unable to establish east-west communication using NSX-T

[bhards4]

Hi All,

I have setup lab of NSX-T 2.4 where Im trying to communicate East-West communication but after multiple attempt Im unable to establish the communication amount 2 diffrent subnet VM's

My lab environment

vmware workstation 15.5.0

NSX-T 2.4

ESXi 6.7

vCenter 6.7

Created 3 network on Workstaton 15.5.0

vmnet-8 ( For management Network) 192.168.0.x

vmnet-0 (vmnetwork) 192.168.1.x)

vmnet-1 (vmnetwork) 192.168.2.x)

I have created T-1 Gateway and 2 segments

Advertise Route (All Static Routes & All Connected Segments & Service Ports) on T-1 Gateway.

Seg-1 subnet 192.168.1.1

Seg-2 subnet 192.168.2.1

Created 2 VMs on vCenter and allocated IP

vm1 192.168.1.2

vm2 192.168.2.2

Added the segment on the VM network as per the IP address.

Now when I try to ping vm2 ip from vm1 VM, I'm unable to ping but only able to ping the default gateways of both the segments.

Please let me know if I missed somewhere.

You keep asking for a "solution" yet the problem is not clear. That's why we're trying to determine what doesn't work. When you say "no, I cannot ping between TEPs" and then you later say "yes, I can ping between TEPs" you are the one playing "quiz quiz show" with us. Without systematically testing what can cause your failure (such as no TEP-TEP communication), we cannot offer a solution for you.

ok,

let me brief you again for your convinience

Im using VMware workstation 15.5 as the underlay infrasructure.

1) I have 2 ESXi host with IP 192.168.0.111 and 192.168.0.112

2) 2 segments created web (192.68.1.1/24 and 192.168.2.1/24)

3) TEP pool is in 192.168.0.131.-140

TEP IP assigned on ESXi are 192.168.0.131 and 192.168.0.132

Now as you have asked whether you were able to ping TEP on both the ESXi or not, then the ans is yes
