Hi Experts,
I am in process of configuring ospf between dubai router and oman router.The problem
is the both routers have default to route to internet 0.0.0.0 0.0.0.0 214.42.x.x
Can i configure ospf on both routers if yes then how can i configure
any kind of information is appreciated.

Hello,
It seems, that the serial interfaces are directly connected to the internet and the Dubai router can reach the Oman router and the other way aroud? If yes, see below
1. You have to create a tunnel interface on router dubei
interface Tunnel 10 description DUBAI_OMAN ip address 10.0.0.1 255.255.255.252 cdp enable tunnel sourcetunnel source Serial 0/0/0
tunnel destination 212.72.8.x
exit
2. You have to create a tunnel interface on router dubei
interface Tunnel 10 description DUBAI_OMAN ip address 10.0.0.2 255.255.255.252 cdp enable tunnel sourcetunnel source Serial 0/0/0
tunnel destination 213.32.x.x
exit
3. You have to change the router ospf 10 at the Dubai router and include the tunnel network istead of the serial network
router ospf 10 router-id 10.254.0.1 network 10.254.0.1 0.0.0.0 area 0

exit
4. You have to change the router ospf 10 at the Oman router and include the tunnel network istead of the serial network
router ospf 10 router-id 10.254.0.2 network 10.254.0.2 0.0.0.0 area 0

default-information originate always
exit
5. You should now have an unencrypted connection between both routers.

Hello,
no cdp isn't mandatory. It's sometimes only a nice feature to see the neigbours of your device, like "show cdp neighbours" .

Hello,
I have two question:
See attached file INTERNET.TXT
See attached file DARKFIBER.TXT
I think those samples should help, if I got your question right.
In this sample is no focus set to scalability, like subinterfaces, VLAN, VRF, etc.
In both samples the LAN client will have Interet access, if this should not happen, than remove the lines "redistribute static subnets route-map INTERNET-DUBAI" and "redistribute static subnets route-map INTERNET-OMAN"

Hi Kai Onken,
Thanks for your reply.Let me explain you my network setup
R1 is in Oman
ROUTER(R1) :SERIAL1(214.42.X.X/28)
ETHERNET(192.168.14.1/24)
defualt route via serial1 connected to lease line.
R2 is in Dubai ROUTER(R2) :SERIAL1(213.44.X.X/28)
ETHERNET(192.168.10.1/24)
default route via serial1 connect to lease line.
Now i want to configure ospf point to point connectivity between Oman and Dubai
so please assist me if it is possible to configure ospf between R! and R2?

OSPF is an Interior Gateway Protocol (IGP) and it will not pass through a public network.
You need to use some sort of tunneling mechanism (like a VPN or GRE tunnel).
04-21-2013 08:56 PM
Hello Munnawer,
Marvin is right. In this case, you've to use the INTERNET configuration and change the GigabitEthernet 0/1 to your serial connection. Than should your setup work. The point to point connection will be the Tunnel Interface. But notice that the two routers habe to "see" each other throught the internet to create a tunnel.
If you want to do a VPN Tunnel you neet the hole INTERNET configuration. This connection will be encrypted
If you only want a Tunnel, you could remove section starting with CRYPTO. This will be an unencrypted connection.
You've to know, if you encrypt the connection, the bandwith could decrease, based on the routers you will use.
Kind regards

Hi,
I am Getting error while enabling cdp on tunnel interface
DUBAIHOST(config-if)#cdp enable
% CDP is not supported on this interface, or for this encapsulation.
So is it mandatory to enable cdp.?

no cdp isn't mandatory. It's sometimes only a nice feature to see the neigbours of your device, like "show cdp neighbours" .

Hi Kai Onken,
I Thank you very much for all the assistance now every thing is working fine.
i can see the ospf routes in Routing table along with default route.this time i wll choose your answer
is perfect correct.
Dear Kai Onken i need one more favour from your side
do you any good network monitoring commands in cisco or any software to monitor all things like
router bandwidth how much used, free and which application uses how much bandwidth
router,firewall,switches cpu load,each user how much bandwidth utilizing and what kind of services
users are using i mean all things I want to monitor.
Thanks agian for your support .

Munnawer Khan.

Hello,
We're using Nagios at our office. If you don't need any kind of support, you could choose the opensource version
http://www.nagios.org/ additional you can check http://exchange.nagios.org/ for plugins. This should help you.
At the configuration advise you to use the encryption on the Internet connection form the sample at the top.
Kind regards
Kai
04-23-2013 08:35 AM
Hi,
I am installing this software and i will check how it works in my network.
Do you know any cisco commands on routers,switches and cisco asa to do same thing i mean monitoring
users particularly bandwidth utilization.

Munnawer

Hello,
you could try e.g.
Kind redards.
Kai
04-23-2013 10:51 AM
For performance management you can run the open source Cacti on Windows (although most people run it on Linux, as with Nagios mentioned earlier). That will give you high level - e.g. bandwidth used by an interface.
If you want to drill down to see user level utilization you will need to use Netflow on the routers exporting to a collector on a server. What's Up Gold can be a Netflow server. You can also use a free tool like ntop but I don't think it is available on Windows.
