OER: How to configure Active probe ?

AndiS

Topology :  Rx--MC  --- BR1 ---- Ry

                              --- BR2 ----

I want MC to ACTIVEly probing for best exit from Rx to Ry but i cannot get the OER active probe working.

 

This's my active probe configuration (assuming basic OER config is in place):

BR 1&2:

 oer border

       active-probe address source interface Loopback0

MC:

  oer master

       mode route control

       mode monitor active

       active-probe echo <Ry>

 

Ry:

    ip sla responder                    // i don't see icmp echo trigger from BR1 or BR2 ??

 

I try using oer-map but also not working

 MC :  ip access-list extended Rx-Ry permit ip host <Rx> host <Ry>

          oer-map OER

               match ip address access-list Rx-Ry

               set active-probe echo <Ry>

         oer master 

               policy-rules OER

 

What i'm missing here ? can somebody give a hint ? thanks.

Hi AndiS

Active probes are only sent once every 60 seconds.  Have you tried debug ip icmp on the MC to see if the MC or the border routers are sending them once per minute?

I found my own culprit, I should set manually monitor active on  oer-map

           oer-map OER 10

               match ip address access-list Ry

               set mode monitor active                                  // i thought it will take global config automatically

               set active-probe echo <Ry>
