Given ((diagram with R1 SLA config)) with configuration written on Picture as
R(Config)#ip sla 1 R1(Config-ip-sla)#icmp-echo 172.20.20.2 source-interface f1/0 R1(Config-ip-sla)#frequency 10 R1(Config-ip-sla)#threshold 100 R1(Config)#ip sla schedule 1 start-time now life forever R1(Config)#track 10 ip sla ???- R1(Config)#ip route 0.0.0.0.0 0.0.0.0 172.20.20.2
What make default route not removed when SLA state down or failed?
A. the destination must be 172.30.30.2 for icmp-echo
B. the threshold value is wrong
C. missing of track feature on default static route command
Correct Answer: C
Remember: If you want to use the “state”, remember that the “track state” will be down also if the the threshold is reached.
Note: with Cisco IOS Release 12.4(20)T, 12.2(33)SXI1, 12.2(33)SRE and Cisco IOS XE Release 2.4, the track rtr command is replaced by the track ip sla command. See the track ip sla command for more information.
