Viewing and inserting VRRPs

Use the VRRP tab to view all configured VRIDs for the switch.

  1. To open the VRRP tab, use on of the following menu options:
    2. ­ On a port, choose Edit > Port > VRRP.
    The Port dialog box opens, and the VRRP tab is displayed.
    ­ On a VLAN, choose VLAN > VLANs > Basic > IP > VRRP.
    The IP, VLAN dialog box opens, and the VRRP tab is displayed.

To insert a VRRP:

  1. In the VRRP tab, click Insert.
    2. The Insert VRRP dialog box opens.
  2. In the VrId text box, type the ID of the virtual router on the VRRP.
  3. In the IpAddr text box, type the IP address of the virtual router interface.
  4. In the Control box, select enabled.
  5. In the Priority text box, type a number between 1 and 255. The default is 100.
  6. In the AdvertismentInterval text box, type the time interval to wait between sending advertisment messages. The default is 1.
  7. In the CriticalIpAddr text box, type the IP Address for a backup virtual router.
  8. In the HoldDownTimer text box, type the time interval to set the VRRP timer.

    Note Note: Nortel Networks recommends that you set all your routers to the identical number of seconds for the Hold Down Timer.

The VRRP tab fields and Insert VRRP dialog box fields for both types of interfaces have the same parameters, and the parameters function the same.


Field Description
Vrid
A number that uniquely identifies a virtual router on a given VRRP router. The virtual router acts as the default router for one or more assigned addresses (1 to 255).
IpAddr
IP address of the virtual router interface.
VirtualMacAddr
(VRRP tab only)
MAC address of the virtual router interface.
State
(VRRP tab only)
The state of the virtual router interface:
  • initialize: waiting for a startup event
  • backup: monitoring availability and state of the master router
  • master: functioning as the forwarding router for the virtual router IP address(es)
Control
Whether VRRP is enabled or disabled for the port or VLAN.
Priority
Priority value to be used by this VRRP router. Set a value from 1 to 255, where 255 is reserved for the router that owns the IP addresses associated with the virtual router. The default is 100.
MasterIpAddr
(VRRP tab only)
The IP address of the physical interface of the master virtual router that has the responsibility of forwarding packets sent to the virtual IP address(es) associated with the virtual router.
AdvertisementInterval
The time interval (in seconds) between sending advertisement messages. Set from 1 to 255 seconds with a default of 1 second. Only the master router sends advertisements.
VirtualRouterUpTime
(VRRP tab only)
The time interval (in hundredths of a second) since the virtual router was initialized.
CriticalIPAddr
An IP interface on the local router configured so that a change in its state would cause a role switch in the virtual router (for example, from master to backup) in case the interface stops responding.
HoldDownTimer
The time interval (in seconds) a router is delayed when changing to master state.
