Example: An aggregate address example is shown as follows.
As shown in Figure 96 , routers R1 and R2 separately advertise
routes 170.10.0.0/16 and 170.20.0.0/16. R3 aggregates the
information about the two routes into a route 170.0.0.0/8 and
advertises the route to R4. After aggregation configuration, the
routing table of R4 can only learn the aggregated route
170.0.0.0/8.
