VRRP/3/VRRP_DOUBLE_MASTER_ERR
Message
VRRP/3/VRRP_DOUBLE_MASTER_ERR:VRRP detected double masters. (IfIndex=[IfIndex], IfName=[IfName], VrId=[VrId], PeerIp=[SrcIpAddr], PeerPriority=[PeerPriority])
Parameters
| Parameter Name | Parameter Meaning |
|---|---|
| IfIndex | Interface index. |
| IfName | Interface name. |
| VrId | ID of a VRRP group. |
| PeerIp | Primary IP address of the remote interface where a VRRP group running IPv4 resides. |
| PeerPriority | Priority of the VRRP group on the remote interface. |
Possible Causes
Possible causes are as follows:
The local VRRP group failed to send out VRRP packets.
The VRRP packets sent by the local VRRP group were discarded due to overloaded links.
The configurations (authentication mode, authentication key, and list of virtual IP addresses, and protocol version numbers) of the local and remote VRRP groups are different.
Procedure
- Run the debugging vrrp { state | packet | timer } [ interface interface-type interface-number [ vrid virtual-router-id ] ] command to check the reason why VRRP packets failed to be sent out.
- Run the display vrrp verbose command to check whether the authentication modes and authentication keys on the local and remote ends are the same. If they are different, run the vrrp vrid virtual-router-id authentication-mode { simple { [ plain ] key | cipher cipher-key } | md5 md5-key } command to reconfigure the authentication mode for VRRP packets.
- Run the display vrrp command to check whether the virtual IP addresses and the number of virtual IP addresses of the local VRRP roup are the same as that of the remote VRRP group. If they are different, run the vrrp vrid virtual-router-id virtual-ip virtual-address command to reconfigure a virtual IP address for the VRRP group.
- Run the display vrrp protocol-information command to check whether the protocol version numbers at both ends are the same. If the protocol version numbers are different, run the vrrp version { 2 | 3 } command to reconfigure the protocol version number.
- End.
