Switch B is the backup and the host with the default gateway of FE80::10 accesses

Multiple standby groups are commonly used in actual networking. In IPv6
network, you need to manually configure the default gateway for VRRP standby
group to share load.
Troubleshooting VRRP Symptom 1:

Analysis:
This error is probably due to the inconsistent configuration of the other device in
the standby group, or that a device is attempting to send illegitimate VRRP
packets.
Solution:
■ In the first case, modify the configuration.
