BGP Local router ID is 1.1.1.1

{ 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.
{ 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 S2/2/0, the other with next hop 3.1.2.1 and outbound
interface S2/2/1.
BGP route summarization configuration
Network requirements
As shown in Figure 76, run EBGP between Router C and Router D, so the internal network and 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.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure static routing between Router A and Router B:
