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.
