Lab 9: BGP Hardware Lab - AidanP017/Aidan-NET-330 GitHub Wiki

Purpose

In this lab, we grouped up and configured BGP for a part of a larger network. Specifically, we managed the third router in the AS 1010 network (Vermont-ISP) and established connections between the AS 3033 network (BTV-Router) and AS 2054 network (Pacific-ISP).


Assignments

The following table was used for configurations.

Network Name Network Address Subnet Mask
Vermont-ISP to Pacific-ISP 192.168.1.1/30 255.255.255.252
Vermont-ISP to Burlington-BTV 192.168.2.1/30 255.255.255.252

Consoling Into Switch

Reference the associated section from Lab 4-1 to console into the switch using PuTTY.


Clearing Previous Configurations

After consoling into the router, we first cleared any instances of previous configurations.

write erase
reload

Configuring the Hostname

Next, we started configuring the router by first setting the hostname.

enable
conf t
hostname Vermont-ISP

Configuring the Interfaces

Then, we configured the interfaces in relation to the two autonomous systems.

int fa0/0 (to Burlington-BTV)
ip address 192.168.2.1 255.255.255.252
no shut
exit
int fa0/1 (to Pacific-ISP)
ip address 192.168.1.1 255.255.255.252
no shut
exit

Configuring Routing and BGP

After configuring the interfaces, we configured routing and BGP by first defining the autonomous system (AS) for the router.

router bgp 1010

Then, we configured the BGP peers which corresponded to the neighboring IPs of Pacific-ISP (192.168.1.2/30) and Burlington-BTV (192.168.2.2/30).

neighbor 192.168.1.2 remote-as 2054
neighbor 192.168.2.2 remote-as 3033

Lastly, we configured the BGP advertise networks.

network 192.168.1.0 255.255.255.252 (to Pacific-ISP)
network 192.168.2.0 255.255.255.252 (to Burlington-BTV)

The configurations were saved after establishing them.

end
copy run start

Running the command show run or do show run if in (config) should verify that the FastEthernet ports were properly configured.

After connecting to the other routers, it should be possible to view the routing tables with the BGP routes successfully configured by running the command show ip route or do show ip route if in (config).
