Hi Abdul500,
To prevent VRRP status inconsistency, Huawei develops the VRRP Group Management Protocol (VGMP) based on VRRP. A VRRP management group established based on VGMP manages the status of each VRRP backup group in a unified manner. This ensures that interfaces on a router are in the active or standby state at the same time, ensuring that the VRRP status of the routers is consistent.
Huawei Redundancy Protocol (HRP) is carried over VGMP packets to back up key configuration commands and session table status information between the master and backup devices.
VGMP and HRP are Huawei proprietary protocols that run on firewalls.
