A software issue in RSW can cause a corrupted LS update to be generated when there is a large number of links. This issue has been observed with RSW 8.2.0.In an OSPF network with a large number of links (hundreds and more), a change to network configuration is not reflected in the network. After adding a new network statement into OSPF configuration, the new network isn't propagated on other routers in the area. Some OSPF adjacencies may go down after the change, resulting in connectivity issues. Similar situation happens after removing a network from the topology.
This issue has been recognized as a software error and a fix is available from Blue Coat Technical Support.
