irule & advanced routing module

Have been looking into advanced routing modules.

 

Would like to change cost of a route (or only send the route) for a vip address based on what nodes is up i.e.

 

if node a is up and b is down send route as normal

 

if node a is down and b is up make route higher cost (or do not send route)

 

 

From what I read, Route health injection is based on if vip is up so not exactly what I require.

 

 

I know I can check node status with irule. Can I influence advanced routing module with irule?

 

A link to an example irule and routing would be great.

 

 

thanks

    Hi Peter,

     

    Have you looked into the following Video Blog. I am not sure if this entirely answers your problem but it could give you an idea of what it can do. However, I don't believe you can manipulate the routing in the manner you speak of directly with an iRule. It probably can be manipulated with some custom monitors which could trigger a shell script and inturn the shell script could make some route changes based on that.

     

     

    Here is the link to the video

    I hope this helps,
