The above information indicates that in standby group 1 Router A is the master,
Router B is the backup and the host with the default gateway of FE80::10 accesses
the Internet through Router A; in standby group 2 Router A is the backup, Router
B is the master and the host with the default gateway of FE80::20 accesses the
Internet through Router B.

Multiple standby groups are commonly used in actual networking. In IPv6
network, you need to manually configure the default gateway for a VRRP standby
group to share load.
Symptom 1:
The console screen displays error prompts frequently.
Analysis:
This error is probably due to the inconsistent configuration of the other router in
the standby group, or that a device is attempting to send illegitimate VRRP
packets.
Solution:
In the first case, modify the configuration.
■
In the latter case, you have to resort to non-technical measures.
■
Symptom 2:
Multiple masters are present in the same standby group.
Analysis:
If presence of multiple masters only lasts a short period, this is normal and
■
requires no manual intervention.
