Abstract:
In OSPF protocol, Link State Advertisements (LSAs) are exchanged in
Link State Update (LSU) packets to achieve link state database (LSDB)
synchronization and consistent route calculation. The "LS age" field
is part of the LSA header, which is excluded from the checksum
calculation of the LSA. Due to some hardware or software problems,
the LS age may be corrupted and reach the MaxAge prematurely.
Flushing of the corrupted MaxAge LSA may cause flooding storm of OSPF
packets and severely impact the services in the network.
This document describes the problem of OSPF corrupted MaxAge LSA
flushing, and specifies the requirements on potential solutions.
