Hello Everyone,
I have been facing issues with the transport node on Host and Edge, after successfully adding the nodes, the Tunnel status is down, due to which the transport node throws error status in Dashboard of NSX-T. FYI Screenshot
Is there anyone who has come across the similar issue? and resolved it.
Regards,

Do you have any active VMs connected to logical switches on that node yet? The Geneve tunnels used by NSX-T don't get established until there's a VM connected to a logical switch on the given node so while it can be kind of misleading, it'll show the tunnel status as "down" until it actually has a reason to form the tunnel.

Edge transport node down is also because no VMs? Or just will cause host TN down if no VMs?
Edge node TNs will show the tunnel as "up" once you've got a router deployed to them. Otherwise, they show the status as "unknown".
Thanks. Do you have any ideas why the bond status in TN is unknown or down?

Hi,
I had a doubt, since its the first time, i am setting up NSX-T, i am not able to establish the connection between Tier0 and Tier1 even after the Linked Ports are set, is it because of the Transport Node, since there is no Transport Node attached to Tier1 Router.
please do share, if you have any documents to troubleshoot this scenarios.
This appears to show that it is connected so when you say you can't establish the connection, are you referring to end to end reachability of networks behind the Tier 1 router? If so, be aware that by default the T1 router doesn't advertise any of the connected networks upstream so the first thing to check would be to ensure that you've enabled route advertisement under the "routing" tab of the Tier 1 router so that it looks like this:
Yes, i have enabled all this, still i m not able to reach tier1 from tier0, I have also added a couple of static routes on Tier0 since Tier0 uplink is on different subnet, the Intra Tier0 to Tier1 is on a different subnet, which is the Computer generated switch with 100 series and Tier1 is on a different subnet.
Even after applying so many Static routes to achieve Connectivity, it fails to ping the Tier0 Intra subnet and Tier1 subnet.
On the Edge Console, when you access the Tier0 and get routes, the Output is only via 192.168.x.x
How do i confgiure this, so that i will be able to communicate
Please give your inputs
Hi Boby,
I am experiencing something different. The moment i connect VM to logical segment my tunnel get down. BGP gets discuonncted to physical router. Error has been given below
escription: The overall tunnel status of Edge node f5384406-bfe3-42c0-b967-8495ce6a0212 is down.
Recommended Action: Invoke the NSX CLI command `get tunnel-ports` to get all tunnel ports, then check each tunnel's stats by invoking NSX CLI command `get tunnel-port stats` to check if there are any drops. Also check /var/log/syslog if there are tunnel related errors.
Which version NSX-T and vCenter are you using ?
Could you share with us your topology ?
So I'll ask a few questions to hopefully get all the answers in one spot to make this a little easier to troubleshoot.
This link may assist in troubleshooting and working out any TEP addressing issues https://www.lab2prod.com.au/2020/11/nsx-t-inter-tep.html.
I would also remove all the additional static routes you added as they generally aren't need for an out of the box deployment.
The more clearer and detailed you can be with these answers, the easier it will be to diagnose and resolve your issue.
Cheers
