Severity: 3-Major
vCMP: VLAN failsafe does not trigger on guest due to IPv6 link-local neighbor discovery traffic from host.
Since the heartbeat messages going over IPv6 link-local addresses continue to be successfully passed from host to guest, VLAN failsafe does not trigger if a downstream router or switch goes down that's connected to the VLAN.
vCMP host configured, VLAN failsafe enabled on a VLAN, one or more VCMP guests enabled that use that VLAN
If you are able to, disabling IPv6 on the host will allow VLAN failsafe to work as expected.
