Hi all,
Imagine you have a number of GE and 10GE interfaces spread across =
multiple MX-class Juniper routers, and for each interface you want to =
maintain an accurate count of bytes sent, categorised by destination =
address.
There is no layer-2 aggregation going on beyond the router, so no =
opportunity to create span ports on which to measure over on the side.
Using optical splitters on each and every router interface and listening =
on the side using dedicated sniffers is an option, although it means =
tangles of fibre and potentially lots of sniffer boxes with lots of =
interfaces.
I don't necessarily need a free or tremendously cheap solution, although =
it's always nice not to have to spend money.
What are better approaches?
Off-list would be fine if people have experience of this kind of thing; =
I can summarise if there is interest.
