Scenario
In this comprehensive CCNA skills activity, the XYZ Corporation uses a combination of eBGP and PPP for WAN connections. Other technologies include NAT, DHCP, static and default routing, EIGRP for IPv4, inter-VLAN routing, and VLAN configurations. Security configurations include SSH, port security, switch security, and ACLs.
Note: Only HQ, B1, B1-S2, and the PCs are accessible. The user EXEC password is cisco and the privileged EXEC password is class.
Requirements
PPP
- Configure the WAN link from HQ to the Internet using PPP encapsulation and CHAP authentication.
- Create a user ISP with the password of cisco.
- Configure the WAN link from HQ to NewB using PPP encapsulation and PAP authentication.
- Create a user NewB with the password of cisco.
Note: The ppp pap sent-username is not graded by Packet Tracer. However, it must be configured before the link will come up between HQ and NewB.
HQ(config)# interface s0/1/0 HQ(config-if)# encapsulation ppp HQ(config-if)# ppp authentication chap HQ(config-if)# exit HQ(config)# username ISP password cisco HQ(config)# interface s0/0/1 HQ(config-if)# encapsulation ppp HQ(config-if)# ppp authentication pap HQ(config-if)# ppp pap sent-username HQ password cisco HQ(config-if)# exit HQ(config)# username NewB password cisco
eBGP
- Configure eBGP between HQ and the Internet.
- HQ belongs to AS 65000.
- The IP address for the BGP router in the Internet cloud is 209.165.201.2.
- Advertise the 192.0.2.0/24 network to the Internet.
HQ(config)# router bgp 65000 HQ(config-router)# neighbor 209.165.201.2 remote-as 65001 HQ(config-router)# network 192.0.2.0 mask 255.255.255.0
NAT
- Configure dynamic NAT on HQ
- Allow all addresses for the 10.0.0.0/8 address space to be translated using a standard access list named NAT.
- XYZ Corporation owns the 209.165.200.240/29 address space. The pool, HQ, uses addresses .241 to .245 with a /29 mask. Bind the NAT ACL to the pool HQ. Configure PAT.
- The connections to the Internet and HQ-DataCenter are outside XYZ Corporation.
HQ(config)# ip access-list standard NAT HQ(config-std-nacl)# permit 10.0.0.0 0.255.255.255 HQ(config-std-nacl)# exit HQ(config)# ip nat pool HQ 209.165.200.241 209.165.200.245 netmask 255.255.255.248 HQ(config)# ip nat inside source list NAT pool HQ overload HQ(config)# interface s0/1/0 HQ(config-if)# ip nat outside HQ(config-if)# interface g0/1 HQ(config-if)# ip nat outside HQ(config-if)# interface s0/0/0 HQ(config-if)# ip nat inside HQ(config-if)# interface s0/0/1 HQ(config-if)# ip nat inside HQ(config-if)# interface g0/0 HQ(config-if)# ip nat inside
Inter-VLAN Routing
- Configure B1 for inter-VLAN routing.
- Using the addressing table for branch routers, configure and activate the LAN interface for inter-VLAN routing. VLAN 99 is the native VLAN.
B1(config)# interface g0/0 B1(config-if)# no shutdown B1(config-if)# interface g0/0.10 B1(config-subif)# encapsulation dot1q 10 B1(config-subif)# ip address 10.1.10.1 255.255.255.0 B1(config-subif)# interface g0/0.20 B1(config-subif)# encapsulation dot1q 20 B1(config-subif)# ip address 10.1.20.1 255.255.255.0 B1(config-subif)# interface g0/0.30 B1(config-subif)# encapsulation dot1q 30 B1(config-subif)# ip address 10.1.30.1 255.255.255.0 B1(config-subif)# interface g0/0.99 B1(config-subif)# encapsulation dot1q 99 native B1(config-subif)# ip address 10.1.99.1 255.255.255.0
Static and Default Routing
- Configure HQ with a static route to the NewB LAN. Use the exit interface as an argument.
- Configure B1 with a default route to HQ. Use the next-hop IP address as an argument.
HQ(config)# ip route 10.4.5.0 255.255.255.0 serial 0/0/1 B1(config)# ip route 0.0.0.0 0.0.0.0 10.255.255.1
EIGRP Routing
- Configure and optimize HQ and B1 with EIGRP routing.
- Use autonomous system 100.
- Disable EIGRP updates on appropriate interfaces.
HQ(config)# router eigrp 100 HQ(config-router)# network 10.0.0.0 HQ(config-router)# passive-interface g0/0 HQ(config-router)# passive-interface s0/0/1
B1(config)# router eigrp 100 B1(config-router)# network 10.0.0.0 B1(config-router)# passive-interface g0/0.10 B1(config-router)# passive-interface g0/0.20 B1(config-router)# passive-interface g0/0.30 B1(config-router)# passive-interface g0/0.99
VLANs and Trunking Configurations
Note: Logging to the console is turned off on B1-S2 so that the Native VLAN mismatch messages will not interrupt your configurations. If you would prefer to view console messages, enter the global configuration command logging console.
