================================================================
12.05 Revision 1 corrects the following problems:
================================================================

CR 30736: XB
          When an SRF is received on a router interface which has both PPP and
          Wellfleet Std. circuits configured for source route bridge/
          translation bridge, a bus error occurs. 

CR 32268: X.25
          Datagram larger than 1915 bytes causes IP fragmentation problems.
 

CR 33564: DVMRP
          The "ip dvmrp_caches" command should support pattern matching. 

CR 33567: DVMRP
          The "ip mtm" command should support pattern matching.

CR 34438: Protocol Priority
          When an outbound protocol priority SNA traffic filter is enabled on
          a sync circuit, attempting to communicate over the circuit can cause
          the sync state to report the circuit as down until the traffic
          filter is disabled.

CR 76003: ATM
          After a physical disconnect on an ATM interface, the ifEntry
          instance is removed.

CR 87367: X.25
          While restarting many IPEX sessions, a fault occurs.

CR 87580: IP
          In an environment where thousands of routes are flapping often, it’s
          possible for BGP to mark a route as unreachable, and then as
          reachable, before IP has had a chance to completely finish updating
          all slots with the unreachable information. This can cause a bus
          error on the router.

CR 87645: 100BASE-T
          Lancast 100BASE-T transceiver fails operating system diagnostics.

CR 87801: N/A
          The operational status of the second Ethernet port of a dual
          100BASE-T card does not display correctly.

CR 87829: PPP
          After a successful CHAP authentication on a PPP leased line
          connection to a router supporting only inbound authentication, a bus
          error occurs.

CR 88495: X.25
          When you configure a small number of virtual circuits when starting
          X.25, an insufficient quantity of PDU buffers is made available.
 

CR 88632: ARN boot PROM
          ARN fails to boot intermittently due to erroneous entry into
          diagnostic mode. ARN boot PROMs need to be upgraded to version 1.27.

CR 89524: IPX
          When deleting IPX from an Ethernet circuit under load, there are
          numerous virtual buffer memory errors and bus errors.

CR 89702: MIB II
          When a physical connection to a 100BASE-T Ethernet or gigabit
          interface goes down the instance associated with that interface
          disappears in the wfIfEntry MIB as well as the MIB-II ifEntry.

CR 90108: IPX
          RCONSOLE and some Lotus Notes applications do not work when IPX
          traffic traverses a DOD hot standby circuit.

CR 93222: DVMRP
          Disconnecting the Ethernet cable from a router causes a watchdog
          timeout as soon as the router cleans up its DVMRP route entry.

CR 93483: GAME
          When polling the router log every second for an extended period of
          time on a node with interfaces configured as either an ATM
          interworking or an ATM trunk, the ATM slot can reset.

CR 96189: IP
          Routers configured for IP RIP announce policy filters to only
          advertise one route with a particular metric may advertise the route
          as unreachable. This occurs when the Networks List of the policy is
          empty, indicating that the policy should match all routes in the
          routing table. It appears that if the first route in the routing
          table is unreachable, the network(s) in the Advertise List are also
          advertised as unreachable, rather than being advertised with the
          metric specified in the policy.

CR 99067: OSPF
          Under heavy CPU utilization, OSPF may fault.

CR 100000: ATM
           Sending large packets through an ATM PVC that is overutilized and
           clipping frames on transmission will cause a virtual buffer memory
           error. 

CR 100556: ATM
           Router does not respond or challenge an LE_NARP request for its
           interface MAC address.

CR 101014: IPX
           Disabling split horizon sometimes creates a corrupted IPX host
           entry table on adjacent routers.

CR 101568: PPP
           When the IP interface of a Cisco router is shut down in a multilink
           with a Nortel Networks router, the Nortel Networks router shows
           extra lines when it is reenabled. 

CR 102358: DLSw
           The router does not establish a connection with RFC 1795 due to
           SDLC maximum data size being hard coded to 512 bytes. When this
           occurs the host receives the test poll with the small LF, it then
           sends an XID with a maximum I-frame bits also set to 516 bytes and
           the XID negotiation fails.

CR 102428: VINES
           The router is installing its own VINES NetID as next hop after
           receiving a redirect with its own NetID as the gateway which
           corrupts the VINES route table.

CR 102477: VINES
           If VINES is disabled globally on a router in a redundant network,
           the network ID of that router will not be removed from its
           neighbor’s routing table, so that the neighboring router continues
           to advertise the router as reachable.

