BGP route summarization configuration example
Network requirements
As shown in Figure 67, run EBGP between Router C and Router D, so the internal network and 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 Router A and Router B.
{ Configure OSPF between Router B and Router C.
{ Configure OSPF to redistribute static routes.
• 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 192.168.99.0/24 to Router D.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure static routing between Router A and Router B:
# Configure a default route with the next hop 192.168.212.1 on Router A.
<RouterA> system-view
[RouterA] ip route-static 0.0.0.0 0 192.168.212.1
# Configure static routes to 192.168.64.0/24, 192.168.74.0/24, and 192.168.99.0/24 with
the same next hop 192.168.212.161 on Router B.
<RouterB> system-view
[RouterB] ip route-static 192.168.64.0 24 192.168.212.161
[RouterB] ip route-static 192.168.74.0 24 192.168.212.161
[RouterB] ip route-static 192.168.99.0 24 192.168.212.161
3. Configure OSPF between Router B and Router C and configure OSPF on Router B to redistribute
static routes:
# Configure OSPF to advertise the local network and enable OSPF to redistribute static routes on
Router B.
