Use the show lldp neighbors and show ip bgp summary commands on the DCI switches to ensure they are configured correctly. This section shows the commands and output for each DCI switch.
The show lldp neighborscommand is used to verify all connections are up and connected to the correct ports.

Verify BGP is configured properly on the DCI switches by running the show ip bgp summary command at the CLI of each DCI switch. Use the output to confirm the IP addresses and AS numbers are configured correctly and the sessions between DCI switches are up. Sessions are up if the up time is displayed in the Up/Down column.
Note: BGP sessions between the DCI and SFS leaf switches, AS numbers 65011 and 65015, will not be up until the SFS fabric interconnects are configured in the next chapter.
