Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S2
• CSCee42285
Symptoms: Non-EIGRP originated routes are not supported. Furthermore, when a route is injected
into mp-BGP from a connected, static, or any other IGP on the remote PE router where the same
prefix is also learned via EIGRP (when a backdoor exists for that site), the route may constantly flap
between EIGRP and BGP.
Conditions: These symptoms are observed when the EIGRP MPLS VPN PE-CE SoO feature is
configured.
Workaround: Only inject EIGRP routes into mp-BGP for sites with a backdoor.
ISO CLNS
• CSCed40888
Symptoms: A Border Gateway Protocol (BGP) session may be terminated unexpectedly.
Conditions: This symptom is observed on a Cisco router that functions as a peer in a BGP
configuration when you disable and reenter the neighbor ip-address send-label address family
configuration or router configuration command or when you move the router that has the neighbor
ip-address send-label address family configuration or router configuration command enabled to a
peer group.
Workaround: There is no workaround.
• CSCee54672
Symptoms: The redistribution of routes from L1 into L2 or/and from L2 into L1 may not occur
properly, and a learned IS-IS prefix may be missing.
Conditions: This symptom is observed under the following conditions:
– There are multiple paths to reach the same prefixes.
– One source LSP removes a prefix and another LSP adds the same prefix, while both paths
between the prefix and the LSPs are of equal cost.
Workaround: Enter the clear isis * or the clear ip route * command to restore the prefix. However,
doing so clears all the routes and recalculates them again, which is a disruptive action.
Miscellaneous
• CSCdy40928
Symptoms: Connectivity difficulties may occur when Virtual Private Network (VPN)
routing/forwarding (VRF) packets follow the global routing table instead of the VRF table.
Conditions: This symptom is observed on a low-end Cisco router that runs Cisco IOS
Release 12.2(7a) or another release when the global address space in the router overlaps with the
VRF address that is configured on a VRF interface of a connected PE router. The VRF interface of
this PE router may be unreachable but end-to-end connectivity may not be affected.
Workaround: There is no workaround.
• CSCea28043
Symptoms: IP commands that are sent in the Cisco Networking Services (CNS) config-changed
event output may contain an extra ip prefix.
