Router Redundancy Using XRRP 
Configuring XRRP 
Customizing the XRRP Configuration 
To customize the XRRP configuration, use any of the following XRRP 
command options at the CLI global configuration level: 
Syntax:  xrrp domain < 1-16 > 
no xrrp 
xrrp [ router < 1-2 >] 
xrrp failback < 10-999 > 
xrrp trap < trap-name | all > 
xrrp instance < owner-router-number > < vlan-id > [advertise < 1-60 > | 
authentication < auth-string > | ip < ip-addr/mask-length >] 
xrrp domain < 1-16 > 
This command sets the XRRP Protection Domain that the router is in. The 
router can be in only one domain. The default value is 1. This value cannot 
be changed if there is at least one virtual router instance running on the 
router. To change the value after XRRP is operating, you must first disable 
XRRP (use the no xrrp command). 
xrrp router < 1-2 > 
This command sets the unique number for the router within a given 
Protection Domain. No two routers in the same Protection Domain can 
have the same router number. The default value is 1. 
This value cannot be changed if there is at least one virtual router instance 
running on the router. To change the value after XRRP is operating, you 
must first disable XRRP (use the no xrrp command).
