Hi, i have a problem with DHCP on all VLANs just after update MXes (to 250 in HA) from 14.53 to 15.42.1. Both MXes were working as DHCP server in all VLANs and till the upgrade all was ok. Just after update, i got: DHCP problem extra: no_offers_received, vap: 0, vlan: 248 Tried to restart MXes, disable/enable DHCP etc but without any results. Finally helped downgrade. Do you know what might be the reason? Is there a special configuration to be done after the upgrade?
