Symptoms: The withdraw message of a multipath (not bestpath) from a BGP neighbor deletes the
path from the BGP table but it does not uninstall the route from the IP routing table.

Symptoms: A router may crash after the IP address of the interface of a neighboring router is
changed while an MPLS TE tunnel is using this interface.
changed while an MPLS TE tunnel is using this interface.
Conditions: This symptom is observed on a Cisco router that functions as a midpoint of an MPLS
traffic engineering (TE) tunnel and occurs shortly after the IP address of the ingress interface of the
downstream neighboring router is changed while the MPLS TE tunnel is using this interface.

CSCed62901
Symptoms: This symptom occurs in an OSPF network topology in which a CE router (CE-1) connect
to a PE router (PE-1) that connects to two other PE routers (PE- 2 and PE-3), each of which connect
to another CE router (CE-2 and CE-3). In turn, both of these CE routers are connected to each other
(that is, CE-2 and CE-3 connect to each other).

to another CE router (CE-2 and CE-3). In turn, both of these CE routers are connected to each other
(that is, CE-2 and CE-3 connect to each other).
When the link between the PE-3 and the CE-3 flaps, the OSPF route in the VRF fails to switch back
from BGP to OSPF on the PE-1.
from BGP to OSPF on the PE-1.
Conditions: This symptom is observed in Cisco IOS Release 12.0 S, 12.2 S, and 12.3 T.
Workaround: Clear the ip route, clear the OSPF process, or enter the clear ip bgp * command on
the PE-1 to bring the route back from BGP to OSPF.

Conditions: This symptom is observed when the router is configured for OSPF and is actively
learning OSPF routes dynamically.
