I have 2 logical in a datacenters is a cross vcenter environment.The segregation for datacenters is logical but the physical devices(Nexus,servers,firewall) resides on the same site/location/racks.
Primary Site - Vcenter 6.7
Secondary site - Vcenter 6.7
NSX version - 6.4.3
I have created a universal logical switch of network 10.1.80.0/24 connected with the universal DLR.
In primary site i have been running the workload for the last 6 months and all the communication is working fine.
Recently we decided to optimize the use of secondary site and deployed few vmware applications(OVF based) onto the stretched vxlan(10.1 .80.0/24) networks on secondary site.
The issue is I am not able to open the VAMI page of my appliances from my primary site vxlan/vlans to the secondary site stretched vxlan(10.1.80.0/24).
Though I can ping/telnet the servers from my primary site to secondary site server but the application refuses to connect.
As per the attached Diagram VM A is not able to access the URL/Applications/vami pages for VM B and vice versa.
Although VM A can ping/telnet to VM B and vice versa.
Physical firewall is not involved in the entire communication.
NSX firewall/distributed firewalls are disabled.
Ping/telnet is absolutely working fine hence no routing issues.
Attached the logical Diagram.
Does anybody else have faced such weird issue? Or am i missing anything?
are you sure that MTU is 1600 across site??
