Multiple Masters Coexist in a VRRP Group
Fault Symptom
Multiple masters exist in a VRRP group for a long period of time.
Procedure
- Ping masters to check network connectivity between masters.
- If the ping operation fails, check whether the network connection is correct.
- If the ping operation is successful and the TTL value of the ping packet is 255, go to step 2.
- Run the display vrrp protocol-information command in any view to check whether the VRRP version on each master is compatible with the mode in which VRRP Advertisement packets are sent.
- If the version is incompatible with the mode, run the vrrp version { v2 | v3 } command in the system view to change the version.
- If the version is compatible with the mode, go to step 3.
- Run the display vrrp virtual-router-id command in any view to check whether the masters use the same virtual IP address, interval at which VRRP Advertisement packets are sent, authentication mode, and authentication key.
- If the configured virtual IP addresses are different, run the vrrp vrid virtual-router-id virtual-ip virtual-address command to set the same virtual IP address.
- If the intervals are different, run the vrrp vrid virtual-router-id timer advertise advertise-interval command to set the same interval.
- If the authentication modes and authentication keys are different, run the vrrp vrid virtual-router-id authentication-mode { simple { key | plain key | cipher cipher-key } | md5 md5-key } command to set the same authentication mode and authentication key.
