LTM Traceroute for non-default ROUTE PARTITION

I’m trying to run a cron job on LTM to perform a traceroute to a specific host an log the results. The problem I have is that this command must be run from a specific ROUTE DOMAIN.

 

[root@ka-lb05:Active:In Sync] config rdsh 1 <- this changes to ROUTE DOMAIN 1 (note trace fails from ROUTE DOMAIN 0)

 

[root@ka-lb05:Active:In Sync] config rdsh 1 <- this changes to ROUTE DOMAIN 1 (note trace fails from ROUTE DOMAIN 0) traceroute to 217.21.139.34 (217.21.139.34), 30 hops max, 40 byte packets

13 (217.21.139.34) 69.957 ms 71.974 ms 73.237 ms

 

[root@ka-lb05:Active:In Sync] config

 

[root@ka-lb05:Active:In Sync] config [root@ka-lb05:Active:In Sync] config exit <- exits back to ROUTE DOMAIN 0 exit [root@ka-lb05:Active:In Sync] config

 

Here is my script:

 

[root@ka-lb05:Active:In Sync] scripts cat latencytest

 

!/bin/bash

echo hello <- print hello before changing to ROUTE DOMAIN 1

 

rdsh 1 <- change to ROUTE DOMAIN 1

 

tracert -T -p 443 217.21.139.34

 

exit <- go back to ROUTE DOMAIN 0

 

However, the trace does not work. Here is what it looks like.

 

[root@ka-lb05:Active:In Sync] scripts ./latencytest <- command that calls the script

 

hello <- echos hello

 

[root@ka-lb05:Active:In Sync] scripts <- nothing happens

 

[root@ka-lb05:Active:In Sync] scripts <- nothing happens

 

[root@ka-lb05:Active:In Sync] scripts exit <- I enter exit at the prompt

 

exit

 

traceroute to 217.21.139.34 (217.21.139.34), 30 hops max, 40 byte packets <- traceroute starts...appears to run from ROUTE DOMAIN 0

 

1 * * *

 

2 * * *

 

3 * * *

 

4 * * *

 

Is there something I need to do to get this to work?

    Hi, No Pro here but maybe you can use this: rdexec - The rdexec utility allows you to perform a single command for the specified route domain instead of converting the IPv4 IP address argument to an IPv6 IP address argument before using it as an argument for the command. For example: rdexec [] Anyway did you tried tracert IP%RDID? Is that not working as well? What is TMOS version? Piotr

    Hi Dale, Piotr is right (+1). rdexec is the tool to use, imho. I´m using it since a couple of months successfully with an external monitor (openssl s_client with server name indication required) in combination with routing domains. Thanks, Stephan
