Resolved Caveats—Cisco IOS Release 12.0(33)S10
All the caveats listed in this section are resolved in Cisco IOS Release 12.0(33)S10. This section
describes only severity 1, severity 2, and select severity 3 caveats.
• CSCed68723
Symptoms: Packets that are destined for an MPLS VPN may not reach their destination. The output
of the show ip cef vrf vrf-name detail command may show the following tag information:
10.0.0.0/16, version 437, epoch 0, cached adjacency to POS4/0
0 packets, 0 bytes
Flow: AS 0, mask 16
tag information set, all rewrites inherited <---------
local tag: assigned-when-resolved-later <---------
via 10.1.1.1, 0, 0 dependencies, recursive
next hop 10.2.2.2, POS4/0 via 10.1.1.1/32
valid cached adjacency
Conditions: This symptom is observed on a Cisco router that is configured for MPLS VPN
forwarding and CEF.
Workaround: Clear the affected route by entering the clear ip route vrf vrf-name network mask
command.
• CSCsa49922
Symptoms: When an EIGRP internal route goes down, it may remain in the routing table although
it is deleted from the EIGRP topology table.
Conditions: This symptom may occur when a router has an EIGRP internal route and an external
route as the Successor and the Feasible Successor, respectively, for the same network and then the
internal route goes down.
Workaround: Use either the internal route or the external route for the same network.
• CSCso88138
Symptoms: When there is a link flap or a reload, RSVP shows that the interface is down while
actually the interface is up. Because of this, the tunnel may take a backup path even when the
interface is up.
Conditions: Unknown at this time.
Workaround: Perform a shut/no shut on the interface.
• CSCsx08294
Symptoms: A Cisco 6500 running Cisco IOS Release 12.2(33)SXH may encounter a bus error due
to OSPF processes.
Conditions: Occurs when the device is configured for OSPF Incremental SPF and Virtual Links.
Workaround: Do not use Incremental SPF.
