Caveats for Cisco IOS Release 12.0

Resolved Caveats—Cisco IOS Release 12.0(13)

• CSCdr73314

A Cisco router that is running Open Shortest Path First (OSPF) on Cisco IOS Release 12.0(11) does

not populate the routing table properly. When redundant paths exist, half of the paths are missing

from the routing table. However, the missing networks appear in the OSPF database.

Workaround: Run a full shortest path first (SPF) by doing clear ip route * EXEC command.

• CSCdr76801

An Address Resolution Protocol (ARP) alias configuration is lost after a Cisco router reloads or

after you use the no shut command on an interface.

Workaround: Explicitly reconfigure the arp-alias entries for the IP addresses of the interface after

using the no shut command.

• CSCds04548

Open Shortest Path First (OSPF) does not work on unnumbered interfaces.

Workaround:Enter the ip address interface configuration command.

ISO CLNS

• CSCdr59905

A Cisco router that is running Connectionless Network Service (CLNS) and is redistributing

ISO-IGRP (Interior Gateway Routing Protocol) into ISIS might reload if a neighboring ISO-IGRP

router sends it a routing update that contains a default prefix router if the prefix route whose

next-hop is through “default” is then used for routing packets. There is no workaround.

Miscellaneous

• CSCdp05541

A system reloads when a crypto map is deleted for a subinterface. There is no workaround.

• CSCdp37597

A Cisco 7500 series Route Switch Processor (RSP) that is running Cisco IOS image

rsp-jsv-mz.112-18 might reload with a segV exception error while performing encryption

processing. There is no workaround.

• CSCdp52635

Voice calls on an AS5300 running with a mix of Regular PRI and NFAS Configuration might fail

on dial-peers matching the NFAS Trunks. There is no workaround.

• CSCdp85437

Routers using Cisco Encryption Technology (CET) may not be able to set up encrypted connections

in networks with redundant links between encrypting peers. This may result in crashing the router.

There is no workaround.

• CSCdp93988

A Cisco 7200 series router might reload because of memory corruption and exhibit the following

error message:

%SYS-2-MALLOCFAIL: Memory allocation of 520 bytes failed fr om 0x60395028, pool

Processor, alignment 0 -Process= "Pool Manager", ipl= 4, pid= 4 -Traceback= 603C84DC
