    Hi

    controllers version 8.6.0.2

     The composition is standalone / standby. vrrp

     

    In what cases can the logo below occur?

    The backbone switch has no Duplicate message on the HPE 5510.

    Please share the vrrp configuration from both standalone and standby controllers.

    What is the device 00:1a:1e:02:04:78? 

     

    Also, how are you doing IPv6 address assignment for this network? The hardware mac is seen with an IPv6 address of 2001::1 as well as an IPv4 to IPv6 mapped address using the ::ffff:0:0/96 space.

    Hi

     

    00:1a:1e:02:04:78 -> Master(standalone) controller

     

    standalone IPv6 is disabled

    The standby is IPv6 enabled.

     

    Thank you.

    Why is IPv6 configured on the backup? The backup and master configurations should be mirrored. The errors you are seeing look to be related to the IPv6 configuration, which also does not appear to be correct. If IPv6 is required, we'll need to dig into the addressing scheme to be used as the current assignments do not appear to be valid.
