Interesting...we have not seen that problem with IPv6 and CARP. I just looked and the backup is showing Backup for all IPs.
I do occasionally, like after our 2.3.2 to 2.3.3_1 upgrade, where one IP does get stuck as Master on the backup after the primary is updated and restarts. I am fairly certain it was an IPv4 address though, and is not a new issue. Restarting fixes it. Hamid, are you saying you have two issues, that IPv6 is not being synced and that DHCPv6 is not being synced? We aren't using DHCPv6 but have not seen any issues with IPv6 and CARP. IPv6 connectivity shouldn't be related to whether DHCPv6 is running, as long as the PCs have addresses...? -- Steve Yates ITS, Inc. -----Original Message----- From: List [mailto:[email protected]] On Behalf Of Jochen Becker Sent: Wednesday, March 22, 2017 1:25 PM To: hamid ashraf <[email protected]>; pfSense Support and Discussion Mailing List <[email protected]> Subject: Re: [pfSense] IPv6 (CARP and DHCPv6 failover) Hi Hamid, can you check whether your IPv6 CARP Addresses are in agood condition after 10-15 minutes of uptime? I have a problem with multiple setups where CARPv6 changes to dual master after 10 minutes. IPv6 connectivity is nearly impossible with that setup. However IPv4 and CARP with v4 are working as they should. Those problems appeared short after the update to 2.3.3p1.
