of section 7.2.11 says that we have to keep area addresses advertised
by systems without considering whether they are currently reachable or not Why should we keep it? Since we restrict the number of area addresses shouldn't we
ensure that what we are keeping is only uptodate information? please help
Thanks in advance
Aravind
