I wanted to use 12.2(31)SB11, but a severe bug prevented me from doing so,
so I'm actually using 12.4(19b) and it's running just peachy. But I'm not
needing FR T-1's or VRF-lite.

Subject: [cisco-bba] Which IOS?



Hello,



I am wondering what IOS people are using or would recommend for the
following setup:



7206VXR NPE-G1, 1GB RAM, mix of PA-A3-T3 & PA-A6-T3 cards doing PPPoA and a
few FR T1's in a service provider environment. The biggest feature I need
is VRF-Lite, but thats pretty common? No MPLS etc (Though perhaps in the
future?).



I'm currently using the 12.2.(31)SB train, and with around 1500 active
sites.



Does that sound right, or is it time to move to a 12.4 mainline?



Thanks in advance

Dear dlists,

You should be running on 12.2(31)SB train, with a longer term migration path
to 12.2(33)SRC as these are SP oriented tracks.
12.4 is more enterprise oriented...

The bug (CSCsr57636) has to do with DHCP. We relay our DHCP requests to an
external DHCP server (i.e. we don't use Cisco's internal one) and that is
apparently a trigger for something.



This is what the engineer has shared:

In short, the particular process and the crash trace indicates the problem
occurs when the router is attempting to DHCP set peer address and the
problem was occurred in the IP address database. The issue appears on a rare
condition and which from research, no similar case has been discovered on
the field previously. At this stage I am also reviewing the case detail in
the original services request 609120131 regarding PPP to determine if the
crash would only occurs under such racing condition where the requests
coming in or at sessions churning.

Can you elaborate on the severe bug? I'm just upgraded to 12.2(31)SB13 a
couple days ago, no problems yet (knock on wood).

After several months of patience involving two early a.m. maintenance
windows and two test builds I'm now much closer to getting a catastrophic
bug affecting us in 12.2(31)SB11 resolved. From the crash dumps Cisco was
able to identify an issue with using an external DHCP server under high
usage loads (i.e. when downlink to all customers flaps). After a little
urging Cisco took the time to replicate the environment so that now they are
able reproduce the issue within 10 minutes.

we run MPLS with the G1, 1GB RAM, PA-A3-T3, PA-MC-TC and several
thousand PPP connections, full BGP tables etc. We use 12.4(19)T2. It's
been fairly solid (maybe 3 reloads in 2 years on 6 chassis), but is
definitely loaded with features we don't need.
