ROUTER 2921 Configuration

IPV4 and Connectivity -

Configure Device basic Settings

• Booting up the Cisco router for the first time, one notices some basic configuration has already been performed. Use the show running-config command to view the initial configuration, as shown in the following example.

Router# show running-configBuilding configuration...Current configuration : 723 bytes!version 12.4no service padservice timestamps debug datetime msecservice timestamps log datetime msecno service password-encryption!hostname Router!boot-start-markerboot-end-marker!logging message-counter syslog!no aaa new-model!no ipv6 cefip source-routeip cef!!!!multilink bundle-name authenticated!!archivelog confighidekeys!!!!!interface GigabitEthernet0/0no ip addressshutdownduplex autospeed auto!interface GigabitEthernet0/1no ip addressshutdownduplex autospeed auto!interface GigabitEthernet0/2no ip addressshutdownduplex autospeed auto!ip forward-protocol nd!no ip http server!!!!!control-plane!!line con 0line aux 0line vty 0 3login!exception data-corruption buffer truncatescheduler allocate 20000 1000end

• Configuring Global Parameters. To configure the global parameters for the router, follow these steps.

SUMMARY STEPS

1.configure terminal

2.hostname name

3.enable secret password

4.no ip domain-lookup

Static / Default Routes

Static routes provide fixed routing paths through the network. They are manually configured on the router. If the network topology changes, the static route must be updated with a new route. Static routes are private routes unless they are redistributed by a routing protocol.

To configure static routes, follow these steps, beginning in global configuration mode.

SUMMARY STEPS

1.ip route prefix mask { ip-address | interface-type interface-number [ ip-address ]}

2.end

Dynamic Routes

In dynamic routing, the network protocol adjusts the path automatically, based on network traffic or topology. Changes in dynamic routes are shared with other routers in the network.

The Cisco routers can use IP routing protocols, such as Routing Information Protocol (RIP) or Enhanced Interior Gateway Routing Protocol (EIGRP), to learn routes dynamically. You can configure either of these routing protocols on your router.

• “Configuring Routing Information Protocol” section

• “Configuring Enhanced Interior Gateway Routing Protocol” section

Configuring Routing Information Protocol

To configure the RIP routing protocol on the router, follow these steps, beginning in global configuration mode.

SUMMARY STEPS

1.router rip

2.version { 1 | 2 }

3.network ip-address

4.no auto-summary

5. end

RIPv2 -

Configuring RIP routing protocol consists of three basic steps:

• Enabling RIP routing protocol on the router

• Specifying the RIP version to run

• Configuring the network addresses to be included in routing updates or specifying the interfaces to participate in routing updates

Vlan and Inter Vlan routing

Access Control Lists (ACLS)

Small service: DHCP and NAT - Configuring Static Routes

Static routes provide fixed routing paths through the network. They are manually configured on the router. If the network topology changes, the static route must be updated with a new route. Static routes are private routes unless they are redistributed by a routing protocol.

To configure static routes, follow these steps, beginning in global configuration mode.

SUMMARY STEPS

1.ip route prefix mask { ip-address | interface-type interface-number [ ip-address ]}

SWITCH 2960 Configuration

• Assign a name to the switch.

  • Here's a review of the commands used. S1#configure terminal S1(config)#hostname S1 S1(config)#exit

• Set the access passwords. Enter config-line mode for the console. Set the login password to cisco. Also configure the vty lines 0 to 15 with the password cisco. S1#configure terminal Enter the configuration commands, one for each line. When you are finished, return to global configuration mode by entering the exit command or pressing Ctrl-Z. S1(config)#line console 0 S1(config-line)#password cisco S1(config-line)#login S1(config-line)#line vty 0 15 S1(config-line)#password cisco S1(config-line)#login S1(config-line)#exit Why is the login command required? _____________________________________________________

• Set the command mode passwords. Set the enable secret password to class. This password protects access to privileged EXEC mode. S1(config)#enable secret class

