This is change taken as part of the HLD: sonic-net/SONiC#1470 and this is a follow up on the PR #16827 where in the docker-dhcp we pick the value of primary gateway of the interface from the VLAN_Interface table which has "secondary" flag set in the config_db Microsoft ADO (number only): 16784946 How did I do it - Changes in the j2 file to add a new "-pg" parameter in the dhcpv4-relay.agents.j2, the ip would be retrieved from the config db's vlan_interface table such that the interface which are picked will have secondary field set. - Changes in isc-dhcp to re-order the addresses of the discovered interface and which has the ip which has the passed parameter.

Microsoft ADO (number only): 16784946 How I did it Made changes in the minigraph.py to parse the xml entry and add the parsed value to the config db How to verify it Added python tests in the sonic-config-engine folder to test the config db entries.
