we have two Internet circuits from two different ISPs. But inbalance of inbound traffic load balancing has been happening between the two circuits.
The circuit from ISP-A is fully utilized at around 80%, while the other from ISP-B is at around less than 20%.
We want to try to equalize the two circuit utilization for inbound traffic as much as possible. And I think PfR might work.
But since this is the 1st consideration of PfR for me, I’d wanted to help from you guys , so every thing can go smooth, most important , devices are in production.so applying any policy or changes would be on consideration.
Now my questions are:
is ISP would play the most important role , or it can be done only through ISP only, they need to advertise these Ip's for inbound traffic load balancing.
- Does our design work to mitigate our issue? I am planning to use “PfR - Inbound Load Balancing” referring to the below links. My concern is that our local global subnet to be advertized to eBGP is only one(202.xx.xx.x/24) so prepending AS number might/might not work.
- i am referring these documents.

- Is our design fine for PfR in the point of adding one MC and only running EIGRP to have reachability to L3SW and Internet routers?
- Our routers have only IPBase feature. Do we need DATA license for all three routers (current Internet routers Model: Cisco 3925 )
- What happens if primary router is stuck due to any reason(such as lack of CPU/Memory resource)?
The prefix controlled by PfR is just controlled by normal routing?
