Configuring Cisco Router as a Dhcp Server

Step 1: Assign ip addresses on both routers as shown in figure. Step 2(A): Define Static route on RA for network 12.0.0.0 RA(config)#ip route 12.0.0.0 255.0.0.0 13.0.0.2 Step 2(B): Define Static route on RB for network 11.0.0.0 RB(config)#ip route 11.0.0.0 255.0.0.0 13.0.0.1 Step 3: Enable DHCP service on RA RA(config)#service dhcp

RA(config)#ip dhcp pool Head-off RA(dhcp-config)#network 11.0.0.0 255.0.0.0 RA(dhcp-config)#default-router 11.0.0.10 Step 4(B): On RA, reserve addresses (11.0.0.1 ~11.0.0.10)by excluding them from the dhcp pool. RA(config)#ip dhcp excluded-address 11.0.0.1 11.0.0.10 Step 5(A): On RA, create & configure dhcp pool Branch-off for branch office hosts. RA(config)#ip dhcp pool Branch-off RA(dhcp-config)#network 12.0.0.0 255.0.0.0 RA(dhcp-config)#default-router 12.0.0.10 Step 5(B): On RA, reserve addresses (12.0.0.1 ~12.0.0.10)by excluding them from the dhcp pool. RA(config)#ip dhcp excluded-address 12.0.0.1 12.0.0.10 Step 6: On head office PC, run the following commands on command prompt C :\> ipconfig /release C :\> ipconfig /renew (Noth that the PC will get an ip address from the Head-off pool) Step 7: On RB, configure helper address on interface Ethernet 0 RB(config)#interface ethernet0 RB(config-if)#ip helper-address 13.0.0.1 Step 8: On Branch office PC, run the following commands on command prompt C :\> ipconfig /release C :\> ipconfig /renew (Noth that the PC will get an ip address from the Branch-off pool) Step 9: On RA, check the DHCP binding by the following command RA#show ip dhcp binding

Configuring OSPF for IPV6

Requirements

PC1 and PC2 running Win2003 Operating System. 2811 and 871 routers with IOS 12.4 (Advance IP Services).

Configuration Step 1: Install & Assign IPv6 addresses and default-gateways on both PCs as per diagram. Step 4: Enable IPv6 routing on 2811 router. 2811(config) # ipv6 unicast-routing Step 5(A): On 2811, enable IPv6 on interface FastEthernet0/1 & assign IPv6 address. 2811(config) #interface FastEthernet0/1 2811(config-if) # ipv6 enable 2811(config-if) # ipv6 address 10::10/64 Step 5(B): On 2811, enable IPv6 on interface FastEthernet0/0 & assign IPv6 address. 2811(config) #interface FastEthernet0/0 2811(config-if) # ipv6 enable 2811(config-if) # ipv6 address 13::1/64 Step 6: Configure OSPF on 2811 router. 2811(config) # ipv6 router ospf 64
