Router Redundancy Using XRRP 
Messages Related to XRRP Operation 
Messages Related to XRRP Operation 
These messages appear in the Event Log and, if Syslog Debug is configured, 
in the designated Debug destinations. 
Message  Meaning 
Unable to alloc a msg buffer from 
routine < routine name > 
Duplicate IP address < ip-addr > 
detected 
IP address < ip-addr > in use, XRRP 
cannot take over 
Cannot add MCAST address 
< xx-xx-xx-xx-xx-xx > 
No IP address configured for VR on 
rtr < router-num >, vid < vid-number > 
Indicates that a message buffer could not be 
allocated. Although XRRP can handle this event in this 
case, it does indicate that the system is critically low 
on message buffers and will probably crash soon. 
Indicates that a duplicate IP address has been 
detected on the network for an enabled secondary 
address. XRRP will relinquish control of the address 
to correct the duplicate IP address situation. This can 
happen when XRRP is disabled on one router, but not 
disabled on its peer. 
Indicates that some other device on the network 
currently has the IP address configured and XRRP 
wanted to take control of this secondary address. 
XRRP will not  take over the address until this situation 
has been corrected so as to avoid the creation of a 
duplicate IP address on the network. It will however 
check at the failover period (3 times the advertisement 
interval) if the situation had been corrected. Note: this 
is only done for secondary addresses. 
Indicates that XRRP initialization has failed since the 
Multicast receive address could not be configured. 
This is a critical internal error and should not occur 
on a healthy switch. 
Indicates that the Virtual router interface on the 
displayed router and VID does not have an IP address 
configured. This can happen to virtual router 
interfaces for secondary addresses, when the 
primary address has been changed.  This error will 
force the remote miss-configuration flag to be set so 
fail-over will only occur when a complete router 
failure occurs. (This indicates router miss-
configuration.)
