Hi all.
There’s no network connection between host and dpu after installation in embedded mode.
Here’s my conguration.

Try assign ip to interfaces?
According to this note Configuring NVIDIA BlueField2 SmartNIC | Better Tomorrow with Computer Science

Thanks for reply.
IP has already been assigned to ens1f0(172.16.10.1, host side) and enp3s0f0s0(172.16.10.2 dpu side)
