Refer to the exhibit. R1 and R2 cannot form an EIGRP adjacency.

Which action establishes the EIGRP adjacency?

  • A Remove the current autonomous system number on one of the routers and change to a different value.
  • B Add the passive-interface command to the R1 configuration so that it matches the R2 configuration.
  • C Remove the passive-interface command from the R2 configuration so that it matches the R1 configuration.
  • D Add the no auto-summary command to the R2 configuration so that it matches the R1 configuration.
Explanation

An EIGRP passive interface does not form neighbor adjacencies because it suppresses EIGRP hello packets and routing updates on that interface. Removing passive-interface FastEthernet0/0 from R2 allows R1 and R2 to exchange EIGRP hellos across their shared subnet and become neighbors.
