My Mikrotik 850Gx4 log is flooded with "pool6 refused acquire: bad preferred prefix! (1)".
It make impossible to view any usefully log entry, as the error repeat itself every second.
Received addresses are /64 prefix.
Re: DHCP v6 error
This is a dhcpv6-pd server or client?
post: an export of the dhcpv6 - pd server / client and post an export of the ipv6 pools.

Re: DHCP v6 error
Hello!
I observed that ISP prefix is different from pool prefix (56 vs 64), but both are acquired from ISP. By delete bindings error is gone.
I am new to ipv6 and it seems to me that DHCPv6 server is somewhat limited on mikrotik, compared to ipv4.
How can I make static leases on ipv6 like on ipv4 ?
Sorry, I forgot DHCP client:
Code: Select all
/ipv6 dhcp-server print
Flags: D - dynamic, X - disabled, I - invalid
# NAME INTERFACE ADDRESS-POOL PREFERENCE LEASE-TIME
0 DHCP_LAN_ipv6 bridge static-only 255 3d
