Configure BGP on Your Router

After establishing your BGP session on zenConsole, to enable BGP interconnect, you need to configure BGP on your router.

Note

• Make sure you are familiar with BGP configuration and consult professionals if necessary.

• BGP configuration may vary depending on router models and the version of the router's operating system (IOS), refer to your router's manual if you need.

Procedures

1. Access Router Configuration Mode Log in to your router and access the configuration mode. This is typically done through a command-line interface (CLI) using SSH, Telnet, or a console connection.

2. Enter BGP Configuration Mode Once in the router's configuration mode, enter BGP configuration mode by typing:

   router bgp <your-as-number>

   Replace <your-as-number> with your Autonomous System Number (ASN).

3. Configure BGP Neighbor Relationship

   Configure BGP neighbor relationships to establish connections with other routers. Use the following command:

   neighbor <neighbor-ip-address> remote-as <neighbor-as-number>

   Replace <neighbor-ip-address> with the IP address of your BGP neighbor, that is the Peer IP in BGP Session Details; and <neighbor-as-number> with their ASN, that is the Peer ASN (21859).

4. Configure BGP Route Policies

   • Create a route policy: route-map <route-map-name> permit 10

   • Match routes: match ip address 1

5. Activate BGP Neighbor Relationships Once you have configured BGP neighbor relationships and route policies, activate the BGP neighbor relationships using the command:

   neighbor <neighbor-ip-address> activate

   Replace <neighbor-ip-address> with the IP address of your BGP neighbor, that is the Peer IP in BGP Session Details.

Example

pythonCopy coderouter bgp 65000
neighbor 10.0.0.1 remote-as 21859
route-map to-as21859 permit 10
  match ip address 1
neighbor 10.0.0.1 activate

6. Save Configuration After configuring BGP, make sure to save the configuration changes to the router's running configuration. Use the command:

   arduinoCopy codewrite memory

   or

   arduinoCopy codecopy running-config startup-config

   This ensures that the configuration changes are retained even after a reboot.

7. Verify Configuration Use various show commands (e.g., show ip bgp, show ip bgp neighbor) to verify that BGP has been configured correctly and is operational.
