Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: Occurs when two bidirecitonal-enabled routers are servicing the last-hop receivers on
10 or more VLANs. There should be receivers on all 10 VLANs for a minimum of 1,000 groups.
When the Reverse Path Forwarding (RPF) link of active designated forwarder (DF) is shut or when
the link is brought back up, DF on the receiver VLAN needs to change from one box to another box.
During DF-transition, the DF-election flaps and multicast packets are looped up to 20 seconds.
Workaround: Configure the mls ip multicast Stub command on the receiver VLANs on both boxes.
• CSCsc94969
Symptoms: After configuring import ipv4 unicast map #name under ip vrf #name, all existing
routes (except direct connected) under the VPN routing/forwarding (VRF) table disappear.
Conditions: Occurs when router is configured with MPLS, VRF, and import IPv4.
Workaround: There is no workaround.
• CSCsd04608
Symptoms: When removing policy from interface, the router crashes.
Conditions: Occurs when policy is hierarchical with child and grandchild policy.
Workaround: There is no workaround.
• CSCsd61498
Symptoms: The BGP bulk-synchronizes even in RPR+ mode. When the standby RP is reset, the BGP
bulk-synchronization process ignores the notification and continues to bulk-synchronize.
Condition: The symptoms are observed when the standby RP is reset or when the router is in RPR+
mode.
Workaround: There is no workaround.
• CSCsd80349
Symptoms: In a MPLS Traffic Engineering Fast Reroute environment, if the line protocol on the
protected link goes down due to mismatched keep-alives on the link (or too many collisions), the
forwarding plane does not switch traffic for protected label switched paths (LSP) to their respective
backups.
Conditions: Occur under the following scenario:
–
A Cisco router running a Cisco IOS Release 12.2S
–
Router acting as a Point of Local Repair (PLR) for MPLS Traffic Engineering Tunnels that
request Fast Reroute protection
–
Mismatched keep-alives or excessive collisions on the protected link.
Workaround: There is no workaround.
• CSCsd82457
Symptoms: The EapOverUDP protocol cannot detect Cisco IP conference stations and wireless
phones, resulting in the policy configured locally on the box for IP phones not being applied.
Conditions: This symptom is observed with a normal EapOverUDP configuration that is used for
applying the NAC policies for IP phones.
Workaround: There is no workaround.
• CSCsd93294
Symptoms: On a CSC-PE router with dual RPs, the following is seen on the standby RP:
1. A near endless amount (about 45-50) of the following error messages:
