Command
ZXR10(config-router)#
><net-mask>[count <count>][as-set][summary-onl
y][strict]
Example
aggregate-address <ip-address
R1 and R2 advertise routes 170.20.0.0/16 and 170.10.0.0/16 re-
spectively.
R3 aggregates the two routes into 170.0.0.0/8 and advertises it to
R4. After route aggregate is configured, R4's routing table can only
learn the aggregate route 170.0.0.0/8. This is shown in Figure 3.
