Lab 2-1: Subnet Design

Commands to navigate different modes on a Cisco Switch/Router (enable, config t...) and how you know what mode you are in

• enable - show config
• config t - enter configuration mode
• config-if - enter interface to make changes
• IP routing - enable VLAN routing

Commands to create VLANS on switch

• vlan # (# = vlan number)
• name test (test = the name of the vlan)
• end

Setting access and trunk ports on switch

• switchport mode trunk
• switchport mode trunk vlan #
• end

OR

• switchport mode access
• switchport access vlan #
• end

Configure interfaces in "ranges"

• interface range fastethernet 0/1-4

VLAN IP

• int vlan #
• ip address 0.0.0.0 255.255.255.0

Lab 3-3: DHCP

How to create pools

• In services tab, enable dhcp
• Create the name and then the correct info

Working with serverPool

• Max users should be to the closest possible number for the subnet
• Start DHCP at ~25-50
• Make sure to select the right information

Assigning ip helper addresses

• config t, interface vlan #
• ip helper-address IP_of_the_DHCP_server
• Make sure to do it for each vlan

Any issues you encountered

• Always triple check IPs
• Only address main multilayer switch

Lab 4-1

Console to switch

• Via PuTTY change connection to serial and find the right COM number for the switch
• Change flow control to none

Resetting the Switch

• write erase
• reload
• Say no to setup guide

Lab 4-2: Network in PT

Things to note:

• Create the VLANs' on the distribution area
• Make sure for any on 1 to run no shut
• Remember to set IPs for VLANs

Identify any issues your ran into and how you resolved

• VLAN 1 was shutdown, used no shut
• interface range fastethernet 0/#-#
• switchport mode access vlan # or switchport mode trunk vlan #

LAB 8-1

Enable OSPF

R1(config)# router ospf instance-id

• instance-id can be 1

R1(config-router)# network net-addr wildcard-mask area area-number

• net-addr is the network address of the directly connected network
• wildcard-mask is the wildcard mask of the directly connected network
• area-number can be 0

LAB 9-2

Basic commands

• Define the router instance:

(config)# router bgp AS-number-of-router

• Identify neighboring networks:

(config-router)# neighbor ip-of-peer remote-as AS-number-of-peer

• Advertise Networks within the AS:

(config-router)# network net-addr mask net-mask
