OSPF LSA Age

OSPF LSA age is 1800 seconds, but I routinely have entries in the LSA table with an age well above 1800. They should be dropping out after 1800s if the router hasn’t received an update containing that network. Instead, they stay there, with age counter climbing higher and higher.

Anyone else see this behavior? Anything that can be done?


This is a problem between routerboards running ros 3.9
