[nsp] NPE-G1 LNS / VRF dropped packets problem

[Paul Grehan]

Hi Steve,

We had a similar issue related to CEF for 12.2.15T5 on an NPE-400...

12.3.6 Enterprise seemed to fix it....there was an inconsistency with
allocation of CEF switching for pre-cloned interfaces...

-> Hi All,
-> 
-> Is anybody running 7200 NPEG1s for ADSL LNS boxes, 
-> specifically where you are terminating PPP sessions into a 
-> VRF ? IE the vpdn group uses a virtual-template that is set 
-> to drop sessions into a named VRF ?
-> 
-> We have some problems with a tiny handful of users sessions 
-> where traffic between ADSL CPE (that never leaves the LNS to 
-> the next hop) are dropping packets, also traffic between the 
-> CPE and LNS are dropping packets. Whereas traffic from a 
-> next hop router (further upstream from the LNS) to CPE is 
-> never dropped ?
-> 
-> This behaviour appears to be intermittant, and it smells of 
-> CEF forwarding problems relating to the use of VRFs.... It 
-> does not appear to be congestion within the ATM/l2tp cloud.
-> 
-> I've got a TAC case open (no response as yet).
-> 
-> We're running 12.2(15)T12 (enterprise release)
-> 
-> Thanks,
