Release Notes for Cisco IOS Release 12.0 S
78-7130-11 Rev. B0
Caveats
Interfaces and Bridging
• CSCdm19573
A Cisco 7200 series router that is running Cisco IOS Release 11.1(22)CC or Cisco IOS
Release 11.1(25)CC with a PA-CT3 might experience problems with local-area transport (LAT)
services under the following conditions:
If you are using transparent bridging with LAT enabled on a serial interface, you might not see LAT
services when entering the show lat service command, even when the remote link (also using
transparent bridging with LAT enabled) is advertising LAT services. There is no workaround.
• CSCdp18313
A Cisco 7206VXR router that is running Cisco IOS Release 12.0(6.5)T2 and has a network
processing engine (NPE)-300 network processing engine might reload with a bus error. There is no
workaround.
IP Routing Protocols
• CSCdp26552
Open Shortest Path First (OSPF) and summary link-state advertisement (LSA) is not installed in
the routing table.
Workaround: Clear the routing table and restart the OSPF process.
• CSCdp30454
The dataless header register is not working properly in Cisco IOS Release 12.0(7)S. There is no
workaround.
• CSCdp39843
If a Cisco router receives a Resource Reservation Protocol Reserve (RESV) message to refresh a
label-switched path (LSP) for which it is the source, and if the RESV message contains a
Multiprotocol Label Switching (MPLS) label other than the one previously received, the router will
attempt to perform a label change operation. If the label change operation fails, the router might
reload while executing the appropriate error handling procedures. This situation rarely occurs.
There is no workaround.
• CSCdp57762
A Cisco router that is running Cisco IOS Release 12.0(05.06)S03 or later releases up to Cisco IOS
Release 12.0(8.5)S might not send withdraw requests and not delete the entry from the IP routing
table under the following *SOFT RESET* conditions:
– The neighbor soft-reconfiguration router configuration command is entered on the router for
a particular peer.
– The route-map global configuration command is entered to modify attributes.
– There is a used entry and a received-only entry for a given prefix, and the neighbor filter-list,
neighbor distribute-list, or neighbor prefix-list router configuration commands or the
route-map global configuration command is entered to deny this prefix.
– The soft clear bgp EXEC command is entered.
Symptoms of this situation include the prefix being present in the Border Gateway Protocol (BGP)
table with the received-only path, the prefix remaining in the IP table, and the prefix not being
withdrawn from all the other peers to which it has advertised. These symptoms do not occur if both
