I have two question abbout premature used in isis/ospf.
1 ) I think that a router set self-originate lsa's age as Maxage then flood out to quickly flush is premature.
But when a lsa that is not sel-originate resides in database,will reach Maxage for some reason, and now,
if the router will flooding it ? if it will,is this violate the rule that only origante can premature ?
2 ) In which case, premature will trigger ?
