OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(28)S3
Further Problem Description: The symptom is very unlikely to occur. The symptom does not occur
on a router that has exclusively stub areas and NSSA areas. The symptom may occur when a router
does not have exclusively stub areas and NSSA areas.
• CSCef97738
Symptoms: BGP may pass an incorrect loopback address to a multicast distribution tree (MDT)
component for use as the source of an MDT tunnel.
Conditions: This symptom is observed when you reload a Cisco router that runs Cisco IOS
Release 12.0(28)S1 and when there is more than one source address that is used in BGP, such as Lo0
for IPv4 and Lo10 for VPN. If the IPv4 peer is the last entry in the configuration, the MDT tunnel
interface uses lo0 as the source address instead of lo10. The symptom may also occur in other
releases.
Workaround: Remove and add the MDT statement in the VRF.
• CSCeg19442
Symptoms: A router that is configured with the OSPF routing protocol may reload.
Conditions: This symptom is observed when the OSPF process is simultaneously deconfigured via
one session and configured via another session.
Workaround: There is no workaround. Cisco strongly discourages you to configure a router via two
different but simultaneous sessions.
• CSCeg70726
Symptoms: A router may crash when you enable MVPN by entering the mdt default group-address
command under a VRF.
Conditions: This symptom is observed on a Cisco router that is configured for BGP VPNv4.
Workaround: There is no workaround.
• CSCsa57101

to be filtered.
Conditions: This symptom is observed on a Cisco router that is configured for BGP and that
functions in an MPLS VPN environment.
Workaround: There is no workaround.
ISO CLNS

Workaround: Disabled IS-IS Incremental SPF.
