The preceding command output shows that the next hop IP address (10.1.2.1) of the route
3.3.3.9/32 is not in the IP routing table, which indicates that the route is not selected due to the
unreachable next hop IP address. The following solutions can address this issue:

In this example, the network 10.1.2.0 30 command is configured on Router B. After the
command is configured, check the BGP routing table of Router A.

Configure a static route destined for 10.1.2.1/30 on Router A.
Configure an IGP on Router B and Router C and configure BGP to import the route 10.1.2.1
on Router B. This solution is not applicable to this specific scenario because Router B and
Router C are located in different ASs.
Run the import-route direct command on Router B. This solution is not optimal because
unnecessary routes may be imported.
Run the network 10.1.2.0 30 command on Router B to advertise the route 10.1.2.0/30 to
Router A.
Run the peer 10.1.1.1 next-hop-local command on Router B to configure Router B to
modify the Next_Hop of the route 3.3.3.9/32 before advertising the route to Router A.
