The following example shows viewing VRRP session state information. The bold line shows the VRRP BFD session. R1(conf-if-te-4/25)#do show vrrp TenGigabitEthernet 4/1, VRID: 1, Net: 2.2.5.1 State: Backup, Priority: 1, Master: 2.2.5.2 Hold Down: 0 sec, Preempt: TRUE, AdvInt: 1 sec Adv rcvd: 95, Bad pkts rcvd: 0, Adv sent: 933, Gratuitous ARP sent: 3 Virtual MAC address: 00:00:5e:00:01:01 Virtual IP address: 2.2.5.4 Authentication: (none) BFD Neighbors: RemoteAddr State 2.2.5.2 Up Changing VRRP Session Parameters BFD sessions are configured with default intervals and a default role. The parameters that you can configure are: Desired TX Interval, Required Min RX Interval, Detection Multiplier, and system role. You can change parameters for all VRRP sessions or for a particular neighbor. To change parameters for all VRRP sessions or for a particular VRRP session, use the following commands. • Change parameters for all VRRP sessions. INTERFACE mode vrrp bfd all-neighbors interval milliseconds min_rx milliseconds multiplier value role [active | passive] • Change parameters for a particular VRRP session. INTERFACE mode vrrp bfd neighbor ip-address interval milliseconds min_rx milliseconds multiplier value role [active | passive] To view session parameters, use the show bfd neighbors detail command, as shown in the example in Verifying BFD Sessions with BGP Neighbors Using the show bfd neighbors command example in Displaying BFD for BGP Information. Disabling BFD for VRRP If you disable any or all VRRP sessions, the sessions are torn down. A final Admin Down control packet is sent to all neighbors and sessions on the remote system change to the Down state. To disable all VRRP sessions on an interface, sessions for a particular VRRP group, or for a particular VRRP session on an interface, use the following commands. • Disable all VRRP sessions on an interface. INTERFACE mode no vrrp bfd all-neighbors Bidirectional Forwarding Detection (BFD) 162
