If you want to use Layer 3 VSRP, you must enable it by entering the following commandat the CONFIG level.BigIron RX(config)# router vsrpSyntax: [no] router vsrp• If you want to provide Layer 3 redundancy only, you could use VRRP or VRRP-Extended. Youmay use router vrrp or router vrrp-extended as long as router vsrp is not enabled.Configuring optional VSRP parametersThe following sections describe how to configure optional VSRP parameters.Disabling VSRP on a VRIDIf you want to deactivate VSRP on a VRID, enter the following command.BigIron RX(config-vlan-200-vrid-1)# disableSyntax: disableConfiguring authenticationIf the interfaces on which you configure the VRID use authentication, the VSRP packets on thoseinterfaces also must use the same authentication. VSRP supports the following authenticationtypes:• No authentication – The interfaces do not use authentication. This is the default.• Simple – The interfaces use a simple text-string as a password in packets sent on theinterface. If the interfaces use simple password authentication, the VRID configured on theinterfaces must use the same authentication type and the same password.To configure a simple password, enter a command such as the following at the interfaceconfiguration level.BigIron RX(config-if-e10000-1/6)# ip vsrp auth-type simple-text-auth ourpwordThis command configures the simple text password “ourpword”.
