PfR version 3 Performance Routing - can it be run at one site on one router ?

[hmcandrew]

I have a customer that is interested in load balancing and fail-over at one of their remote offices.

Right now, it appears that PfR will allow for this, all in one router.

The question is:  Does the router on the other end also have to be configured as such?

The customer has two Ethernet connections -- one is Internet VPN, the other is a private Ethernet hand-off.

Thank you.

Another question is -- can we even run PfR over Ethernet connections ?

While I can't answer your main question and might be able to address your real task of implementing load balancing and failover for a branch office.  \

If you run PfR on only on the branch router then you'd only get the benefits on the branch to HQ traffic.  HQ to branch traffic would use normal routing.  

Static routes and dynamic routing protocols (ospf/eigrp) will do load sharing and failover and might be more simple for your case.  

Most simple: 2 default routes with the same Administrative distances will be quick, easy and might fit in the "good enough" category.  

Better: ospf/eigrp neighbors between the HQ and branch router, making the branch a stub.  The protocols will do equal cost load balancing and failover probably right out of the box.

To answer your questions though...

Yes, you can do PfR on one router.

Yes, PfR works with etherent interfaces.

Here is a good post to read and learn about PfR.
