Broadcast URI not set for Shared networks when IP(v4) range not provided

[Pearl1594]

ISSUE TYPE

• Bug Report

COMPONENT NAME

Network Setup / VM deployment

CLOUDSTACK VERSION

4.19.1.3 (But may be observed in all versions)

CONFIGURATION

OS / ENVIRONMENT

Agnostic of OS

STEPS TO REPRODUCE

1. Create a network offering for Shared network with specifyVlan = false and no services ; enable the network offering
2. Create a shared network using this offering and provide only IPv4 gateway and netmask (no IP range provided)
3. Attempt deploying VM with the network created in step 2

EXPECTED RESULTS

Should check if required IP range is provided

ACTUAL RESULTS

Fails to create network due to an NPE (cause because no validations are made for the IPv4 range)
