Basic PFR on a single router connected to Dual ISP with BGP.

Hi,

 

I have implemented PfR for one of my customers .The configuration is basic .

The two external interfaces are gig 0/0 and gig 0/2 connected to 2 different ISPs.

Xmit utilization is 50 % on both the interfaces. How ever if i initiate uploads to google drive and microsoft 's onedrive. The traffic for both flows through only one link gig 0/0 even though it reaches 80% , PfR does not move one of the traffic to gig 0/2. The rate of gig 0/2 is 0 bits/secs.

I see following in the logs:

Hi mate,

check this one out.

Your routing is most probably not complete.

Also, implementing the old OER most probably has no future. Check out the latest BRKRST-2362 session on Ciscolive365.com for PfRv3.
