CCNA BGP Configuration - An Example

Configuring BGP (Border Gateway Protocol) is a core requirement for the CCNA. Unlike IGP protocols like OSPF or EIGRP, BGP is designed to exchange routing information between different Autonomous Systems (AS).

Here is a standard configuration example for a Basic EBGP (External BGP) peering session between two routers.

Network Topology

  • Router 1 (AS 100): IP 1.1.1.1 on interface G0/0

  • Router 2 (AS 200): IP 1.1.1.2 on interface G0/0


1. Router 1 Configuration (AS 100)

On Router 1, you define the local AS number and identify the neighbor's IP and their AS number.

Plaintext
R1(config)# router bgp 100
R1(config-router)# neighbor 1.1.1.2 remote-as 200
R1(config-router)# network 10.10.10.0 mask 255.255.255.0
  • router bgp 100: Starts the BGP process for AS 100.

  • neighbor 1.1.1.2 remote-as 200: Defines the peer. Since the remote AS (200) is different from the local AS (100), this is EBGP.

  • network: This command tells BGP to advertise the 10.10.10.0/24 subnet. Note: This network must already exist in the router's routing table (via static route or connected interface) for BGP to advertise it.


2. Router 2 Configuration (AS 200)

Router 2 must have a reciprocal configuration pointing back to Router 1.

Plaintext
R2(config)# router bgp 200
R2(config-router)# neighbor 1.1.1.1 remote-as 100
R2(config-router)# network 192.168.1.0 mask 255.255.255.0

3. Verification Commands

Once configured, use these three primary commands to verify the BGP state:

  • show ip bgp summary: The most important command. Look at the State/PfxRcd column. If it shows a number (e.g., 1), the session is up. If it says Active or Idle, the session is down.

  • show ip bgp: Shows the BGP table (all paths learned via BGP).

  • show ip route bgp: Shows only the best BGP paths that have been installed into the main routing table.


Key CCNA Tips for BGP

  • BGP Split Horizon: In IBGP (Internal BGP), a router will not advertise a route learned from an IBGP peer to another IBGP peer to prevent loops.

  • Next-Hop Self: When passing EBGP routes into an IBGP network, routers often need the command neighbor [IP] next-hop-self because the next-hop IP doesn't change by default when moving between AS boundaries.

  • Administrative Distance: EBGP has an AD of 20, while IBGP has an AD of 200.

CCNA IOS - Configuring Console Password

 Configuring a console password on a Cisco IOS router is a fundamental security step to prevent unauthorized physical access to the device. Here's how you do it:

Command Steps:

  1. Enter Global Configuration Mode: You start by entering the global configuration mode from the privileged EXEC mode.

    Cisco CLI
    Router> enable
    Router# configure terminal
    Router(config)#
    
  2. Access the Console Line: You need to specify that you are configuring the console line (line 0).

    Cisco CLI
    Router(config)# line console 0
    Router(config-line)#
    
  3. Set the Password: This command sets the password for console access.

    Cisco CLI
    Router(config-line)# password <your_console_password>
    

    Replace <your_console_password> with the password you want to set.

  4. Enable Login: This command tells the router to require a password for console access. Without this command, the password won't be enforced.

    Cisco CLI
    Router(config-line)# login
    
  5. Set an Executive Timeout (Optional but Recommended): This command automatically logs out an inactive console session after a specified time. This is good practice to prevent someone from leaving a console session open.

    Cisco CLI
    Router(config-line)# exec-timeout <minutes> <seconds>
    

    Example: exec-timeout 10 0 (logs out after 10 minutes of inactivity)

  6. Exit Configuration Modes:

    Cisco CLI
    Router(config-line)# exit
    Router(config)# exit
    Router#
    
  7. Save the Configuration: To ensure the password persists after a router reload, you must save the running configuration to the startup configuration.

    Cisco CLI
    Router# write memory
    

    Or the shorter command:

    Cisco CLI
    Router# copy running-config startup-config
    

Example Configuration Script:

Cisco CLI
Router> enable
Router# configure terminal
Router(config)# line console 0
Router(config-line)# password MyC0ns0leP@ssw0rd!
Router(config-line)# login
Router(config-line)# exec-timeout 10 0
Router(config-line)# exit
Router(config)# exit
Router# write memory

Verification:

To test if the console password is set, save the configuration, and then try to log in to the console again (either by physically disconnecting and reconnecting the console cable, or by reloading the device if it's a lab environment). You should be prompted for the console password before getting to the user EXEC mode (Router>).

Important Considerations:

  • Strong Passwords: Always choose a strong, complex password that combines uppercase and lowercase letters, numbers, and special characters.

  • Security: This only protects physical access. For remote access (Telnet/SSH), you need to configure VTY passwords as well.

  • "login local" vs. "login": If you configure local usernames and passwords (e.g., using username <name> password <password> or username <name> secret <secret>), you would use login local on the line. However, for a simple console password, login is sufficient.
