f. Enable the probe to react to the test-failure event and the test-completion
event.
You must configure both the test-failure and test-completion reaction
conditions to use next-hop verification. For information, see "Setting Reaction
Conditions" on page 70.
host1(config)#rtr reaction-configuration 10 test-failure 3
host1(config)#rtr reaction-configuration 10 test-completion
g. Schedule the probe operation. For information, see "Scheduling the Probe"
on page 72.
host1(config)#rtr schedule 10 life 3
host1(config)#rtr schedule 10 restart-time 1
host1(config)#rtr schedule 10 start now
Repeat Step 4 to define RTR 11 for Fast Ethernet interface 4/1.
host1(config)#rtr 11
host1(config-rtr)#type echo protocol ipIcmpEcho 10.1.1.2
source fastEthernet 4/1
host1(config-rtr)#receive-interface fastEthernet 4/1
host1(config-rtr)#frequency 1
host1(config-rtr)#samples-of-history-kept 0
host1(config-rtr)#exit
host1(config)#rtr reaction-configuration 11 test-failure 3
host1(config)#rtr reaction-configuration 11 test-completion
host1(config)#rtr schedule 11 life 3
host1(config)#rtr schedule 11 restart-time 1
host1(config)#rtr schedule 11 start now
Establish a static route associated with RTR 10.
This command creates a static route and installs it in the routing table only if
RTR 10 is currently reachable or if no other static route to IP destination address
10.1.1.2 is usable.
host1(config)#ip route 10.1.1.2 255.255.255.255 10.1.1.2 fastEthernet 4/0
verify rtr 10 last-resort
Establish a static route associated with RTR 11.
This command creates a static route and installs it in the routing table only if
RTR 11 is currently reachable or if no other static route to IP destination address
10.1.1.2 is usable.
host1(config)#ip route 10.1.1.2 255.255.255.255 10.1.1.2 fastEthernet 4/1
verify rtr 11 last-resort
When both RTR 10 and RTR 11 are unreachable, you can control which static
route is installed in the routing table by including the last-resort keyword in the
ip route verify rtr command only for the route that you want to install.
