How to deaggregate a route ? i.e let us suppose we have the following topology, R1--R2--R3. R1 has the following networks 192.168.1.0/24, 192.168.2.0/24 and 192.168.3.0/24, so R1 aggregates the prefixes into 192.168.0.0/22 and advertise it to R2. Now let us suppose that R2 wants to deaggregate this route and advertise to R3 only the more specific prefix 192.168.1.0/24. Any help about the Deaggregation command lines would be appreciated.
