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.