CR 102685: VINES
           Connectivity may be lost to VINES routers or servers when a VINES
           router is bounced in a multipath environment.

CR 102838: PPP
           A bus error occurs on the router during start up of a NetBIOS
           session while using SR/DLSw on the local TR interfaces with 
           ISDN/BRI with MLPPP and WCP enabled, and with an outgoing traffic
           filter (log or NoCall/NoReset for OSPF or RIP).

CR 103342: Technician Interface
           Running readexe bn.exe on a single-slot ARE BLN can cause a VBM
           error to occur if the More option is On and there is no session
           activity for 10 seconds. 

CR 103944: VINES
           VINES is sending ping responses with a calculated hop count rather
           than a max hop count. This causes packets to be zero-hop dropped on
           the return whenever there are multiple equal-cost paths with
           different hop counts. 

CR 104246: ATM
           The LE_ARP entry in the wfAtmLeArpEntry may point to a non-existent
           or released VC entry in the wfAtmVclConfEntry due to a timing
           issue.

CR 104816: WCP
           When a router is configured with frame relay and WCP and is
           rebooted, a Bus Error or Tag Violation may occur if at the same
           time the FR link is unstable.

CR 105045: BGP
           A fault may occur when deleting ATM PVC service record that is
           configured with BGP.

CR 105280: IPEX
           The router can’t establish more than 10 sessions simultaneously.

CR 105294: VINES
           VINES may go to buffer depletion for an extended period when
           configured in a redundant topology with equal cost routes. This
           generally occurs when disabling and reenabling multiple VINES
           routes that share a common segment or when rebooting multiple
           routers on a common segment.
 

CR 105561: IPX
           Connectivity to the host is lost when a host entry still exists in
           the IPX host table even though packets can’t be forwarded to that
           host. Connectivity can also be lost when the host is no longer in
           the host table and it cannot be added again.

CR 105577: SWSERV
           Toggling a primary circuit and a backup circuit causes a bus error
           to occur. 

CR 106013: BGP
           After the preferred route is lost, the BGP route does not propagate
           to other slots. The route only works on the interface that
           initiated the change. 

CR 106061: RIP
           Tag violations may occur on all IP slots when booting a router with
           RIP configured.

CR 106374: SDLC
           When you restart TCP on an SDLC PU2.1 client to a token ring host,
           an orphan buffer fault occurs.

CR 106602: Frame relay
           Performance on frame relay over HSSI suffers 50% of line speed with
           64-byte packets. 

CR 106710: Spanning tree
           Need to remove spanning tree debug message.

CR 106735: X.25
           An interface configured with X.25 faults and resets during multiple
           call disconnect requests.

CR 106781: Learning bridge
           When an ARE slot disconnects and resets, bridging performance is
           degraded until the bridge is restarted.

CR 106868: SRB
           In a TR LAN emulation environment with source routing, the router
           may lose IP connectivity to an endstation when it gets the first
           frame from another endstation with a routing information field
           (RIF) and the direction bit set to backward.

CR 106888: OSPF
           Disabling and reenabling an OSPF area using Site Manager in dynamic
           mode causes the Authorization Type not to form an adjacency between
           interfaces.

CR 107143: ATM
           The router is not responding to LE_ARP destined for its own MAC
           address 802.5 elans. This condition affects performance because the
           router sends unnecessary traffic to other LECs and creates
           congestion on the bus.

CR 107164: Frame relay
           Bus errors occur on the FRE processor before it goes into diag mode
           when you bring down a frame relay interface with an HSSI card
           configured with IP. This occurs whenever the router brings down the
           frame relay interface after not receiving the LMI status messages.

CR 107477: DVMRP
           When a DVMRP interface is repeatedly bounced, data is not forwarded
           and the interface is not listed in outbound circuits of DVMRP cache
           or MTM cache.

CR 107503: Telnet
           If a Telnet session is stopped while running a batch file, an error
           occurs on that router slot.

CR 107515: IP
           When connecting to a circuitless IP address of a router using TCP,
           the router sets the TCP maximum segment size to 65501 which is not
           compliant with RFC 879.

CR 107675: DVMRP
           When a non-dominant router becomes the dominant router and
           subordinate routers are contained in its loop neighbor list, the
           newly dominant router will not graft traffic.

