I have recently configured PfR on our routers (Two routers) one as a MC and BR with 200 mbps internet connection directly conenctioned to MPLS and the other as a BR with 100 mbps internet connection directly connected to MPLS and change the aggrigation type to BGP and mode route is set to be on observe with below configuration,
The main purpose here by deploying PfR is to use PfR magic to have a redundent path/connection so if traffic on the 1st router hit the 75% of BW utilization treshhold, the rest of the traffic (25%) would get re-routed to the 2nd router (100 mbps ).
I have been monitoring it for last few days but it doesnt seem to be working fine becaouse the trfaic on the primary router hitting almost 95 percent of its BW and nothing is being re-routed to the backup router!
All configuration looks to be fine and the connection status is success on both MC and BRs...
I am currently using PfR v. 3.3 on primary router and v.3.0 on back up router.
We are redistributing bgp to eigrp and eigrp to bgp using route-maps.
I wonder if anyone could provide some feedback so that i could fix and troubleshoot this issue and make it work.
