Assuming that EIGRP is enabled on both routers and automatic summarization is enabled, what must be configured to ensure that R1 will be able to reach the 2.2.2.0/24 network?

Assuming that EIGRP is enabled on both routers and automatic summarization is enabled, what must be configured to ensure that R1 will be able to reach the 2.2.2.0/24 network?

• Use the command ip address-summary to ensure that R1 recognizes the 2.2.2.0 network.
• Use the command no auto-summary to disable automatic summarization.
• EIGRP does not support VLSM and therefore cannot be used with discontiguous networks.
• EIGRP supports VLSM and will automatically recognize the 2.2.2.0 network.

Explanation: The networks 2.1.1.0/24 and 2.2.2.0/24 are two subnets of the Class A network 2.0.0.0/8. When automatic summarization is enabled, EIGRP will summarize and advertise networks at the major network boundary. In this case, both routers will advertise the network 2.0.0.0/8, which will cause failure of connectivity.
