I wish to know if their are solutions that could enable WAN Edge routers make routing decisions based on other factors like latency, delay, jitter e.t.c apart from prefix availability (availability of network).
Optimized Edge Routing (OER) / Performance Routing were suggested by some of my colleagues but after looking at those solutions they kinda do not meet my requirements. which include:
1) My client has close to 700 tunnels interfaces to the branch offices and OER/PfR can support a max. of 20 interfaces per Master Controller.
2)My clients have EIGRP as the IGP between the HQ and Branch Offices, on GRE tunnel interface over their ISPs but OER/PfR deployment are limited to BGP or statics at the WAN Edge.
Is there any other solution that factors IGPs like OER/Pfr
