BGP Lab/Assignment 3 - Part 1

Each group is to configure one router so that it participates in the following simple BGP network. The routers will speak BGP to one another via interfaces 0/0 and 1/0. At this stage no interior routing protocol will be configured.

The physical layout of the network is as follows:

BGP peering sessions are to be established as follows:

The remaining interfaces are to be assigned addresses from the table below:

Interface	Router 1	Router 2	Router 3	Router 4
1/1	192.168.11.254/24	192.168.21.254/24	192.168.31.254/24	192.168.41.254/24
1/2	192.168.12.254/24	192.168.22.254/24	192.168.32.254/24	192.168.42.254/24
1/3	192.168.13.254/24	192.168.23.254/24	192.168.33.254/24	192.168.43.254/24

Laboratory Tasks

1. Configure each router interface with the appropriate IP address.
2. Disable telnet access to your router on all network interfaces.
3. Configure BGP and establish sessions with the appropriate peers.
4. Enter the appropriate commands so that BGP advertises all directly connected networks.
5. Ensure that your router is learning routes from your peers.
6. Ensure that other routers are learning routes that are being advertised from your router.
7. Connect your Linux workstation into your hub and configure it with an appropriate IP address. Verify that you can ping another group's workstation (or at least one of their "internal" router interfaces).
8. Record your router's running configuration - you'll need this for the next lab! You might also want to save the current configuration as the startup configuration...
9. Try to identify the AS Path that your router uses for each other Autonomous System.

Some commands to try:

show ip route
show ip bgp
show ip bgp summary
show ip bgp neighbor
show ip bgp paths
show ip bgp [network address]
