BGP route summarization configuration example

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

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure static routing between Switch A and Switch B:
# Configure a default route with the next hop 192.168.212.1 on Switch A.
<SwitchA> system-view
[SwitchA] ip route-static 0.0.0.0 0 192.168.212.1
