To view the BGP configuration, enter show config in CONFIGURATION ROUTER BGP mode. To view the BGP status, use
the show ip bgp summary command in EXEC Privilege mode. The first example shows the summary with a 2-byte AS
number displayed (in bold); the second example shows that the summary with a 4-byte AS number using the show ip bgp
summary command (displays a 4–byte AS number in bold).

For the router’s identifier, Dell Networking OS uses the highest IP address of the Loopback interfaces configured. Because
Loopback interfaces are virtual, they cannot go down, thus preventing changes in the router ID. If you do not configure
Loopback interfaces, the highest IP address of any interface is used as the router ID.
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.
NOTE:
The showconfig command in CONFIGURATION ROUTER BGP mode gives the same information as the show
running-config bgp command.
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 Networking OS Command Line Interface Reference Guide.
