Router Redundancy Using XRRP
Configuring XRRP
master-transition – signifies that the router state has changed specifically
to the master state. The trap sent would contain the domain-number,
router-number, and state information.
authentication-failure – signifies that the virtual router instance has
received an XRRP packet with an authentication mismatch. The trap sent
would contain the domain-number, router-number, and virtual router
instance ID (virtual router owner number and VLAN ID) of the virtual
router that detected the error.
To enable all the traps, use the command xrrp trap all.
To disable the traps, use the no form of the command, with the trap name
to disable a specific trap or with all to disable all the traps. By default, all
the traps are disabled.
[no] xrrp instance < owner-router-number > < vlan-id >
This command configures the virtual router interface on the router. The
virtual router interface (XRRP instance) is identified by the owner-router-
number and the vlan-id. The owner-router-number is the XRRP router
number of the router that owns the IP address(es). The vlan-id identifies
the VLAN on which the XRRP instance is running.
Required Parameters – For each router in the Protection Domain, an
xrrp instance command must be entered for each of the following:
• To create each virtual router interface for the physical router being
configured, you would enter an xrrp instance command with the router
number and the VLAN ID for that interface. For example, to create a
virtual router interface in VLAN 5 for the router that has the XRRP
router number 1, you would enter the following command:
xrrp instance 1 5
• To specifically identify the virtual router interfaces on the other
router in the Protection Domain, you would enter an xrrp instance
command with the ip parameter. For example, on Router-1 in VLAN
5, to identify the virtual router interface on Router-2 that has the IP
address 10.1.1.2 and mask length 24, you would enter the following
command:
xrrp instance 2 5 ip 10.1.1.2/24
For the instance command that creates the virtual router interface on
the router being configured, the ip parameter must not be specified.
These XRRP instances, which are being configured on the router that
owns the IP address, automatically use the IP address of the VLAN on
the router being configured.
