55 VCF on VxRail Multirack Deployment using BGP EVPN

9 Validate connectivity between virtual machines

This chapter covers a quick validation of the entire solution. A combination of ping and traceflow are used

between a combination of three virtual machines and a loopback interface. Two of the VMs are associated

with one segment, Web, and the other VM is associated with the segment, App. The loopback interface

represents all external networks.

Figure 29 shows the three virtual machines, Web01, Web02, and App01, are running on two separate hosts.

Web01 and Web02 are associated with the Web segment, and App01 is configured in the App segment.

Web01 is in rack 1, and the other two virtual machines are in rack 2. In this test, only two of the four VxRail

nodes are used. The router ID for Spine02, 10.0.1.2/32, is used to test connectivity from the NSX-T overlay to

the switch underlay.

Validation topology

The tests that are performed are:

• Ping from Web01to Web02

• Ping from Web01 to App01

• Ping from Web01 to Router ID on Spine02

• Ping from App01 to Router ID on Spine02

• Traceflow from App01 to Router ID on Spine02

Note: The steps required to create the two segments are beyond the scope of this document. See the NSX-T

Administration Guide: Segments.
