VRRP/3/VRRP_DOUBLE_MASTER_ERR: VRRP detected double masters. (IfIndex=[IfIndex], IfName=[IfName], VrId=[VrId], PeerIp=[SrcIpAddr], PeerPriority=[PeerPriority])
| Parameter Name | Parameter Meaning |
|---|---|
|
IfIndex |
Interface index |
|
IfName |
Interface name |
|
VrId |
ID of a VRRP group |
|
SrcIpAddr |
Primary IP address of the remote interface where a VRRP group running IPv4 resides |
|
PeerPriority |
Priority of the VRRP group on the remote interface |
Cause 1: The local VRRP group failed to send out VRRP protocol packets.
Cause 2: The VRRP protocol packets sent by the local VRRP group were discarded due to overloaded links.
Cause 3: The configurations (authentication mode, authentication key, and list of virtual IP addresses) of the local and remote VRRP groups are different.
1. Run the debugging vrrp command to check the reason why VRRP packets are not sent.
2. Run the display cpu-defend car protocol vrrp statistics slot slot-id command to check whether the link is overloaded.
3. Run the display vrrp command to check whether the authentication modes and authentication keys on both ends are the same. If not, 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. The MD5 encryption algorithm has low security and has security risks.
4. Run the display vrrp command to check whether the virtual IP addresses and the number of virtual IP addresses are the same. If not, run the vrrp vrid virtual-router-id virtual-ip virtual-address command to reconfigure the virtual IP address of the VRRP group.
5. End.
