Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(31)S5
CSCsc73598
Symptoms: The IGP metric is not updated to an eBGP peer when there is an IGP- metric change.
The BGP peer is not advertising this change after its default timer of 10 minutes.
Conditions: This symptom occurs when a link goes down and the IGP metric to reach the BGP
nexthop has changed. When used in a route-map, the set metric-type internal value should
propagate any MED changes in updates to the BGP peers.
Workaround: Use clear ip /jointfilesconvert/415844/bgp neighbor-address [soft [in | out]] on the respective router to get the
correct metric changes and BGP best path.
CSCsc74229
Symptoms: A router may delete the VPNv4 prefixes from the BGP table, even though the counters
in the output of the show ip /jointfilesconvert/415844/bgp command may indicate that the VPNv4 prefixes are present in the
BGP table. This situation may cause loss of VPN connectivity.
Conditions: This symptom is observed on a Cisco router that is configured for MPLS VPN and that
functions as a PE router.
Workaround: There is no workaround. When the symptom occurs, enter the clear ip /jointfilesconvert/415844/bgp * command
to restore proper operation of the router.
Miscellaneous
CSCef35269
Symptoms: A Cisco 7500 series that has a multichannel E1 port adapter that is configured with PPP
multilink groups on several E1 channels may drop packets:
When dCEF is enabled, packets that are larger than 1492 bytes are dropped. Note that this
particular symptom is addressed and fixed via CSCin73658.
When the router has dCEF disabled, packets that are larger than 1500 bytes are dropped.
Conditions The symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.0(28)S.
Workaround: Configure only one interface as the member of the PPP multilink group. Note that the
symptom does not occur in Release 12.0(26)S3, 12.0(27)S2, and 12.1(19)E1.
CSCef82084
Symptoms: Spurious memory accesses occur on a Cisco 7200 series and ALIGN-3-SPURIOUS
error messages are generated.
Conditions: This symptom is observed when there is traffic through the serial interface.
Workaround: There is no workaround.
CSCeh31441
Symptoms: A linecard reloads when traffic is sent through an ATM PVC with the QoS policy
enabled.
Conditions: The symptom occurs only with the following configuration.
policy-map foo
class class-default
shape average <cir>
interface atm1/0/0.
pvc <vpi>/<vci>
