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

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.
