A DHCP relay that has more than one poolmember configured, forwards requests to all of them as expected. However, if there is a constant flow of DHCP traffic from the client, and monitors change the state of these poolmembers, a poolmember that was down, does not get traffic when it comes up, and a poolmember that goes down, still receives forwarded DHCP traffic.
Pool members are not used if they become active after sessions are created, or remain in use when they are inactive.
Pool members states are changed after sessions are created.
After pool members state are changed, delete all the sessions and re-create them.
Pool members now have traffic correctly forwarded to them if their status changes (that is, they become active/inactive) after sessions are created.
