The following example shows the
show ip bgp summary
command output (4–byte AS number displays).

R2#
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 .
The following example shows the
show ip bgp neighbors
command output.
