Virtual MAC Address : 00:00:5e:00:01:01 Version : version-3 Priority : 200 Preempt : Hold-time : Authentication : no-authentication Virtual IP address : 10.1.1.1 master-transitions : 1 advertise-rcvd : 0 advertise-interval-errors : 0 ip-ttl-errors : 0 priority-zero-pkts-rcvd : 0 priority-zero-pkts-sent : 0 invalid-type-pkts-rcvd : 0 address-list-errors : 0 pkt-length-errors : 0 Authentication Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes. When you enable authentication, OS10 includes the password in its VRRP transmission. The receiving router uses that password to verify the transmission. You must configure all virtual routers in the VRRP group with the same password. You must enable authentication with the same password or authentication is disabled. Authentication for VRRPv3 is not supported. 1 Create a virtual router for the interface with the VRRP identifier in INTERFACE mode, from 1 to 255. vrrp-group vrrp-id 2 Configure a simple text password in INTERFACE-VRRP mode. authentication-type simple-text text simple-text text - Enter the keyword and a simple text password. Configure VRRP authentication OS10(config)# interface ethernet 1/1/5 OS10(conf-if-eth1/1/5)# vrrp-group 250 OS10(conf-eth1/1/5-vrid-250)# authentication simple-text eureka Verify VRRP authentication configuration OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# vrrp-group 1 OS10(conf-eth1/1/1-vrid-1)# authentication simple-text dell Disable preempt Prevent the Backup router with the higher priority from becoming the master router by disabling the preemption process. The preempt command is enabled by default. The command forces the system to change the master router if another router with a higher priority comes online. You must configure all virtual routers in the VRRP group with the same settings. Configure all routers with preempt enabled or configure all with preempt disabled. 1 Create a virtual router for the interface with the VRRP identifier in INTERFACE mode, from 1 to 255. vrrp-group vrrp-id 2 Prevent any backup router with a higher priority from becoming the Master router in INTERFACE-VRRP mode. no preempt Disable preempt OS10(config)# interface ethernet 1/1/5 OS10(conf-if-eth1/1/5)# vrrp-group 254 OS10(conf-eth1/1/5-vrid-254)# no preempt 608 Layer 3
