The correct answer is D. On each of the IRF virtual switches, enable opaque LSAs and set the OSPF graceful restart mode to IETF mode. See the full explanation below for the reasoning.
Question
Exhibit 1 shows a simplified network topology. All infrastructure devices shown in the exhibit are successfully implementing (OSPF) on the interfaces. The exhibit also shows settings for OSPF areas. Exhibit 2 shows additional settings on IRF. The master within IRF 1 fails. Connectivity is disrupted for about one minute. What can the network administrator do to prevent this issue occurring again?
Options
- ASet up OSPF Bidirectional Forwarding Detection (BFD) on the routed link aggregation groups between the IRF virtual switches
- BEnable extended Link Access Control Detection Data Units (LACPDUs) on IRF 1 and IRF 4
- COn IRF 1, set up Bidirectional Forwarding Detection (BFD) Multi-Access Detection (MAD) with a dedicated link.
- DOn each of the IRF virtual switches, enable opaque LSAs and set the OSPF graceful restart mode to IETF mode.
