Hello everyone!
I created one VN and 2 VM in it. Ping was success, but other traffic didn't transmit. FW is disabled, VN config by default without policy, SG allow all traffic. What can be wrong?
TF v5.1 (use contrail-helm-deployer)

I gues that core ussue related to mtu, what mtu do i need to set on interfaces(VM,Host)? Now, all interface have mtu = 1500.

On Host its better to enable jumbo frames.
You can also try ICMP with packet size of 1472 with DF flag set and see if its going through.
ping -Mdo -s 1472 <distip>
