Multiple Choice

Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)

• A) a new OSPF area for R1 and R2 connections, with R1 and R2 as ABRs
• B) a new OSPF area for R3 and R4 connections, with R5 and R6 as ABRs
• C) a new OSPF area for R3 and R4 connections, with R3 and R4 as ABRs
• D) a new OSPF area for R1, R2, R3, and R4 connections, with R1, R2, R3, and R4 as ABRs
• E) a new OSPF area for R1 and R2 connections, with R5 and R6 as ABRs
