Usage Guidelines

As defined by RFC 2338, the device checks the TTL value in received VRRP packets. If the TTL value in a VRRP packet is not 255, the device discards the VRRP packet and generates a log about the VRRP packet error.

On certain networks, especially on a network where the device interoperates 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 VRRP packets.


# Disable the wireless access point from checking the TTL value in VRRP packets.