- Configure trunking and VLANs on B1-S2.
- Create and name the VLANs listed in the VLAN Configuration and Port Mappings table on B1-S2 only.
- Configure the VLAN 99 interface and default gateway.
- Set trunking mode to on for F0/1 – F0/4.
- Assign VLANs to the appropriate access ports.
- Disable all unused ports and assign the BlackHole VLAN.
B1-S2(config)# vlan 10 B1-S2(config-vlan)# name Admin B1-S2(config-vlan)# vlan 20 B1-S2(config-vlan)# name Sales B1-S2(config-vlan)# vlan 30 B1-S2(config-vlan)# name Production B1-S2(config-vlan)# vlan 99 B1-S2(config-vlan)# name Mgmt&Native B1-S2(config-vlan)# vlan 999 B1-S2(config-vlan)# name BlackHole B1-S2(config)# interface vlan 99 B1-S2(config-if)# ip address 10.1.99.22 255.255.255.0 B1-S2(config-if)# exit B1-S2(config)# ip default-gateway 10.1.99.1 B1-S2(config)# interface range f0/1 - 4 B1-S2(config-if-range)# switchport mode trunk B1-S2(config-if-range)# switchport trunk native vlan 99 B1-S2(config-if-range)# exit B1-S2(config)# interface f0/6 B1-S2(config-if)# switchport mode access B1-S2(config-if)# switchport access vlan 10 B1-S2(config-if)# interface f0/11 B1-S2(config-if)# switchport mode access B1-S2(config-if)# switchport access vlan 20 B1-S2(config-if)# interface f0/16 B1-S2(config-if)# switchport mode access B1-S2(config-if)# switchport access vlan 30 B1-S2(config-if)# exit B1-S2(config)# interface range f0/5, f0/7-10, f0/12-15, f0/17-24, g0/1-2 B1-S2(config-if-range)# switchport access vlan 999 B1-S2(config-if-range)# shutdown
Port Security
- Use the following policy to establish port security on the B1-S2 access ports:
- Allow two MAC addresses to be learned on the port.
- Configure the learned MAC addresses to be added to the configuration.
- Set the port to send a message if there is a security violation. Traffic is still allowed from the first two MAC addresses learned.
B1-S2(config)# interface range f0/6, f0/11, f0/16 B1-S2(config-if-range)# switchport port-security B1-S2(config-if-range)# switchport port-security maximum 2 B1-S2(config-if-range)# switchport port-security mac-address sticky B1-S2(config-if-range)# switchport port-security violation restrict
SSH
- Configure HQ to use SSH for remote access.
- Set the modulus to 2048. The domain name is CCNASkills.com.
- The username is admin and the password is adminonly.
- Only SSH should be allowed on VTY lines.
- Modify the SSH defaults: version 2; 60-second timeout; two retries.
HQ(config)# ip domain-name CCNASkills.com HQ(config)# crypto key generate rsa HQ(config)# username admin password adminonly HQ(config)# line vty 0 4 HQ(config-line)# transport input ssh HQ(config-line)# login local HQ(config-line)# exit HQ(config)# ip ssh version 2 HQ(config)# ip ssh time-out 60 HQ(config)# ip ssh authentication-retries 2
DHCP
- On B1, configure a DHCP pool for the Sales VLAN 20 using the following requirements:
- Exclude the first 10 IP addresses in the range.
- The case-sensitive pool name is VLAN20.
- Include the DNS server attached to the HQ LAN as part of the DHCP configuration.
- Configure the Sales PC to use DHCP.
B1(config)# ip dhcp excluded-address 10.1.20.1 10.1.20.10 B1(config)# ip dhcp pool VLAN20 B1(dhcp-config)# network 10.1.20.0 255.255.255.0 B1(dhcp-config)# default-router 10.1.20.1 B1(dhcp-config)# dns-server 10.0.1.4
Click Sales PC > Desktop > IP Configuration
Change to DHCP and verify PC gets addressing information
Access List Policy
- Because HQ is connected to the Internet, configure and apply a named ACL called HQINBOUND in the following order:
- Allow inbound BGP updates (TCP port 179) for any source to any destination.
- Allow inbound HTTP requests from any source to the HQ-DataCenter network.
- Allow only established TCP sessions from the Internet.
- Allow only inbound ping replies from the Internet.
- Explicitly block all other inbound access from the Internet.
HQ(config)# ip access-list extended HQINBOUND HQ(config-ext-nacl)# permit tcp any any eq 179 HQ(config-ext-nacl)# permit tcp any 192.0.2.0 0.0.0.255 eq www HQ(config-ext-nacl)# permit tcp any any established HQ(config-ext-nacl)# permit icmp any any echo-reply HQ(config-ext-nacl)# deny ip any any HQ(config-ext-nacl)# exit HQ(config)# interface s0/1/0 HQ(config-if)# ip access-group HQINBOUND in
Connectivity
- Verify full connectivity from each PC to WWW.pka and www.cisco.pka.
- The Outside Host should be able to access the webpage at WWW.pka.
- All the test in Scenario 0 should be successful.
