Task 1: Apply Basic Router Configurations
Step 1: Configure basic commands.

Using the information in the topology diagram and addressing table, configure the basic device configurations on R1, R2, and R3. Hostnames are configured for you.

Task 2: Configure Dynamic and Default Routing
Step 1. Configure default routing.

R2 needs a default route. Use the exit-interface argument in the default route configuration.

R2(config)#ip route 0.0.0.0 0.0.0.0 s0/1/0

Step 2. Configure dynamic routing.
Configure RIPv2 on R1, R2, and R3 for all available networks. R2 needs to pass its default network configuration to the other routers. Also, be sure to use the passive-interface command on all active interfaces not used for routing.

R1
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#network 10.1.1.0
R1(config-router)#network 192.168.10.0
R1(config-router)#passive-interface f0/1
R1(config-router)#no auto-summary
R1(config-router)#exit
R1(config)#

R2
R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#network 10.1.1.0
R2(config-router)#network 192.168.20.0
R2(config-router)#default-information originate
R2(config-router)#passive-interface s0/1/0
R2(config-router)#passive-interface f0/1
R2(config-router)#no auto-summary
R2(config-router)#exit
R2(config)#

R3
R3(config)#router rip
R3(config-router)#version 2
R3(config-router)#network 10.1.1.0
R3(config-router)#network 192.168.30.0
R3(config-router)#passive-interface f0/1
R3(config-router)#no auto-summary
R3(config-router)#exit
R3(config)#

Task 5: Apply ACL Policies
Step 1. Create and apply security policy number 1.

Implement the following ACL rules using ACL number 101:
Allow hosts on the 192.168.30.0/24 network web access to any destination.
Allow hosts on the 192.168.30.0/24 network ping access to any destination.
Deny any other access originating from the network.

R3
R3(config)#access-list 101 permit tcp 192.168.30.0 0.0.0.255 any eq www
R3(config)#access-list 101 permit icmp 192.168.30.0 0.0.0.255 any
R3(config)#access-list 101 deny ip any any
R3(config)#int fa0/1
R3(config-if)#ip access-group 101 in
R3(config-if)#exit
R3(config)#

Step 2. Create and apply security policy number 2.
Because ISP represents connectivity to the Internet, configure a named ACL called FIREWALL in the following order:
Allow TW-DSL web access to the Intranet server.
Allow TW-Cable web access to the Intranet server.
Allow only inbound ping replies from ISP and any source beyond ISP.
Allow only established TCP sessions from ISP and any source beyond ISP.
Explicitly block all other inbound access from ISP and any source beyond ISP.

R2
R2(config)#ip access-list extended FIREWALL
R2(config-ext-nacl)#permit tcp host 192.168.1.10 host 192.168.20.254 eq www
R2(config-ext-nacl)#permit tcp host 192.168.2.10 host 192.168.20.254 eq www
R2(config-ext-nacl)#permit icmp any any echo-reply
R2(config-ext-nacl)#permit tcp any any established
R2(config-ext-nacl)#deny ip any any
R2(config-ext-nacl)#int s0/1/0
R2(config-if)#ip access-group FIREWALL in
R2(config-if)#exit
R2(config)#
