kea-dhcp4 can't offer ip reserved.
subnet : 192.168.0.0/24 reservation1 : mac(aa:aa:aa:aa:aa:aa) ip(192.168.0.11) reservation2 : mac(bb:bb:bb:bb:bb:bb) ip(192.168.0.12)
reservation1 has router option(3) 192.168.0.3 reservation2 has no options.
I used mysql for hosts reservation.
kea-dhcp4 responses to reservation1 but fail to response to reservation2 somtimes.
The Failure log is 'preparing on-wire-format of the packet to be sent failed DHCPv4 Option4AddrLst 3 is too big.At most 255 bytes are supported.'
In packets debug log, kea-dhcp4 try to response to reserve2 with router option(value is 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 ....... maybe 2048~4096byte)
