3.6 Reliable Static Routing with Enhanced Object Tracking

All,

I believe I have configured task 3.6 correctly (my config matches up with the solution) but I am not seeing R4 fail over to the frame connection correctly when the tracked object stops responding.

I do see the static route pointing out the ethernet interface get removed and the static route with AD=2 pointing out the FR interface is installed into the routing table:

 

Rack1R4#debug ip routing

 

*Mar  1 06:25:19.606: %TRACKING-5-STATE: 1 rtr 1 state Up->Down

Rack1R4#

*Mar  1 06:25:19.606: RT: del 150.1.1.0/24 via 155.1.146.1, static metric [1/0]

*Mar  1 06:25:19.610: RT: delete subnet route to 150.1.1.0/24

*Mar  1 06:25:19.614: RT: NET-RED 150.1.1.0/24

*Mar  1 06:25:19.618: RT: add 150.1.1.0/24 via 155.1.0.5, static metric [2/0]

*Mar  1 06:25:19.622: RT: NET-RED 150.1.1.0/24


But at this point I can't ping R1's loopback even though I am supposed to be able to.



Rack1R4#debug ip packet



*Mar  1 06:29:30.578: IP: tableid=0, s=155.1.0.4 (local), d=150.1.1.1 (FastEthernet0/1), routed via FIB

*Mar  1 06:29:30.582: IP: s=155.1.0.4 (local), d=150.1.1.1 (FastEthernet0/1), len 100, sending.







So, even though it is sourcing the ping correctly from the serial interface's IP address, it is still trying to send it out the fa0/1 interface. Am I reading that right? Does anyone know why this is?

 



If I do a quick 'shut' and 'no shut' on the fa0/1 interface, that fixes it:



Rack1R4#debug ip pack

IP packet debugging is on

Rack1R4#ping 150.1.1.1


Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 150.1.1.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/32/40 ms

Rack1R4#

*Mar  1 06:31:16.638: IP: s=155.1.0.4 (local), d=150.1.1.1 (Serial0/0.1), len 100, sending

*Mar  1 06:31:16.666: IP: tableid=0, s=150.1.1.1 (Serial0/0.1), d=155.1.0.4 (Serial0/0.1), routed via RIB

*Mar  1 06:31:16.670: IP: s=150.1.1.1 (Serial0/0.1), d=155.1.0.4 (Serial0/0.1), len 100, rcvd 3



Thanks!
