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.
