1. Configure area 0 on the routers. Ensure that multicast OSPF packets are not allowed between R1, R2, and R3, and R3 is elected designated router.
2. Configure R1 to ignore the MTU parameter when receiving DBD packets on the F0/0 interface.
3. Configure R3 to display routers in the OSPF domain by names rather than by the router IDs. The DNS server IP address is 111.111.123.1.
4. Configure R3 to send a Syslog message when a neighbor goes up or down, and for each state change.
5. The number of self-generated LSAs that the OSPF routing process on R2 can keep in the OSPF link-state database is 1200. If the number reaches the value of 6000, a Syslog message should be generated. Configure R2 to accomplish this.
