Bgp Load Balancing Configuration Example - HP 6125XLG Layer 3 - Ip Routing Configuration Manual

BGP Routing table Status : <Inactive>
Summary Count : 0
The output shows that Switch D has learned routes to 192.168.64.0/24, 192.168.74.0/24, and
192.168.99.0/24 through BGP.
After the above configurations, ping hosts on networks 192.168.74.0/24, 192.168.99.0/24,
and 192.168.64.0/18 from Switch D. The ping operations succeed.
5. Configure route summarization on Switch C to 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 Switch C,
and disable advertisement of the specific routes.
