connected to the routers R4 and R5.
The EIGRP routing protocol is configured.
You are required to troubleshoot and resolve the EIGRP issues between the various routers.
Use the appropriate show commands to troubleshoot the issues.

• B.The loopback addresses haven't been advertised, and the network command is missing on R4.
• C.Automatic summarization is enabled, so only the 10.0.0.0 network is displayed.
