Show ip bgp summary is an excellent command to check if you have BGP neighbors.

If you like, you can enable MD5 authentication by using the neighbor password command. R2(config-router)# neighbor 192.168.12.1 password MYPASS R1(config-router)# neighbor 192.168.12.2 password MYPASS R2(config)# router bgp 2 If everything goes ok, you should see a message that we have a new BGP neighbor adjacency. This is something you’ll have to do yourself with the neighbor x.x.x.x remote-ascommand. Neighbors are not configured automatically.

Use the router bgp command with the AS number to start BGP. R1(config-router)# neighbor 192.168.12.2 remote-as 2 R2(config)# router bgp 2 Each router has a network on a loopback interface, which we will advertise in BGP. Just two routers and two autonomous systems.

In this lesson I will show you how to configure EBGP (External BGP) and how to advertise networks.