CR 107703: IGMP
           Multicast data packet gets duplicated on a DVMRP router where MTM
           has outbound cache entry on an inbound circuit. 

CR 107806: LLC
           The router does not respond to SABMEs with a UA (unnumbered
           acknowledgment) packet, which prevents DLSw traffic.

CR 107829: OSPF
           In the link state database, the cost of an OSPF route to an
           aggregated group of networks is represented as the closest network
           interface. According to RFC 2328, the cost should instead be the
           distance to the furthest network out of the group of networks
           aggregated together. 

           The new MIB attribute, wfOspfAggrUseMaxCost, allows you to
           determine whether to use the minimum or maximum cost. By setting
           this attribute to 1, you can enable the OSPF route cost to
           represent the distance to the furthest network in the aggregated
           group. Otherwise, accept the default, 2 (Disable), for the OSPF
           cost to represent the closest network in the group. 

CR 107938: ATM
           Router does not cleanup the ATM circuit when port is dynamically
           deleted using Site Manager.

CR 108091: DVMRP
           Data can be lost when the router learns a subordinate route from
           one neighbor router and receives a poison reverse from another
           router that resides in its neighbor list. 

CR 108407: IP
           Extended traffic filters do not work on an ARE once greater than 31
           filters have been added.

CR 108597: DVMRP
           When an inbound cache is reused, a loss of data can occur.

CR 108649: DVMRP
           The multicast table manager (MTM) cache can get out of sync: it
           represents an inbound interface using its outgoing slot mask even
           though the inbound interface doesn’t have any outgoing circuits.

CR 108689: DVMRP
           The router discards the prune packet if an active prune from
           the downstream neighbor already exists. Traffic can also be blocked
           for a period if the new prune time value is less than the current
           prune time value.

CR 108690: ATM
           If you delete an ATM interface from a router with the cable
           disconnected from the switch, then ifEntry will still show that the
           interface there.

CR 108776: DVMRP
           A temporary data loss can occur when prune is sent with an
           incorrect time value that is smaller than current prune time value.

CR 108850: DVMRP
           Outbound slot is not communicated to inbound slot, and data is lost
           as a result.

CR 109311: IP
           The router sends unnecessary ICMP error messages in response to
           broadcasts received from a non-local source.

CR 109636: MOSPF
           When there are more than 20 IGMP join entries defined, invoking the
           "show mospf fwd" command causes a bus error to occur on the router.

CR 109640: MOSPF
           Invoking the "show mospf fwd" command does not show more than 13
           downstream forwarding entries.

CR 109873: TI-RUI
           Invoking the "save log" command through SNMP does not complete
           successfully and can cause a fault.

CR 109909: Boot
           Booting the router multiple times with either a named boot file or
           typing "boot" causes orphan buffers in the log. Also, any router
           slots that do not contain a flash card will stop loading protocols.

CR 110168: ATM
           Traffic originating from an 802.5 LEC with source route bridging
           does not utilize data direct VC.

CR 110427: Filters
           After creating a traffic filter template with at least 22 IP ranges
           (any combo of source or destination addresses) and a TC destination
           port, then applying this filter to an Ethernet circuit configured
           for IP/RIP, the show ip traffic filter command yields results that
           make it look as if the filter is corrupt. 

CR 110783: ATM
           The LAN emulation client (LEC) responds to LE_ARP requests for LAN
           destinations it does not represent.

CR 111085: CSMA/CD
           When two ARNs are connected back-to-back with a crossover cable and
           the user issues a warmboot on an ARN 10Mb/sec Ethernet port
           (motherboard or daughter card), the partner ARN never gets informed
           of the warmboot and IP doesn’t start on the partner router.

CR 112123: DVMRP
           DVMRP may fault when deleting a cache entry.

CR 112143: IGMP
           If you disable a multicast circuit where an IGMP static group is
          configured, this router sends prune to a neighboring router. Then,
           if you reenable that DVMRP circuit, the router keeps pruning
           traffic.              

CR 112282: DVMRP
           If you remove a downsteam neighbor, the router may fail to remove
           it from the DVMRP pruned neighbor list, causing temporary data
           loss.

CR 112402: IPX
           When IPX attempts to initialize, a bus error occurs on the router. 

CR 112535: IP
           IP hosts on directly connected networks are unreachable from remote
           router slots.
