Bgp Route Summarization Configuration - HPE FlexNetwork HSR6800 Configuration Manual

*> 9.1.1.0/24
*
The output shows two valid routes to destination 9.1.1.0/24: the route with next hop 3.1.1.1 is marked with
a greater-than sign (>), indicating it is the best route; the route with next hop 3.1.2.1 is marked with only an
asterisk (*), indicating it is a valid route, but not the best.
By using the display ip routing-table command, you can find only one route to 9.1.1.0/24 with next hop
3.1.1.1 and outbound interface S2/2/0.
Configure load balancing:
3.
Because Router A has two routes to reach AS 65009, configuring load balancing over the two
BGP routes on Router A can improve link utilization.
# Configure Router A.
[RouterA] bgp 65008
[RouterA-bgp] balance 2
[RouterA-bgp] quit
Verify the configuration:
4.
# Display the BGP routing table on Router A.
[RouterA] display bgp routing-table

BGP Local router ID is 1.1.1.1
Status codes: * - valid, ^ - VPNv4 best, > - best, d - damped,

The output shows two valid routes to the destination 9.1.1.0/24, and both of them are marked with a
greater-than sign (>), indicating they are the best routes.

BGP route summarization configuration

Network requirements
As shown in
external network can communicate with each other.
In AS 65106, configure static routing between Router A and Router B, configure OSPF between
Router B and Router C, and configure OSPF to redistribute static routes, so devices in the internal
network can communicate with each other.
Configure route summarization on Router C so BGP advertises a summary route instead of the
specific networks 192.168.64.0/24, 192.168.74.0/24, and 192.168.99.0/18 to Router D.
