Which version of OpenWRT are you using ? The default version uploaded doesn't have dhcp enabled and hence it won't respond to ping.

We need a fix as outlined in [1].

    Modify OpenWRT image & rewrite deployment OpenWRT instruction

    This patch adds the customized OpenWRT image that enables DHCP making
    the VNF can be ping. Therefore, the continuously respawning of VNF
    can be fixed.

    This patch also rewrites the instruction of deploying VNF
    based on OpenWRT.
