Hi Ramesh, Where did you configured the public IP whcih given by your ISP? If you are full with interfaces then try to configure the public IP as a secondary IP on the interface to which your ISP link connected. Once you configured the poublic IP on interface then you can configure NAT as well PAT. Let me know if you need any configuration help. Another question is why you used to interfaces for LAN only? what is the purpose? what you are looking to achieve? Please rate the helpfull posts. Regards, Naidu.

Two BGP routers become neighbors after the routers establish a TCP connection between each other. The TCP connection is essential in order for the two peer routers to start the exchange of routing updates. After the TCP connection is up, the routers send open messages in order to exchange values. The values that the routers exchange include the AS number, the BGP version that the routers run, the BGP router ID, and the keepalive hold time. After the confirmation and acceptance of these values, establishment of the neighbor connection occurs. Any state other than Established is an indication that the two routers did not become neighbors and that the routers cannot exchange BGP updates. Issue this neighbor command to establish a TCP connection: neighbor ip−address remote−as number Please rate the helpfull posts. Regards, Naidu.

Well, BGP goes through six states to establish an adjacency. Idle: Incoming connections are refused, and the system gets ready to start speaking BGP. After this is done (by way of a Start event), move to Connect. Connect: A connection is made to the peer. Send a BGP OPEN message, and go to OpenSent. Active: A connection comes in from a peer. Send a BGP OPEN message, and go to OpenSent. OpenSent: Wait for an OPEN message from the peer. When received, send a KEEPALIVE and go to OpenConfirm. OpenConfirm: Wait for the KEEEPALIVE from the peer, and then move to Established. Established: Bidirectional communication is established. Start sending UPDATE and KEEPALIVE messages as required. Please rate the helpfull posts. Regards, Naidu.

Hi, There are many ways to recover the password. One is see the below link.. http://www.esds.co.in/forum/f5/steps-password-recovery-cisco-2960-switch-339/ Second one is... Step 1. Connect a terminal or PC with terminal-emulation software to the switch console port. Step 2. Set the line speed on the emulation software to 9600 baud. Step 3. Power off the switch. Reconnect the power cord to the switch and within 15 seconds, press the Mode button while the System LED is still flashing green. Continue pressing the Mode button until the System LED turns briefly amber and then solid green. Then release the Mode button. Step 4. Initialize the Flash file system using the flash_init command. Step 5. Load any helper files using the load_helper command. Step 6. Display the contents of Flash memory using the dir flash command: The switch file system appears: Directory of flash: 13 drwx 192 Mar 01 1993 22:30:48 c2960-lanbase-mz.122-25.FX 11 -rwx 5825 Mar 01 1993 22:31:59 config.text 18 -rwx 720 Mar 01 1993 02:21:30 vlan.dat 16128000 bytes total (10003456 bytes free) Step 7. Rename the configuration file to config.text.old, which contains the password definition, using the rename flash:config.text flash:config.text.old command. Step 8. Boot the system with the boot command. Step 9. You are prompted to start the setup program. Enter N at the prompt, and then when the system prompts whether to continue with the configuration dialog, enter N. Step 10. At the switch prompt, enter privileged EXEC mode using the enable command. Step 11. Rename the configuration file to its original name using the rename flash:config.text.old flash:config.text command. Step 12. Copy the configuration file into memory using the copy flash:config.text system:running-config command. After this command has been entered, the follow is displayed on the console: Source filename [config.text]? Destination filename [running-config]? Press Return in response to the confirmation prompts. The configuration file is now reloaded, and you can change the password. Step 13. Enter global configuration mode using the configure terminal command. Step 14. Change the password using the enable secretpassword command. Step 15. Return to privileged EXEC mode using the exit command. Step 16. Write the running configuration to the startup configuration file using the copy running-config startup-config command. Step 17. Reload the switch using the reload command. Please rate the helpfull posts. Regards, Naidu.

Hi, There are many aspects to block one host to get internet access. One you can define one accesslist and apply that to outbound interface. Second if you have global NAT cnfigured on your router then in that pool (could be route-map) you need to block this host. Example for the first one... ip accesslist ex outboudaccess deny ip host 10.38.5.140 any permit any any int gi0/0 ip access-group outboudaccess in Exampel for the second one... ip nat inside source route-map nonat pool nonat mapping-id 1 overload ip access-list ex NONAT deny ip host 10.38.5.140 any permit ip any any Please rate the helpfull posts. Regards, Naidu.

Hi Dinesh, As you may know that there are 5 types of OSPF packets there are.... Hello packet Database Descriptor packet Link State Request packet Link State Update packet Link State Acknowledgment packet In that hello is a protocol used by OSPF routers to find the neighbor devices and it also used to establish neighbor relations ships in between OSPF routers. And Hello Packet contains the following data: 1. ROUTER ID = Router ID, this is a 32-bit number that is unique to this router 2. HELLOS & DEAD INTERVALS = Hello and dead interval Period of time between hellos and the dead timer, these values must match between two routers becoming neighbors 3. NEIGHBOUR LIST = Is a List of neighbor Router Ids that this router sees as their neighbor 4. AREA ID = Area ID Area number, this value must be identical between two routers becoming neighbors 5. ROUTER PRIORIY = Router Priority of this interface, the router advertising the highest priority is elected the designated router during the DR/DBR election process. 6. ROUTER ID = The Router ID of who this router believes is the DR and BDR IP address of designated routers 7. AUTHENTICATION = If you have authentication set it is important that the Password matches between the two routers becoming neighbors. 8. STUB AREA FLAG = If the routers becoming neighbors are in a Stub Area, then the Stub Area Flag must be set Hope the above make you clear understand about OSPF packets. Please rate the helpfull posts. Regards, Naidu.

Hi Joe, Each other are there for different aspects. iBGP is to serve within AS where eBGP is to serve between different autonomous system. If an AS has multiple BGP speakers, the AS can serve as a transit service for other ASs. Please rate the helpfull posts. Regards, Naidu.

Hi, As per the example config I provided in my last post. You need to apply the route-map to which vlan traffic you want to send the specific firewall. Still if you are not sure to where apply the route-map, post here your config so that I can advice you on that where to apply exactly. Please rate the helpfull posts. Regards, Naidu.
