Refer to the exhibit. Router R3 is receiving multiple routes through the EIGRP routing protocol. Which statement is true about the implementation of summarization in this network?CCNA3_Ch8_02

  • Automatic summarization has been enabled only for the 172.21.100.0/24 network.
  • Automatic summarization is disabled on R3.
  • Automatic summarization is enabled on neighboring routers.
  • Automatic summarization is disabled on a per-interface basis.

Explanation: Automatic summarization is disabled on R3, so no routes to the null0 interface have been created for networks 172.21.0.0/16 and 192168.254.0/24. If automatic summarization had been enabled on R3 neighbors, the networks that were received by R3 would have been summarized classful statements.
