When OSPF is configured with multiple processes that each redistribute different type routes, LSAs may be created in a process for a route of the type other than the one configured for redistribution into that process.
Incorrect routing information in the network when OSPF converges.
OSPF routing with multiple processes configured. Each OSPF process configured with a different route type redistributed.
Redistribute the leaked route type into the affected OSPF process and use a route map that filters out all routes.
OSPF no longer leaks LSAs between processes redistributing different types of routes. OSPF routes are now created synchronously when the LSA database is updated. If routes are rapidly deleted and re-added, OSPF will send maxage LSAs followed by new LSAs. This is potentially a behavior change where, previously, only a single updated LSA would have been sent.
