Virtual Router Redundancy Protocol (VRRP) | 1105Figure 55-8. Command Example Display: show vrrpConfigure VRRP AuthenticationSimple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes.When authentication is enabled, FTOS includes the password in its VRRP transmission, and the receivingrouter uses that password to verify the transmission.Configure simple authentication with the following command in the VRRP mode:Note: All virtual routers in the VRRP group must be configured the same: authentication must be enabledwith the same password or authentication is disabled.Task Command Syntax Command ModeConfigure a simple text password. authentication-type simple[encryption-type] passwordParameters:encryption-type: 0 indicates unencrypted; 7indicates encryptedpassword: plain textINTERFACE-VRIDFTOSshow vrrp------------------GigabitEthernet 1/1, VRID: 111, Net: 10.10.10.1State: Master, Priority: 255, Master: 10.10.10.1 (local)Hold Down: 0 sec, Preempt: TRUE, AdvInt: 1 secAdv rcvd: 0, Bad pkts rcvd: 0, Adv sent: 2343, Gratuitous ARP sent: 5Virtual MAC address:00:00:5e:00:01:6fVirtual IP address:10.10.10.1 10.10.10.2 10.10.10.3 10.10.10.10Authentication: (none)------------------GigabitEthernet 1/2, VRID: 111, Net: 10.10.2.1State: Master, Priority: 125, Master: 10.10.2.1 (local)Hold Down: 0 sec, Preempt: TRUE, AdvInt: 1 secAdv rcvd: 0, Bad pkts rcvd: 0, Adv sent: 601, Gratuitous ARP sent: 2Virtual MAC address:00:00:5e:00:01:6fVirtual IP address:10.10.2.2 10.10.2.3Authentication: (none)FTOS(conf)#
