We are implementing an MPLS network between the main offices in different countries and keeping the existing domestic WAN comprised of IPSec/GRE tunnels between the regional offices and main office with a country.
We're looking for a way that we can identify which offices/countries are using what amounts of bandwidth on the MPLS cloud.
I am attaching a diagram to help show what we are looking for. For example, we would want to know how much bandwidth was used by users in the UK when they access the Exchange servers in China or how much bandwidth the users in China are consuming when using the Oracle servers in NY.
We have a NAM blade in a 6513 core switch in New York which I believe we could make use of with netflow. Would we need some sort of netflow device in each country's main office so we can collect statistics from there?
[toc:faq]The ProblemOn traditional switches whenever we have a trunk
interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
[toc:faq]Introduction:Netdr is a tool available on a RSP720, Sup720 or
Sup32 that allows one to capture packets on the RP or SP inband. The
netdr command can be used to capture both Tx and Rx packets in the
software switching path. This is not a substitut...

in the network to know of every link and OSPF speaker in the entire
network. From this picture each router independently runs the Shortest
