Bgp Route Summarization Configuration Example - HPE 5800 Series Configuration Manual

# Display the BGP routing table on Switch A.
[SwitchA] display bgp routing-table
Total Number of Routes: 3
BGP Local router ID is 1.1.1.1
Status codes: * - valid, ^ - VPNv4 best, > - best, d - damped,
*> 8.1.1.0/24

The route 9.1.1.0/24 has two next hops, 3.1.1.1 and 3.1.2.1, both of which are marked with
a greater-than sign (>), indicating they are the best routes.
By using the display ip routing-table command, you can find two routes to 9.1.1.0/24: one
with next hop 3.1.1.1 and outbound interface VLAN-interface 200, the other with next hop
3.1.2.1 and outbound interface VLAN-interface 300.

BGP route summarization configuration example

Network requirements
As shown in
external network can communicate with each other.
In AS 65106, configure static routing between Switch A and Switch B, configure OSPF between
Switch B and Switch C, and configure OSPF to redistribute static routes, so the devices in the
internal network can communicate with each other.
Configure route summarization on Switch C so BGP advertises a summary route instead of the
specific networks 192.168.64.0/24, 192.168.74.0/24, and 192.168.99.0/24 to Switch D.
