=========================================================================
BayRS and BCC Version 14.20 Revision 2 corrects the following problems:
=========================================================================

CR 120372-2: OSPF
             When adding IP static routes to a host address with a mask of all
             ones, the routes are entered into the router's IP routing table
             but OSPF never imports them, preventing any other OSPF router
             from learning the routes.

CR 125149-1: Passport 2430
             You cannot set the manager password on the Nortel Networks
             Passport 2430 multiservice access switch. This fix applies to
             Revision 4 of the Passport 2430 CPU board.

CR 135370-1: DLSw
             NetBIOS frames received over the LLC protocol are rebroadcast
             from the same Ethernet interface that the frame is received on.

CR 142705-3: DiffServ
             A problem exists in the policing function of the DiffServ static
             filter on the Nortel Networks Passport 2430 multiservice access
             switch. Any traffic exceeding the specified token bucket rate is
             seen as being within the filter profile and, as a result, is not
             handled according to the policy. 

CR 145199-1: OSPF
             During update of the router OSPF link state database, messages
             stating "OSPF: LS UPDATE: BAD LS CHECKSUM" appear in the log
             file. The problem occurs when both of the following conditions
             are met:

             - Both a more specific and less specific route exist for an
               existing IP address.

             - The more specific route is found first and is advertised to a
               neighbor. The less specific route is then found before the
               short interval OSPF timeout occurs. (This timeout exists to
               prevent route flapping by preventing successive advertisements
               from being made too quickly.)

CR 145519-1: DLSw
             NetBIOS Name Query frames received over the DLS protocol are not
             forwarded consistently.
