RTR tracking without IP SLA feature

Hi

We are using the following image on our production layer-3 switch

Code:

IOS (tm) s72033_rp Software (s72033_rp-IPSERVICESK9_WAN-M), Version 12.2(18)SXF11, RELEASE SOFTWARE (fc1)

There is no support for IP SLA in the current version. But it seems there is no support for "track 2 rtr 10 reachability" and "ip route x y z track 1" type of commands either. While the following commands are accepted

Code:

# rtr 10
          # type echo protocol ipIcmpEcho 10.10.10.10
          # frequency 2 
          # request-data-size 32
          # timeout 1000
                        
# rtr schedule 10 life forever start-time now

How to make the following work on the current IOS. Is there an alternative to achieve the same or is IOS upgrade a must???

Code:

# track 2 rtr 10 reachability 
# track 1 list boolean and
          # object 2 not
                        
ip route 11.11.11.0 255.255.255.0 12.12.12.12 track 1

P.S. The objective is to install a static route for network 11.11.11.0/24 towards 12.12.12.12 when the device at 10.10.10.10 (not directly connected) is NOT reachable. This will be backup route for the remote 10 network. We don't have dynamic routing or vpn in between. Any ideas??

Thanks.

 

Solution

Got the solution from another forum.

For the benefit of others, I am pasting the sample config in here.

Code:

rtr 10
  type echo protocol ipIcmpEcho 10.10.10.10
  timeout 1000
  frequency 3
  request-data-size 32
rtr schedule 10 life forever start-time now

Explanation for OID value can be found here

The last .10 in the OID value is your RTR (or IP SLA) number.
