Layer 3 Technologies

Users report reachability problems between areas immediately after an engineer configures summary routes between areas in a multiple-area OSPF autonomous system.

Which action resolves the issue?

  • A Configure the area range command on the ASBR.
  • B Configure the summary-address command on the ASBR.
  • C Configure the summary-address command on the ABR.
  • D Configure the area range command on the ABR.
Explanation

Interarea OSPF route summarization must be configured on the ABR with the area range command. An ABR advertises the resulting summary between areas; summary-address is used by an ASBR for external-route summarization.
