VRRP for sub-interface

Hi Sprout,

When VRRP is enabled on a Dot1q termination sub-interface, VRRP Advertisement packets need to be encapsulated with a VLAN tag so that VRRP Advertisement packets can be transmitted in the VLAN and negotiation can be performed between VRRP-enabled devices. 

The dot1q vrrp command enables a Dot1q termination sub-interface to add a specified VLAN tag to VRRP Advertisement packets or remove a specified tag from VRRP Advertisement packets.

configuration:

[R1-GigabitEthernet0/0/1.10]dot1q vrrp vid 10

By the way, if the vlan-type dot1q sub-interface instead of the Dot1q termination sub-interface is used, you do not need to run this command.

For the differences between the two encapsulation modes, see https://forum.huawei.com/enterprise/en/dot1q-termination-vs-vlan-type-dot1q/thread/570035-863.

Hi,

Thanks, after the command is added, the vrrp group status is normal.
