23.1 Legacy Series / multiple DHCP6c renewals on the same interface
« on: July 03, 2023, 03:13:28 pm »
Greetings,
I noticed this behavior in the logs starting around 23.1.8. I'm getting multiple dhcp6c renewals within seconds of each other for my WAN interface. I would expect to see one renewal but seeing two of them back to back like this seems like something is wrong? Is anyone else seeing these too?
Router settings:
WAN interface configured with DHCP/DHCPv6
LAN interface set to Track DHCPv6 to delegate a prefix to LAN clients
Example of what I'm seeing in the logs:
