At a minimum, here is what you need to configure:
- Connect all devices as shown
- Configure all ports with approrpriate addresses and bring them online
- Configure ssh access only with a password of cisco
- Configure a username of cisco and secret of cisco
- Configure an enable secret of cisco
- Ensure that the routers will not mistaken letters for DNS names
- Disable enable timeouts
- Set hosts with IPs so you can use their names instead of IP addresses
- Configure EIGRP and advertise networks based on subnet with no automatic summarization, do not configure Canada nor advertise its networks!
- Exclude the first 10 addresses in all ranges in the private networks for DHCP
- Configure DHCP for all Offices with a /24 subnet based on the network assigned
- Assign default routes to point to the local primary gateway of each site (not the office GWs)
- Ensure all PCs get their DHCP addresses assigned to them and they can ping to their local GW
- Configure the Frame Relay DLCIs as shown and map them as indicated
- The FR-Switch should not have any other configuration as it is acting like a cloud
- Assign static routes to get to Canada based on location (Texas will be a end all be all GW if other primary gateways don't know the correct path
- Configure NAT for Canada to use the internet IP with PAT
- Ensure all devices can ping to the private network in Canada
- Ensure Canada can ping from internal to any CORP based internal IP (i.e. 10.0.3.11, 10.0.0.1)
- Configure EIGRP md5 authentication for all links
- Make sure that any loopback interfaces assigned are being seen as their subnet in the routing tables
- Block all telnet traffic from all locations except Texas
- Block all SSH traffic on private LANs on all sites except Texas
- Verify NAT on the Canada GW
- Enable password encrpytion globally so that any plain text passwords are garbled at minimum security.
