BGP - wAlber47/Tech-Journal GitHub Wiki
Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.
- Define the instance for the router, this should be based off of the AS number.
(config)# router bgp <AS-#>
- Identify the neighbors of the router. These are all the routers that the one you are configuring needs to communicate with. Referred to as a peer.
(config-router)# neighbor <ip-of-peer> remote as <AS-#-of-peer>
- Advertise the networks that your AS has. This is the networks that are in your area.
(config-router)# network <network-address> mask <subnet-mask>
- In terms of this lab, remember to configure BGP on the Foster202 AS.
- Make sure you use the network address when defining your networks, and use the IP Address when setting your peers.
