Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(27)S4
Workaround: Enter the mpls traffic-eng tunnels interface configuration command on the outbound
interface of the Cisco router. Then, enter the shutdown interface configuration command followed
by the no shutdown interface configuration command on this interface, and save the configuration.
• CSCef92863
Symptoms: A Cisco 10000 PRE-1 may reload when a VRF that is configured with eight maximum
paths is modified.
Conditions: This symptom is observed when a VRF on the Cisco 10000 series is configured for eight
maximum EIBGP paths by entering the maximum-paths eibgp 8 command and when the VRF is
modified in such a way that there is a change in the number of paths that are available. The symptom
may also occur on a Cisco 10720.
Workaround: A Cisco 10000 series can support only six maximum paths. Therefore, configure the
number of maximum paths by entering the maximum-paths eibgp 6 command.
ISO CLNS
• CSCeg00610
Symptoms: A router running Cisco IOS software may reload unexpectedly.
Conditions: This symptom has occurred when running those versions of software with the Integrated
Intermediate System-to-Intermediate System (IS-IS) Incremental shortest path first (SPF) feature
and when IS-IS Incremental SPF feature is enabled to run.
Workaround: Disabled IS-IS Incremental SPF.
Miscellaneous
• CSCed16318
Symptoms: When changing the MTU on an Engine 2 3-port 1GE line card, the line card may reload.
Conditions: This symptom is observed on a Cisco 12416 router that is running the gsr-p-mz image
of Cisco IOS Release 12.0(26)S.
Workaround: Ensure there is no traffic going through the Engine 2 3-port 1GE line card when
attempting to change the MTU.
• CSCed57204
Symptoms: When a large number of VRFs are configured, input OAM F5 loopback cells on the ATM
interface are dropped continuously even without traffic. Drop could be seen at OAM cell drops of
show atm traffic and at Input queue drops of show interface ATM EXEC commands.
Conditions: This symptom is observed on a Cisco 7500 series router that is running Cisco IOS
Release 12.2(19), Release 12.3(5), or Release 12.3(4)T2 where the oam-pvc manage command and
the ip vrf global command are configured.
Workaround: Remove the ip vrf command. There is no workaround for a router such as a provider
edge (PE) router that cannot remove VRFs.
• CSCed81317
Symptoms: With the import map configured on the VPN Routing and Forwarding (VRF), even the
CE-learned routes (non-eBGP) are getting filtered out so they will never appear in the VRF routing
table.
Conditions: Under VRF configuration, import map word needs to be configured. Due to the
symptom, this filter is applied to CE-learned routes with the exception of eBGP routes.
