OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
CSCee43166
Symptoms: The BGP inbound update processing becomes slow and a high CPU utilization occurs
for a long time.
Conditions: This symptom is observed when a large number of VRFs (more than 200) and prefixes
(more than 220,000) are configured.
Workaround: There is no workaround.
CSCee66936
Symptoms: A software-forced reload may occur on a router that is configured with a DVMRP
tunnel.
Conditions: This symptom is observed on a Cisco router when the DVMRP tunnel is brought up and
routing information is redistributed between DVMRP and MBGP.
Workaround: There is no workaround.
CSCee85676
Symptoms: When VPNv4 route advertisement are received after BGP has converged, the existing
path is updated but imported paths from the original path are not updated accordingly.
Conditions: This symptom is observed on a Cisco router that functions as a PE router when the
maximum-paths number-of-paths import number-of-paths command is enabled. The symptom
occurs when the path attributes are changed dynamically instead of the path being completely
withdrawn and readvertised.
Workaround: Withdraw the prefix from the remote PE router and then readvertise the prefix.
CSCee86530
Symptoms: A BGP update that is sent to a connected P router fails to report the martian next-hop
log message when the next-hop field in the attribute of the BGP update is set to 255.255.255.255
(that is, all 1ís). The P router does deny the advertisement of the MP_REACH_NLRI attribute to the
other PE routers, but there is no log message to indicate that it is denying the advertisement and why
it does so.
Conditions: This symptom is observed during MP-BGP negative testing for the MP_REACH
attribute.
Workaround: There is no workaround.
CSCee88542
Symptoms: A Cisco router may reload unexpectedly when you enter the show ip msdp peer
command.
Conditions: This symptom is observed when the MSDP session flaps while you enter the show ip
msdp peer command.
Workaround: There is no workaround.
CSCee89438
Symptoms: An MSDP enabled RP does not build an (S,G) state from its SA cache when it should
do so. Depending on the topology and if an SPT threshold is configured as infinite, this situation
may result in a multicast forwarding interruption of up to 2 minutes.
Conditions: This symptom is observed when the RP for a group fails and an incoming (*,G) join
message is received.
MSDP should create an (S,G) state from its SA cache. However, this is done before the (*,G) olist
is populated; because of the (*,G) NULL olist, MSDP does not install an (S,G) state.
