MTU from DC to branch

[vmb01]

A customer has a main  DC and 9 branches . He would like to install NSX-T to have the same L2 segment in all the branches. The question is: does he nedd a 1600 MTU from the main DC to the branches  and frome branch  to branch ?

Hi ,

      Are you planning to use L2VPN for extending the segment across all branches?. Kindly clarify which method you are planning to configure.

Hi 

the customer would like to use a L2 segment not a L2 VPN so the network traffic will be incapsulated from the TEP in the main DC and will be decapsulated from the TEP in the branch.

Hi,

To use overlay, yes you should have a MTU of 1600 or more. Secondly, you have to consider latency between the main DC & the branch as well. Do you. know what is the RTT between the DC & branch offices?

[vmb01]

Hi, I don't know about the RTT latency but which is the maximum latency tolerated?

Between the NSX Manager cluster & Transport nodes, it is 150ms RTT. Kindly refer the configmax for more information
