Associated IP Addresses

The Virtual Router Redundancy Protocol (VRRP) eliminates the single point of failure inherent in the static default routed environment. VRRP specifies an election protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN. The VRRP router controlling the IP addresses associated with a virtual router is called the Master, and forwards packets sent to these IP addresses. The election process provides dynamic fail-over in the forwarding responsibility should the Master become unavailable. Any of the virtual router's IP addresses on a LAN can then be used as the default first hops router by end-hosts.

You use the Associated IP Addresses pane to configure the VRRP. An entry in the table contains an IP address that is associated with a virtual router. The number of rows for a given ifIndex and VrId equal the number of IP addresses associated (for example, backed up) by the virtual router (equivalent to 'vrrpOperIpAddrCount').

To set up the associated IP addresses

1.	From the AppDirector menu, select Redundancy > VRRP > Associated IP Addresses. The Associated IP Addresses pane displays.

2.	Click Create. The Associated IP Addresses Create pane displays.

3.	Set the parameters.

 

Parameter	Description
IP Version	Select IPv4 or IPv6.
If Index	Displays the interface number.
VR ID	Displays the virtual routers identification number. Note: VR ID must be Disabled to add Associated IP addresses to it. Then VR ID must be Enabled. The VR ID is set in the Virtual Routers table.
Associated IP	Displays the IP address associated with this VR ID. Note: Up to 255 IP addresses can be associated with a single VR ID.

4.	Click Set.
