How can I configure a router as a DHCP server and ensure the routing function ?, Vrodhcp configuration dhcp
Dynamic Host Configuration Protocol (DHCP)
Lab Name:Configure the router as a DHCP server and ensure the routing function.
Lab requirements:
1. automatically assign IP addresses to terminal Devices
2. Have the routing function
Lab notes:This experiment requires two PCs and two 2811 vrouters.
Illustration
Experiment Configuration:
(1) configure an IP address for vrorourouter1
① Command implementation:
Router>
Enable
Router #
Config terminal
Router (config )#
Hostname R1
R1 (config )#
Interface fas 0/1
R1 (config-if )#
No shutdown
R1 (config-if )#
Ip address 192.168.1.100 255.255.255.0
R1 (config-if )#
Exit
② Enable the DHCP service:
R1 (config )#
Service dhcp
③ Configure the DHCP address pool
R1 (config )#
Ip dhcp pool dizhichi1
R1 (dhcp-config )#
Network 192.168.1.0 255.255.255.0
R1 (dhcp-config )#
Default-router 192.168.1.100
R1 (dhcp-config )#
End
④ Connect fas0/1 of the router with a crossover line and fas0/0 of the Computer pc0
⑤ Click dhcp on the computer IP address to automatically obtain the IP address. The default IP address is 192.168.1.1 255.255.0.
⑥ Verify and test show ip dhcp binding <view assigned ip addresses>
(2) Configure IP addresses for vrorourouter2
① Command implementation:
Router>
Enable
Router #
Config terminal
Router (config )#
Hostname R2
R2 (config )#
Interface fas 0/1
R2 (config-if )#
No shutdown
R2 (config-if )#
Ip address 192.168.2.100 255.255.255.0
R2 (config-if )#
Exit
② Enable the DHCP service:
R2 (config )#
Service dhcp
③ Configure the DHCP address pool
R2 (config )#
Ip dhcp pool dizhichi2
R1 (dhcp-config )#
Network 192.168.2.0 255.255.255.0
R1 (dhcp-config )#
Default-router 192.168.2.100
R1 (dhcp-config )#
End
④ Connect fas0/1 of vror2 R2 and fas0/0 of pc2.
⑤ Click dhcp in PC2 to automatically obtain the IP address. The default IP address is 192.168.2.1 255.255.255.0.
⑥ Verify and test show ip dhcp binding <view assigned ip addresses>
(3) connect the fas0/0 ports of the two routers respectively with a crossover line.
(4) configure the IP address of fas0/0 in Router R1
R1 (config )#
Inter fas0/0
R1 (config-if )#
No shutdown
R1 (config-if )#
Ip address 10.10.12.1 255.255.255.0
Configure the IP address of fas0/0 in Router R1
R1 (config )#
Inter fas0/0
R1 (config-if )#
No shutdown
R1 (config-if )#
Ip address 10.10.12.1 255.255.255.0
⑹ Configure static route entries for router R1
R1 (config )#
Ip route 192.168.2.0 255.255.255.0 10.10.12.2
Configure a static route entry for router R2.
R2 (config )#
Ip route 192.168.1.0 255.255.255.0 10.10.12.1
Verification and Testing
Show ip route <view route table>
Pc0> ping 192.168.2.1 <pc0 sends a request to pc2>
Experiment summary:The vrodhcp can be configured as a dhcp server to implement the routing function.
