8.2 Example 2 validation
In addition to sending traffic between hosts, the configuration shown in Figure 15 can be validated with the
commands shown in this section. For more information on commands and output, see the Command Line
Reference Guide for the applicable switch (links to documentation are provided in Appendix C).
Command and output examples are provided for one spine and one leaf. Command output on other switches
is similar.
8.2.1 show ip bgp summary
When BGP is configured, this command shows the status of all BGP connections. Each spine has four
neighbors (the four leafs) and each leaf has two neighbors (the two spines). On Dell EMC switches, this
command also confirms BFD is enabled on the 6th line of output.
