Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S
– A VRF OSPF process is parsed, but no router ID is available for the process.
Workaround: There is no workaround.
• CSCec33773
Symptoms: When a path is added to or deleted from the transit area between two virtual link routers
that function as virtual link endpoints, the routes that are learned from the network backbone may
not be updated in the routing table.
Conditions: This symptom is observed when there are multiple equal-cost paths for virtual links in
the transit area.
Workaround: After the path in transit area has changed, enter the clear ipv6 ospf force-spf
privileged EXEC command on the virtual link router that functions as a virtual link endpoint and
that is not part of the network backbone.
• CSCec40377
Symptoms: A multicast router may stop sending Protocol Independent Multicast (PIM) join
messages.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0(22)S,
Release 12.0(22)SY, Release 12.1(13)E, or Release 12.2(14)S and that is configured for multicast
routing when buffer allocation failures occur and when the I/O memory is low.
Workaround: Disable and reenable multicast routing.
• CSCec40548
Symptoms: A router may no longer be able to reach IP destinations through Open Shortest Path First
(OSPF).
Conditions: This symptom is observed when the mpls traffic-eng area number router configuration
command is removed from the OSPF configuration.
Workaround: Clear the OSPF process by entering the clear ip ospf process privileged EXEC and
wait for the OSPF process to recover. This workaround is not recommended when there is a large
routing table.
Alternate Workaround: Reconfigure the mpls traffic-eng area number router configuration.
• CSCec43805
Symptoms: The distance bgp external-distance internal-distance local-distance address family or
router configuration command may be missing from a Border Gateway Protocol (BGP) IPv4 Virtual
Private Network (VPN) configuration in the output of the show running-config privileged EXEC
command when all of the following keywords in the address-family ipv4 vrf vrf-name router
configuration command are configured with their default values:
- aggregate-address Configure BGP aggregate entries
- auto-summary Enable automatic network number summarization
- bgp BGP specific commands
- default Set a command to its defaults
- default-information Control distribution of default information
- default-metric Set metric of redistributed routes
- distance Define an administrative distance
- distribute-list Filter networks in routing updates
- exit-address-family Exit from Address Family configuration mode
- help Description of the interactive help system
- maximum-paths Forward packets over multiple paths
