Configuration PFR for Internet Load Sharing

Hello Everybody

I´m a new fan of the PFR technologie, i´m some difficultie for set the learning mode.

Here is the scenario,

i have one 2 routers connecting to 4 ISP, each border router have 2 ISP or 2 External link

So my goal is to set a kind of load sharing for some application,

I need for example for my Http traffic to  be performed based on the best  External link

So i have this configuration on my PFR Master, but i´m not able to looking the Sh pfr master, the learn list doesn´t match anything

pfr master

Configuration PFR for Internet Load Sharing

Hi Junior,

An access-list under a pfr learn list is used to define the application signature rather than filtering . Applications can be identified either using port, protocol, dscp or any combination of it.we use the ACL to match the type of traffic and a prefix-list to match the destination prefix.

Refer : http://aitaseller.wordpress.com/2012/10/15/pfr-cisco-performance-routing/

Regards,

Sathvik