• Configure the Layer 3 address of the switch. Before you can manage S1 remotely from PC1, you need to assign the switch an IP address. The default configuration on the switch is to have the management of the switch controlled through VLAN 1. However, a best practice for basic switch configuration is to change the management VLAN to a VLAN .other than VLAN 1. The implications and reasoning behind this action are explained in the next chapter. For management purposes, we will use VLAN 99. The selection of VLAN 99 is arbitrary and in no way implies you should always use VLAN 99. First, you will create the new VLAN 99 on the switch. Then you will set the IP address of the switch to 172.17.99.11 with a subnet mask of 255.255.255.0 on the internal virtual interface VLAN 99. S1(config)#vlan 99 S1(config-vlan)#exit S1(config)#interface vlan99 %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan99, changed state to down S1(config-if)#ip address 172.17.99.11 255.255.255.0 S1(config-if)#no shutdown

S1(config-if)#exit S1(config)# Notice that the VLAN 99 interface is in the down state even though you entered the command no shutdown. The interface is currently down because no switchports are assigned to VLAN 99. Assign all user ports to VLAN 99. S1#configure terminal S1(config)#interface range fa0/1 - 24 S1(config-if- range)#switchport access vlan 99 S1(config-if-range)#exit S1(config-if-range)# %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed state to down %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan99, changed state to up .

• Set the switch default gateway. S1 is a layer 2 switch, so it makes forwarding decisions based on the Layer 2 header. If multiple networks are connected to a switch, you need to specify how the switch forwards the internetwork frames, because the path must be determined at Layer three. This is done by specifying a default gateway address that points to a router or Layer 3 switch. Although this activity does not include an external IP gateway, assume that you will eventually connect the LAN to a router for external access. Assuming that the LAN interface on the router is 172.17.99.1, set the default gateway for the switch. S1(config)#ip default-gateway 172.17.99.1 S1(config)#exit

• Verify the management LANs settings. Verify the interface settings on VLAN 99. S1#show interface vlan 99 What is the bandwidth on this interface? ______________________________ What are the VLAN states? VLAN1 is ______________ Line protocol is ______________ What is the queuing strategy? ____________________

• Configure the IP address and default gateway for PC1. Set the IP address of PC1 to 172.17.99.21, with a subnet mask of 255.255.255.0. Configure a default gateway of 172.17.99.11. (If needed, refer to Lab 1.3.1 to configure the PC NIC.)

• Verify connectivity. To verify the host and switch are correctly configured, ping the IP address of the switch (172.17.99.11) from PC1. Was the ping successful? ________________________ If not, troubleshoot the switch and host configuration. Note that this may take a couple of tries for the pings to succeed.

• Configure the port speed and duplex settings for a Fast Ethernet interface. Configure the duplex and speed settings on Fast Ethernet 0/18. Use the end command to return to privileged EXEC mode when finished. S1#configure terminal S1(config)#interface fastethernet 0/18 S1(config-if)#speed 100 S1(config-if)#duplex full S1(config-if)#end %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/18, changed state to down %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan99, changed state to down %LINK-3-UPDOWN: Interface FastEthernet0/18, changed state to down %LINK-3-UPDOWN: Interface FastEthernet0/18, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/18, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan99, changed state to up The line protocol for both interface FastEthernet 0/18 and interface VLAN 99 will temporarily go down. The default on the Ethernet interface of the switch is auto-sensing, so it automatically negotiates optimal settings. You should set duplex and speed manually only if a port must operate at a certain speed and duplex mode. Manually configuring ports can lead to duplex mismatches, which can significantly degrade performance. Verify the new duplex and speed settings on the Fast Ethernet interface. S1#show interface fastethernet 0/18

• Save the configuration. You have completed the basic configuration of the switch. Now back up the running configuration file to NVRAM to ensure that the changes made will not be lost if the system is rebooted or loses power. S1#copy running-config startup-config Destination filename [startup-config]?[Enter] Building configuration... [OK] S1#

• Examine the startup configuration file. To see the configuration that is stored in NVRAM, issue the show startup-config command from privileged EXEC mode. S1#show startup-config Are all the changes that were entered recorded in the file? ______________
