Although summarization is configured for R1 to receive 10.0.0.0/8. more specific routes are received by R1.
How should the 10.0.0.0/8 summary route be received from the neighbor, attached to R1 via Fast Ethernet0/0 interface?

• A.R1 should configure the ip summary-address eigrp <AS number> 10.0.0.0 0.0.0.255 command under the Fast Ethernet 0/0 interface.
• B.The summarization condition is not met Router 10 1 100.10 requires a route for 10 0.0.0/8 that points to null 0
• C.R1 should configure the ip summary-address eigrp <AS number> 10.0.0.0.255.0.0.0 command under the Fast Ethernet 0/0 interface.
• D.The summarization condition is not met. The network 10.1.100.0/24 should be changed to
