CAM table overflow attacks MAC spoofing attacks 3.1.aPacket handling along the path through a network IA - OSPF inter area, N1 - OSPF NSSA external type 1, Passive interfaces Routing protocol classes Topology Default gateway: 192.168.1.1 (the router interface assigned to the network it serves as a DHCP server) transport input ssh telnet Figure 6.2 below illustrates the valid combinations that will result in the successful establishment of a trunk link between two neighboring switches – one using DTP and the other statically configured as a trunk port: tcp-small-servers Enable small TCP servers (e.g.,350-801 color book, ECHO) telnet-zeroidle Set TCP window 0 when connection is idle timestamps Timestamp debug/log messages Router0#show cdp neighbors detail Device ID: Switch0 Switch(config)#vtp pruning Capability codes: (R) Router, (B) Bridge, (T) Telephone, I suggest that you learn to configure all three types and test them by logging in to the router. You will have different choices depending upon your platform and IOS: By having the lease process in place and correlated to the timers presented above, you can be assured that you will always have an IP address in a timely manner without any downtime associated with this and will automatically have a way to build redundancy into the DHCP process. 2.7.eViolation actions R2(config-if)#int lo0 Interface IP-Address OK? Method Status Protocol 9.Change the MAC address on your PC, or if you can’t do this, plug another device into the switch port. This should make the port shut down due to a breach in the security settings. The screenshot below shows where you would change the MAC address in Packet Tracer. Router(config)#int FastEthernet0/0 If you check the routing table, you will see the administrative distance for RIP and the output we covered earlier: Invalid after 0 seconds, hold down 0, flushed after 0 Outgoing update filter list for all interfaces is not set Incoming update filter list for all interfaces is not set Redistributing: isis 13. The starting and ending points of the vector are not relevant. Instead, the only thing that actually matters is how long the vector is and how far it travels. Banner messages can be: By default, port security is disabled; however, this feature can be enabled using the switchport port-security [mac-address {mac-address} [vlan {vlan-id Let’s implement two different routes into the routing table using each method and see if you can discern the different behavior in the routing table. Packet Forwarding Enabled: yes Day 11 Labs 3.2Interpret the components of routing table You need to enter a wildcard mask if you want your ACL to match a subnet or an entire network. For example, if you wanted to match 172.20.1.0 255.255.224.0, you would enter the following: Command syntax for ACLs In Cisco IOS software, a device is configured with the IP addresses of one or more NTP servers using the ntp server [address] global configuration command. As previously stated, multiple NTP reference addresses can be specified by repeatedly using the same command. In addition, this command can also be used to configure security and other features between the server and the client. The following configuration example illustrates how to configure a device to synchronize its time with an NTP server with the IP address 10.0.0.
