After the above configurations, ping the hosts on networks 192.168.64.0/24,
192.168.74.0/24, and 192.168.99.0/24 from Router D. The ping operations succeed.
5. Configure route summarization on Router C:
# Summarize 192.168.64.0/24, 192.168.74.0/24, and 192.168.99.0/24 into a single route
192.168.64.0/18 on Router C and disable advertisement of the specific routes.
[RouterC-bgp] aggregate 192.168.64.0 18 detail-suppressed
[RouterC-bgp] quit
