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

[Corbett Nelson (cornelso)]

Have you looked at the 12.3T train yet? A good amount of scalability and
feature enhancements (as well as bug fixes) were integrated into 12.3.

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,

Steve
