Reliable Static Routing Backup Using Object Tracking Issue

[shawvoel]

Hi All expert,

I was trying to implement this feature in our environment, so that I configure my 2 routers with this feature. I'd configure a loopback interface for the tracking IP. But when the primary link (route) is fail, it can't output the traffic to second link, I can see the routing table is change to second route, but the traffic can't go through, can anyone point me the mistake I'd made?

Thank you.

hi,

ur n/w topology is like this i guess.

r1--r2

x |

| |

| |

r3-xr4

(x is ur back up link)

correct?

[shawvoel]

Yes, correct.

Can you please kindly point me my error on the configuration?

Because the first link down, second link can't ping to destination. But from the routing table I can see the second route was in place.

Please help.

Hi Shawvoel

try removing this command

access-list 101 permit icmp any host 172.16.1.1 echo

!

route-map MY_POLICY permit 10

match ip address 101

set interface Null0

set ip next-hop 192.168.1.2

and let me know

Check to see if R4 has routes back to the other subnets, I mean the backup link subnets.

Please if you can paste R2 and R3 config as well so I can understand what are you trying to do.

Thanks,

Please help to identify the issue.

Thank you.

Hi jitesh,

Yes, I'd try this, but the object tracking will sometime up & sometime down status when I show "show ip route track-table".

I can't figure out why the tracking will still up even I shut down the interface.

Here I attach the rest of the router config.

Thank you.
