Hi all.
We are lab'ing 12.2(33)SRC on an NPE-G2.
We see the VPNv4 AFI configuration saving a duplicate
configuration for a peer policy template inheritance:

Hey,
Sorry guys, I have one last CSM query which relates directly to the below.
In the customers network 1 of the 2 VIP's is actually used for server to
server load balancing.
So to simplify 3 servers all reside in the same subnet.
The addresses are the following:
server A: 10.20.220.11
Ross,
The only issue I see with using different VIP addresses has to do with
pushing the traffic to the CSM, which can be solved by different routing
mechanisms. The routing tweaks are sometimes not elegant, but are not
much different in a case where you use an external load balancer
(especially
Brad,
There is an alternative for client nat, which is usually not recommended
as it makes reporting and other mechanisms which rely on the source IP
to be unique.
The idea is to configure the VIP address (50.40.220.100) as a loopback
on the real servers. Then, disable nat server on the

Hi Brad,
Thanks for the response. I saw those drops, but they don't come close to the
amount of times this is occurring. This happens literally, every 34 minutes
(okay, 33 minutes and some seconds :-) ):

OK,
Just how much BGP should a 7200vxr-NPE400 with 512MB of RAM be able to
handle.
Presently:

Does a sh standby 1 show any hsrp state changes? might also be worth
setting up an ip sla probe to your neighbor for the 34 minutes to
probe every second and just see if it fails at all when you lose your
OSPF neighbor, that way you can discard OSPF from the problem and look
into what is

With a Sup32, the line run on a 16 Gbps shared bus. (No, it's

IOS XE *is* IOS. It 'just' runs on another kernel.

Definitely. Since it happens fairly predictably, you should also be
able to set the load-interval to 30 on the interfaces connecting to
those neighbours and check if there's a momentary increase of traffic
on those interfaces
From what I recall, OSPF does a periodic sanity check every 30 minutes where
it flushes its SPF table or something like that. Could this timing be related
to something during that process? Wild guess, but I have seen issues with
bouncing EIGRP adjacencies that were related to MTU sizes being
