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>
