Multiple Masters Coexist in a VRRP Group

Multiple Masters Coexist in a VRRP Group

Fault Description

Multiple masters coexist in a VRRP group.


  1. 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.

  2. 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 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 key.


      For security purposes, you are advised to use MD5 as the authentication algorithm of VRRP.
