336 Configuring Routingw w w . d e l l . c o m | s u p p o r t . d e l l . c o m Configuring VRRPVirtual Router Redundancy Protocol (VRRP) specifies an elector protocol that dynamically assignsrouting responsibility to one of the VRRP routers on the LAN (the master router). The electionprocess enables dynamic failover of routing responsibility in case the master router becomesunavailable.The advantage of VRRP is that it eliminates the single-point-failure phenomenon inherent to therouting environment by providing a higher availability default path, while eliminating the need forconfiguration of dynamic routing or router discovery protocols on every end-host.The Virtual Router Redundancy Protocol (VRRP) page sets the switch’s VRRP routingparameters. To open the Virtual Router Redundancy Protocol (VRRP) page, click Router →Global Routing Parameters→VRRP in the tree view.Figure 8-3. Virtual Router Redundancy Protocol (VRRP) PageInterface — Interface type and number attached to the VRRP router.VRID (1-255) — Virtual router identifier.Priority (1-255) — Router priority used for the virtual router election process. The value maydetermine if a higher priority VRRP router overrides a lower priority VRRP router.Primary IP Address — Virtual IP address identified with the virtual router. The primary IP Addressis selected from actual interface addresses configured on a VRRP router.Master IP Address — The VRRP router that is currently master for this virtual router.State — The current router state. Possible values are:Master — The router functions as the forwarding router for the IP addresses associated withthe virtual router. The master router responds to ARP requests with associated IP addresses inthe ARP target, forwards packets with Virtual MAC Address (VMAC) as the destination
