Usage Guidelines

The device checks the TTL value in received VRRP6 Advertisement packets. If the TTL value of a VRRP6 Advertisement packet is not 255, the device discards the packet.

On certain networks, especially on a network where the device interworks with non-Huawei devices, valid packets may be discarded if TTL check is enabled. You can configure the device not to check the TTL value in VRRP6 Advertisement packets.
