Hi Brian,

You need to start a separate sflowtool process to handle the fan-out, then
set up two sflow consumers like this:

>        sflowtool_opts = -4 -p 5500 -l
>        sflowtool_bgp_opts = -4 -p 5501 -l

This means you'll end up with three sflowtool processes running:

- one to handle the fanout (-4 -p 6343 -f 127.0.0.1/5500 -f 127.0.0.1/5501)
- one consumer for rrd (-4 -p 5500 -l)
- one consumer for bgp (-4 -p 5501 -l)

This is what "ps ax|grep sflowtool" looks like on our sflow box:

>  594  -  S      27:48.20 /usr/local/bin/sflowtool -4 -p 6343 -f 127.0.0.1/5500 -f 127.0.0.1/5501
