We have one HK customer who interested in Extreme SDN Product. They’re asking how to migrate to SDN from their existing network. Is it possible to run the existing network (L3 routing is OSPF) and SDN concurrently in their existing core (BD8K) and distribution switch (X460)? For example, OSPF routing and SDN Controls run in one box concurrently. If so, how to control the forwarding path in the core and distribution switch.
As I cannot find any reference SDN document mentioning this strategy. Would you pls help? Thanks.
