5.8 Virtual Router Redundancy Protocol (VRRP)

Virtual Router Redundancy Protocol (VRRP) specifies a protocol that dynamically elects a gateway router from among virtual routers running VRRP on a LAN. VRRP enables a group of routers to form a single virtual router. The LAN hosts can then be configured with the virtual router as their default gateway. The virtual router, representing a group of routers, is also known as a VRRP group identified by Virtual Router Identity (VRID). This allows hosts to maintain access to other networks without requiring configuration of dynamic routing or router discovery protocols on every end-host. The IC35516 VRRP implementation fully conforms to the virtual router redundancy protocol outlined in RFC 2338.

5.8.1 VRRP Configuration

All VRRP configuration commands are provided within the interface configuration mode.

Router(config-if-veth1)# ip vrrp ? <1-255> Virtual router ID (VRID) Router(config-if-veth1)# ip vrrp 4 ?

 

authentication

Enable authentication

 

description

Set virtual router description

 

ip

Set the IP Address

 

preempt

Enable preempt mode

 

priority

Set priority to specified VRID

Command

 

Purpose

 

ip vrrp VRID ip A.B.C.D

Enables VRRP on an interface and identifies the

 

 

 

 

primary IP address of the virtual router.

 

 

ip vrrp VRID description text

Assigns a text description to the VRRP VRID group.

 

 

 

 

 

 

 

ip vrrp VRID preempt

 

Configures the router to take over as master virtual

 

 

 

router for a VRRP VRID group if it has a higher priority

 

 

 

 

than the current master virtual router. This command is

 

 

 

 

enabled by default.

 

 

ip vrrp VRID priority level

Sets the priority level of the router within a VRRP VRID

 

 

 

 

group. The default value is 100.

 

 

ip vrrp VRID timers [advertise

Configures the interval between successive

 

 

interval]

 

advertisements by the master virtual router in a VRRP

 

 

 

 

VRID group.

 

 

ip vrrp VRID authentication string

Authenticates VRRP packets received from other

 

 

 

 

routers in the VRID group. If you configure

 

 

 

 

authentication, all routers within the VRRP VRID group

 

 

 

 

must use the same authentication string.
