so, first of all, I want to thank you guys, sofar for helping me out, after your posts I started to understand it, I'm not 100% with it yet, but I think I'm pretty close to 100% Now I have to learn to calculate the subnet masks.
But with this task, I'm stuck on 85%, I dont understand the meaning of :
The static route on R1-ISP should point to the existing Student LAN subnet via R2-Central's serial interface IP address; the static route on R2-Central should be a default static route which points via R1-ISP's serial interface IP address.
anybody can brake it down for me ? thanks in advance. those are 2 points that are red on the task, in PacketTracer.
and also, the telnet password, I have set it on all devices, but packet tracer does not accept it. it shows as not complete... anybody had same problems ?
this what I did for telnet : line vty 0 4, password cisco, login. and also tryed login first then password. all is accepted but packet tracer says its not configured.
Here is the whole task. :
Task 1: PlanUse the standard Exploration lab topology as you plan your IP addressing scheme:
- Two 1841 routers with WIC-2T interface cards, installed in the right hand slot (one named R1-ISP, which has the serial DCE WAN connection to R2-Central, and the Fa0/0 LAN connection to Eagle_Server) and one named R2-Central (which has the serial DTE WAN connection to R1-ISP and the Fa0/0 LAN connection to S1-Central)
- One 2960TT Switch (S1-Central)
- Two PCs named 1A and 1B
- A server named Eagle_Server.
Note that both the Display names AND host names for all devices must be configured exactly, and, in general, all strings (names, passwords, banners) should be typed exactly as specified in these instructions, in order for Packet Tracer to grade the Activity properly.
You have been given an IP address block of 192.168.3.0 /24. You must provide for existing networks as well as future growth.
Subnet assignments are:
- 1st subnet, existing student LAN, up to 28 hosts (Fa0/0 on R2-Central, connected to Fa0/24 on S1-Central)
- 2nd subnet, future student LAN, up to 28 hosts (not yet implemented)
- 3rd subnet, existing ISP LAN, up to 14 hosts (Fa0/0 on R1-ISP)
- 4th subnet, future ISP LAN, up to 7 hosts (not yet implemented)
- 5th subnet, existing WAN, point-to-point link (S0/0/0 on R1-ISP and S0/0/0 on R2-Central)
IP address assignments are:
Task 2: Build and configure the network
- For the server, configure the second highest usable IP address on the ISP LAN subnet.
- For R1-ISP's Fa0/0 interface, configure the highest usable IP address on the ISP LAN subnet.
- For R1-ISP's S0/0/0 interface, configure the highest usable address on the existing WAN subnet.
- For R2-Central's S0/0/0 interface, use the lowest usable address on the existing WAN subnet.
- For R2-Central's Fa0/0 interface, use the highest usable address on the existing student LAN subnet and connect it to the Fa0/24 interface on S1-Central.
- For hosts 1A and 1B, use the first 2 IP addresses (two lowest usable addresses) on the existing student LAN subnet and connect them to the Fa0/1 and Fa0/2 interfaces on S1-Central.
- For the switch management interface, use the second highest usable address on the student subnet.
Build the network, taking care to make connections as specified. Configure both routers, the switch, the server, and the two PCs.
Configure the routers using the CLI. The router configuration must include "housekeeping" (hostname, passwords, banner), interfaces (Fast Ethernet and Serial), and routing (static route on R1-ISP, default route on R2-Central). The following login passwords should all be set to "cisco" (no quotes): enable secret, console, and Telnet. The banners should say **This is lab router R1-ISP. Authorized access only.** and **This is lab router R2-Central. Authorized access only.**
The interfaces should be configured as specified in the IP addressing section above; use a clock rate of 64000 on the R1-ISP S0/0/0 interface. The static route on R1-ISP should point to the existing Student LAN subnet via R2-Central's serial interface IP address; the static route on R2-Central should be a default static route which points via R1-ISP's serial interface IP address. Whenever you configure a Cisco IOS device, be sure to save your configuration.
On the switch, configure the hostname, banner (**This is lab switch S1-Central. Authorized access only.**), login passwords for access (enable secret password, console, and Telnet passwords all set to "cisco"), and management interface (interface vlan1). Whenever you configure a Cisco IOS device, be sure to save your configuration.
For Hosts 1A and 1B, in addition to IP configuration, configure them to use DNS services. For the server, enable DNS services, use the domain name eagle-server.example.com, and enable HTTP services.
I have the next config :
R1 : Serial : 192.168.3.98
R1 : FA : 192.168.3.78
R2 : Serial : 192.168.3.97
R2 : FA : 192.168.3.30
Eagle Server : 192.168.3.77
switch : 192.168.3.29 (vlan 1) management
PCa : 192.168.3.1
PCb : 192.168.3.2
I have tested the connection from pc's to eagle server, and I can reach the www. So sofar all is alright.
Because I didnot learn how to calculate subnet masks, I temporarly used a subnet calculator for that, but all other stuff is thanks to your help guys. much much much thanks for that.
basicly in 10 years working as IT guy, I never learned calculating subnets, cause I never needed it. But you guys helped me out, I'm just sitting here and writing on a block of paper and calculating it thanks allot.
