Hello Nadeem,

>> How is RITE different from NetFlow?

Netflow classifies flows and exports information on observed flows, RITE attempts to export captured data (packets)

Depending on your needs netflow can be enough.

Also if you look at

http://www.cisco.com/en/US/partner/docs/ios/12_4t/12_4t11/ht_rawip.html

or

http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/ht_rawip.html

you can see the following limitations:

RITE export is done at L2 level the destination is actually a MAC address of a device in the same IP subnet of the exporting interface.

the document says RITE is supported only on ISR routers, C7200 is not mentioned

So RITE can be useful as an OSI L2 converter:

to capture data on a serial interface for example and to send them to a laptop with a protocol analyzer running on it.

Netflow export is IP based and can be sent to a collector server that is several hops away.

Even if C7200 supports it the cpu load for capturing traffic on an Oc-3 link can be high, there is an option to use ACLs to make a selective capture.

Hope to help
