We will configure the SLA tracking for R2 with the condition as R2 should be master unless ping response time to 150.100.220.7 exceeds 80 MS.
So we have configured the R2 with our above requirement:
track 2 rtr 1
!
ip sla monitor 1
type echo protocol ipIcmpEcho 150.100.220.7
threshold 80
int f1/0
vrrp 1 ip 150.100.12.100
vrrp 1 priority 105
vrrp 1 track 2
We got below messages once above configuration done.
*Sep 20 22:18:20.107: %SYS-5-CONFIG_I: Configured from console by conso
*Sep 20 22:18:22.287: %VRRP-6-STATECHANGE: Fa1/0 Grp 1 state Master -> Backup
Checking the ping response:
R2#ping 150.100.220.7
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 150.100.220.7, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/9/12 ms
So now we enable the SLA tracking and observe what happens?
R2(config)#ip sla monitor schedule 1 start-time now
R2(config)#
*Sep 20 22:20:04.883: %VRRP-6-STATECHANGE: Fa1/0 Grp 1 state Backup -> Master
R2(config)#
So now finally our R2 is master because MS time is below 80, if it exceeds above 80 then R2 will loose its master role and again will fall in backup sate.
