Refer to the exhibit. R1 is not learning about the 172.16.10.0 subnet from the BGP neighbor R2 (209.165.202.130). What can be done so that R1 will learn about this network?
The correct answer is B. Configure an explicit network command for the 172.16.10.0 subnet on R2. By default, BGP does not accept subnets redistributed from IGP. To advertise and carry subnet routes in BGP, use an explicit network command or the no auto-summary command. If you disable auto-summarization and have not entered a network command, you will not advertise network…

Explanation
By default, BGP does not accept subnets redistributed from IGP. To advertise and carry subnet routes in BGP, use an explicit network command or the no auto-summary command. If you disable auto-summarization and have not entered a network command, you will not advertise network routes for networks with subnet routes unless they contain a summary route.
