Enabling BGP
By default, BGP is not enabled on the system. Dell Networking OS supports one autonomous system (AS) and assigns the AS number
(ASN).
To establish BGP sessions and route traffic, configure at least one BGP neighbor or peer.
In BGP, routers with an established TCP connection are called neighbors or peers. After a connection is established, the neighbors
exchange full BGP routing tables with incremental updates afterward. In addition, neighbors exchange KEEPALIVE messages to maintain
the connection.
In BGP, neighbor routers or peers can be classified as internal or external. External BGP peers must be connected physically to one another
(unless you enable the EBGP multihop feature), while internal BGP peers do not need to be directly connected. The IP address of an EBGP
neighbor is usually the IP address of the interface directly connected to the router. First, the BGP process determines if all internal BGP
peers are reachable, then it determines which peers outside the AS are reachable.
NOTE:
for enabling BGP routers are found at the end of this
chapter.
