Kategori : 10 Minute Lab OSPF

Try to solve the lab problem in 10 minutes or less.

Change OSPF configuration of R1's, R2's Ser0/0 interfaces, and R3's Ser0/0.123 sub-interface you have done in the previous lab such that the Frame-Relay network does not need DR/BDR election.
R1 should see IP address of 172.16.123.2 as the next-hop address for subnets advertised by R3 when using S0/0 interface.
R3 should see IP address of 172.16.123.2 as the next-hop address for subnets advertised by R1.
On R3 do NOT use �ip ospf network� command to accomplish full adjacency with R2.
Remove all redundant OSPF/Frame-Relay commands configured in the previous lab (problem 5).
