Section 9: Security (7 Points)
You are concerned that you cannot trust some users on VLAN_25. Configure the interfaces for R1 and R5 to authenticate the routing protocol updates through the LAN with the best authentication method.
If you configured this correctly as shown in Example 6-52, you have scored 2 points.
Here we have an OSPF interface authentication configuration. The authentication is starting here intentionally to exercise with something that can break your network. This require-ment could be found also under the specific IGP section but has been left to this stage within the lab.
