Configure the router Ethernet interface:
- router Ethernet interface used for local area network (LAN) directly have received gateway router in the network terminal equipment, each Ethernet interface must have an IP address and a subnet mask to route IP packets,
Configure the Ethernet interface:
Router>
Router> The enable # to enter privileged mode
Router # # config t into global mode
The Router (config) # interface FastEthernet 0/0 # enter interface configuration mode
The Router (config - if) # IP address 192.168.10.11 255.255.255.0 # specified interface IP address and subnet mask
The Router (config - if) # # no shutdown starting f0/0 interface
The Router (config - if) # # exit exit interface configuration mode
The Router (config) # # exit out of the global model
Router # # disable exit privileged mode

Configure the router serial interface
Serial interface used by wan connection for remote sites or ISP router,
Router> The enable
The router # config t
The Router (config) # interface serial 2/0
The Router (config - if) # IP address 192.168.20.100 255.255.255.0
The Router (config - if) 56000 # # clock rate if the connection is the DCE cable, then set the clock frequency; If the connection is DTE cable, skip this step,
The Router (config - if) # no shutdown
The Router (config - if) # description Connects to the main switch in Building A # configuration interface description
Switch interface configuration:
Switch interface is enabled by default,
Switch> The enable
Switch# configure terminal
The Switch (config) # interface FastEthernet 0/1
The Switch (config - if) # description To TAM Switch
The Switch (config - if) # exit
The Switch (config) # hostname Flour_Bluff
Flour_Bluff (config) # exit
Flour_Bluff #
To manage the switch, need to allocate the address, the address of the switch are allocated to the virtual interface called interface virtual local area network (VLAN), in most cases, the interface for VLAN1, this interface is similar to the physical interface of the router, need through the
No shutdown command to start the interfaces,
Flour_Bluff # config t
Flour_Bluff (config) # interface vlan 1
Flour_Bluff (config - if) # IP address 192.168.2.10 255.255.255.0
Flour_Bluff (config - if) # no shutdown
Flour_Bluff (config) # IP default gateway - 192.168.1.1 # switches need a gateway to communicate with outside of the local network equipment
Flour_Bluff (config) # exit
Flour_Bluff #
CodePudding user response:
I've given up using the simulator, the function is too little, cannot be modified OSPF network type, also can't configuration ISIS network,CodePudding user response:
Layer 3 switches on the lack of many services, such as DHCP, have dedicated server, it is not convenient
