Hold-down timers are used to prevent networks that were previously advertised as down from being placed back into the routing table. When a router receives an update that a network is down, it begins its hold-down timer. This timer tells the router to wait for a specific amount of time before accepting any changes to the status of that network. We have covered a lot of ground so far. Don’t worry about how much is left to learn though. Review the main learning points from switch security, routing concepts, static routing and RIP. overhead in a switched network, whilst enabling switches to exchange and maintain consistent VLAN information. This concept is illustrated in Figure Automatic network summarization is not in effect %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down Sending 5,300-615 dumps, 100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds: CAM table overflow attacks MAC spoofing attacks Router(config-subif)#ip add 10.20.20.254 255.255.255.0 Router(config-subif)#int g0/1 Topology You will actually learn much more about troubleshooting RIP when you get to the configuration labs. Instructions 2.Add a console password to the switch of cisco. Interface must be up/up Encapsulation must match both sides desirable Set trunking mode dynamic negotiation parameter to DESIRABLE Switch(config-if)#switchport mode dynamic desirable all The following are examples of problems and possible solutions: Trunk down? Learn how to configure inter-VLAN routing using router subinterfaces. R1(config)#router rip 2.7.fErr-disable recovery Day 14 – DHCP, DNS and NTP As you can see above, the host IP address is 192.168.1.10 and the next hop in order to reach that host is 10.0.0.1. Subnet mask Domain name server Domain name Router#conf t Switch(config)#int f0/1 Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: dot1q Negotiation of Trunking: On Media Attachment Unit type: 10 Vlan ID: 1 1.Connect a PC or laptop to your switch. In addition, set up a console connection for your configuration. The port to which you connect your PC will be the one you configure security settings on in this lab. I have chosen FastEthernet 0/1 on my switch. R1(config-if)#int f0/0 5.Issue the show vlan brief command to check the interfaces are in VLAN 2. Maximum path: 4 Routing for Networks: Serial0/0 R1(config-if)#ip add 172.16.1.1 255.255.0.0 R1(config-if)#no shut 2.5.a Trunk ports Challenge 2 – Trunking, VLANs and DTP Lab All switches must be configured with the same VTP domain name if they are to exchange VLAN information, as illustrated in the output below: Static secure MAC addresses are statically configured by network administrators and are stored in the MAC address table, as well as in the switch configuration. When static secure MAC addresses are assigned to a secure port, the switch will not forward frames that do not have a source MAC address that matches the configured static secure MAC address or addresses. Switch(config)#int f0/1 3.DHCP Request packet: Once the client workstation receives an offer made by the DHCP server, it will send a broadcast (to let all DHCP servers learn that it has accepted an offer from a server) DHCP Request message to a specific DHCP server, again using UDP source port bootpc 68 and destination port bootps 67. The client might have received offers from multiple DHCP servers, but it only needs a single IP address so it must choose a DHCP server (based on an identifier), and this is usually done on a “first-come, first-served” basis.
