Hi, I'm a student and I am trying to setup a Cisco 3 layer modeled Campus network. I'm so far done setting up the Cores, Distribs and Access' but I am stuck setting up the border. Can, please, anyone help me on this, by giving hints or atleast post a link of an article regarding my problem. Thank you.
configure interface fa 0/0 as follows: ip address 192.168.*.* 255.255.255.0
(use the next available ip in 192.168.10 network) (DONE)
configure interface fa0/1 as follows:
ip address 155.13*.***.245 255.255.255.0 (DONE)
Configure OSPF routing protocol
configure static route to send all trafic through 155.135.55.245
Configure NAT (network address translation) with the following info
nat pool ip 155.13*.***.219
use the interface fa0/1 as the outbound NAT address (PAT)
fa 0/0 will be uses as nat inside and fa0/1 as nat outside
use various show command to see the status of NAT

Hi,
1. Check this link for NAT configuration & Show coomands/ Troubleshooting for NAT:
http://www.cisco.com/en/US/partner/tech/tk648/tk361/technologies_tech_note09186a0080094e77.shtml
2.Static route: basic default route : ip route 0.0.0.0 0.0.0.0
3. OSPF:
This is based on your network requirement (subnets, area etc..).,.but basic configuration..

Thank you mvsheik123, but it seems that the first link is for special members only.
Attached is a screenshot of what I get when I type "router ospf 1"
am I missing anything?

Hi,
The OSPF process can't start if there is no RID( router-id), and that's what the message is saying.
How is router-id derived:
-highest up/up loopback ip address
or
-highest up/up ip address of physical interface
or
- router-id command under router ospf process
Regards.

You need at least one interface to be up/up in the "sh ip int brief" command for OSPF to start. Alternatively you can configure a loopback address on the border router and then OSPF would use this as it's router-id. Or you can specify a router-id specifically under the OSPF configuration.
It looks like none of your interfaces on the border router are up. Have you done eg.
int fa0/0
no shut
Edit - as for the URL link MS provided that you can't access, just remove the /partner/ bit from the URL and you will be able to get to the page.

It worked.. and thank you!
now I have to do this
Configure OSPF routing protocol (DONE, I guess)
will this do the trick?
route if_name dest_ip mask gateway_ip [distance]
Example:
hostname(config)# route outside 10.10.10.0 255.255.255.0 192.168.1.1 [1]
04-30-2011 07:35 AM
route if_name dest_ip mask gateway_ip
This is the command for a PIX/ASA not a router, for a router the command is:
ip route dest_ip mask [gateway_ip or interface]
Configure OSPF routing protocol (DONE, I guess)
Configuring the OSPF process only without telling which route to advertise and on which interface to do neighbourship is useless so you'll have to:
-use the network ip_add inv_mask area area_id command
- or if you've got the IOS supporting it, in interface config use ip ospf pid area area_id
Regards.

cadet alain, so far here is what I did. tnx!

I think my given task is done. I noticed that the configuration can be done for 2-3 minutes and I did it for over a week.. lol
configure interface fa 0/0 as follows: ip address 192.168.*.* 255.255.255.0
(use the next available ip in 192.168.10 network) (DONE)
configure interface fa0/1 as follows:
ip address 155.13*.***.245 255.255.255.0 (DONE)
Configure OSPF routing protocol
configure static route to send all trafic through 155.135.55.245 (DONE)
router ospf 1
network 192.168.0.0 0.0.255.255 area 0
Configure NAT (network address translation) with the following info (DONE)
nat pool ip 155.13*.***.219
ip nat pool name 155.13*.***.219 155.13*.***.219 netmask 255.255.255.0
use the interface fa0/1 as the outbound NAT address (PAT)(DONE)
fa 0/0 will be uses as nat inside and fa0/1 as nat outside
int fa0/0
ip nat inside
exit
int fa0/1
ip nat outside
exit
use various show command to see the status of NAT (DONE)
show ip nat statistics
show ip nat translation
tnx for the help!!
