58 Dell EMC Networking with Isilon Front-End Deployment and Best Practices Guide | version 1.08 ValidationIn addition to sending traffic between hosts, the configuration shown in both topologies can be validated withthe commands shown in this section. The validation for the layer 2 topology will only reference sections 8.1.3– 8.1.9 for OS10EE and sections 8.2.3 – 8.2.8 for OS9.Note: For more information on commands and output, see the Command Line Reference Guide for theapplicable switch (links to documentation are provided in Appendix B.Command and output examples are provided for one spine and one leaf. The OS9 section will only cover thevalidation of a single leaf as the spine layer is running OS10EE. Command output on other switches is similar.8.1 OS10EE Validation commandsThis section will cover the validation of the S4048-ON leaf switches that are running OS10EE as well theZ9100-ON spine switches.Command and output examples are provided for one spine and one leaf. Command output on other switchesis similar.8.1.1 show ip bgp summaryWhen BGP is configured, this command shows the status of all BGP connections. Each spine has fourneighbors (the four leafs) and each leaf has two neighbors (the two spines).Z9100-Spine1# show ip bgp summaryBGP router identifier 10.0.1.1 local AS number 64601Neighbor AS MsgRcvd MsgSent Up/Down State/Pfx192.168.1.1 64701 2119 2146 00:55:27 3192.168.1.3 64702 2101 2113 00:54:38 3192.168.1.5 64703 2291 2322 01:37:49 3192.168.1.7 64704 2290 2310 01:37:36 3S4048-Leaf1#show ip bgp summaryBGP router identifier 10.0.2.1 local AS number 64701Neighbor AS MsgRcvd MsgSent Up/Down State/Pfx192.168.1.0 64601 131660 131649 3d:21:49:06 10192.168.2.0 64602 131685 131625 3d:21:49:04 108.1.2 show ip route bgpOn switches with BGP configured, this command is used to verify the BGP entries in the Routing InformationBase (RIB). Entries with multiple paths shown are used with ECMP. The two server networks in this example,10.60.1.0 and 172.16.1.0, each have two paths from Z9100-Spine1, one through each leaf.The first set of routes with a subnet mask of /32 are the IPs configured for router IDs.
