Routerconfiguration:C2(su)‐>router(Config‐router)#
Usage
IfthevirtualrouterIPaddressisthesameastheinterface(VLAN)addressownedbyaVRRP
router,thentherouterowningtheaddressbecomesthemaster.Themastersendsan
advertisementtoallotherVRRProutersdeclaringitsstatusandassumesresponsibilityfor
forwardingpacketsassociatedwithitsvirtual
routerID(VRID).
IfthevirtualrouterIPaddressisnotownedbyanyoftheVRRProuters,thentherouterscompare
theirprioritiesandthehigherpriorityownerbecomesthemaster.Ifpriorityvaluesarethesame,
thentheVRRProuterwiththehigherIPaddressisselectedmaster.

Example
Thisexampleshowshowtoconfigureavirtualrouteraddressof182.127.62.1ontheVLAN1
interface,VRID1,andtosettherouterconnectedtotheVLANviathisinterfaceasthemaster:
C2(su)->router(Config)#router vrrp
C2(su)->router(Config-router)#address vlan 1 1 182.127.62.1 1
