Hi All,
I can't seem to get enough of OER and PfR at the moment and after
completing all my lab exercises I decided to deploy OER configuration on
a 1800 router connected to the Internet with a single connection to
monitor the traffic and get a feel for real traffic patterns.
Performance Routing is designed for multihoming, which requires a
minimum of two external interfaces. However, Performance Routing can be
configured to monitor application performance over a single interface by
creating a second dummy interface, which will not forward packets. Use a
Dialer interface for the second interface but do not attach any physical
interfaces to the Dialer. The Dialer interface needs an IP address
because Performance Routing checks that the interfaces are routable. The
IP address assigned to the Dialer does not need to be advertised. My
dummy interface is Dialer2.
Each learned list can be displayed individually with the command: "show
oer master traffic-class learned list NAME" or for all lists: "show oer
master learn list".
The following shows my configuration:
