• Change the router-id of router R2 to 2.2.2.2.
• Implement the command network 192.168.3.1 0.0.0.0 area 0 on router R2.

• Make sure that the router priority is unique on each router.
• Make sure that the DR/BDR election is complete.
• Make sure that the router ID is included in the hello packet.
• Make sure that the hello and dead interval timers are the same on all routers.

160. Refer to the exhibit. The company has decided that no traffic initiating from any other existing or future network can be transmitted to the Research and Development network. Furthermore, no traffic that originates from the Research and Development network can be transmitted to any other existing or future networks in the company. The network administrator has decided that extended ACLs are better suited for these requirements. Based on the information given, what will the network administrator do?

• One ACL will be placed on the R1 Gi0/0 interface and one ACL will be placed on the R2 Gi0/0 interface.
• Only a numbered ACL will work for this situation.
• One ACL will be placed on the R2 Gi0/0 interface and one ACL will be placed on the R2 S0/0/0 interface.(Not sure)
• Two ACLs (one in each direction) will be placed on the R2 Gi0/0 interface.
