IP Routing Protocols
CSCef95026
Symptoms: When interfaces flap, a Cisco router may reload unexpectedly because of a bus error.
Conditions: This symptom is observed when OSPF accesses a freed LSDB entry.
Workaround: There is no workaround.
CSCeg07725
Symptoms: A router may continue to redistribute an eBGP route into EIGRP after the eBGP route
is deleted or EIGRP may not redistribute an eBGP route after the eBGP route has been installed.
Conditions: This symptom is observed on a Cisco router that redistributes eBGP routes into EIGRP
when the router functions in a multihoming environment.
The symptom occurs in a configuration with two PE routers that advertise routes via eBGP and a
border router that is configured with a higher local preference than the PE routers when the eBGP
route of the primary path is withdrawn and the route of the secondary path is installed.
Workaround: If a route is still redistributed into EIGRP after the eBGP route is deleted, clear the
BGP peer from which the eBGP route used to be learned so EIGRP stops advertising the route.
If a route is not redistributed into EIGRP after an eBGP route is installed, clear the route so EIGRP
starts advertising it. Another workaround is to enter the /jointfilesconvert/415844/bgp redistribute-internal command to
cause EIGRP to redistribute iBGP routes and to prevent EIGRP from failing to redistribute an
updated BGP route.
CSCeg54375
Symptoms: Routing inconsistencies may occur in the RIB: routes may be missing from the RIB but
may be present in the BGP table.
Conditions: This symptom is observed on a Cisco RPM-XF when the toaster processor crashes.
However, the symptom may occur on any platform that has a toaster processor.
Workaround: Enter the clear ip route vrf vrf-name * command.
CSCeg89700
Symptoms: A Cisco router does not recognize an end-of-RIB message from a third-party vendor
router and continues to show the “Neighbor is currently in NSF mode” message although the restart
procedure of the third-party vendor router is complete.
Conditions: This symptom is observed on a Cisco router that is configured for IPv6 BGP peering
and NSF. Note that the symptom does not occur when IPv4 BGP peering is configured.
Workaround: There is no workaround.
CSCeh16989
Symptoms: The Multiprotocol BGP (MP-BGP) network entries counter increases above the real
number of reachable networks.
Conditions: This symptom is observed when network activity occurs in a non-converged
environment. The correct number of network entries is restored when there is a period of BGP
stability that last for about 1 minute or more because BGP is able to converge and the scanner has
time to run and collect the old network entries. However, if there is a sustained period of churn and
BGP is only able to converge for a few seconds before new updates arrive, old BGP network entries
are not cleaned up, causing the MP-BGP network entries counter to increase above the real number
of reachable networks.
Workaround: There is no workaround.
