[ovs-discuss] Network Aggregation in OpenFlow Networks

[Syed Amir Shahzad]

How controller can aggregate the networks efficiently by avoiding black hole for example we have following prefixes
10.0.0.0/24
10.0.1.0/24
10.0.2.0/24
10.0.7.0/24

if controller sends summary as 10.0.0.0/21 it will include extra network that we don't  have in  table like 10.0.3.0/24, 10.0.4.0/24, 10.0.5.0/24 and 10.0.6.0/24. thats creates black-hole. How we can handle this in OpenFlow Controller???
