Was reading PfR on a cisco site, and it says:
In the current implementation of OER, external BGP or static routes can serve as parent routes with external interfaces being point-to-point or multipoint interfaces (Ethernet) with a single next hop. In other words, multipoint GRE interfaces (as with a DMVPN configuration) that has multiple next hops reachable from the mGRE interface are not supported. Additionally, Ethernet interfaces with multiple next hops, which is a common BGP peering deployment topology, is not currently supported.
Up to 10 border routers and a total of 20 external interfaces are supported per master controller.
We have WAN facing ethernet interfaces.
Is PfR going to work on these routers or no?
Our WAN interfaces are configured w/ a typical /30 mask, w/ one next hop towards the ISP.
So in theory that's considered single next hop, even though it's on a multi-access medium?
Also, the limit seems to be 10 BR's per MC.
Does that mean if we have 100 remote locations, each w/ two routers, we'd need to have a cluster of 20 (100*2/10)dedicated routers to serve as master controllers?
That doesn't seem very scalable to me.
Is anyone actually doing this on your production network?
How is it working for you?
