To view the status of BGP neighbors, use the show ip bgp neighbors command in EXEC Privilege mode
as shown in the first example. For BGP neighbor configuration information, use the show running-config
bgp command in EXEC Privilege mode as shown in the second example.
The following example displays two neighbors: one is an external internal BGP neighbor and the second one
is an internal BGP neighbor. The first line of the output for each neighbor displays the AS number and states
whether the link is an external or internal (shown in bold).
The third line of the show ip bgp neighbors output contains the BGP State. If anything other than
ESTABLISHED is listed, the neighbor is not exchanging information and routes. For more information about
using the show ip bgp neighbors command, refer to the Dell Nettworking OS Command Line Interface
Reference Guide.
NOTE:
The showconfig command in CONFIGURATION ROUTER BGP mode gives the same information
as the show running-config bgp command.
