Symptoms: Cisco VPN Client 4.6.x connected to a Cisco IOS router configured as the VPN Server 
passes traffic correctly but after phase 2 SA rekeys, repeated phase 2 SA rekeying occurs and the 
Cisco VPN Client disconnects. The client log shows:

IKE/0xE3000099

Immature Navigation Termination due to error (Navigator:195)

The router debug shows:

IPSEC(update_key_lifetimes): volume lifetime reached 0, dropping SA sibling

Conditions: This symptom has been observed with Cisco VPN Client 4.6.x connected to a router 
configured as the VPN Server and running Cisco IOS Release 12.4(2)T.

Workaround: Downgrade the router to Cisco IOS Release 12.4(3).

Symptoms: BRI backhauling does not work on Cisco 2801 routers.

Conditions: This symptom has been seen on Cisco 2801 routers with Cisco IOS interim 
Release 12.4(02.02)T and Cisco IOS Release 12.4(2)T1. Backhauling works perfectly with 
Cisco IOS interim Release 12.4(1.9).

Workaround: There is no workaround. 

CSCei78836

Symptoms: When PPPoE L2TP sessions are brought up, a “Cannot insert into AVL tree” error 
message is generated for each session that is brought up.

Conditions: This symptom is observed only when a policy map is applied to the virtual template 
interface that is used for the sessions.

Workaround: There is no workaround. 

CSCei81698

Symptoms: When Cisco CallManager Express (CME) 3.4 interworks with Cisco Unity 4.1, Unity 
may send a Message Waiting Indication (MWI) notification to CME for extensions that are not 
configured on CME.

Conditions: This symptom is observed when you configure Cisco Unity 4.1 with some mailboxes 
and then reset Unity. (Doing so may cause CME to crash.)

Workaround: There is no workaround. 

CSCei83122

Symptoms: Although a Flexible Packet Matching (FPM) service policy can be applied to the host 
and transit control-plane configuration submodes, the FPM service policy does not apply the 
expected policy action (for example, a drop action) to matching packets because FPM functionality 
is not supported in the host and transit control-plane configuration submodes.
