Re: OER master active-probe

Hi Marc,

The policy-rules command tells the oer master process to use the oer-map specified elsewhere. Whether active probing is being used or not depends on your monitor mode which can be set in the oer-map. If it's not set in the oer-map I think it would fall back to whatever is set in global policy.

So from the initial config you posted there should be a section starting with "oer-map prfx" that is separate to the "oer master" section.

cheers,
Ben.

Thanks that was the issue. I guess my other question for more clarity
in the configuration...

what exactly is
policy-rules prfx

doing and is this linked to the oer-map active probing?

Thanks,

Marc

From what I hdvh seen....

I would say it is a Must to put set mode monitor active under oer-map for
particular prefix

R6#sh run | b ^oer-map

R6#sh oer master active-probes
        OER Master Controller active-probes
Border = Border Router running this Probe

Prefix = Probe is assigned to this Prefix

Target = Target Address
TPort = Target Port

The following Probes exist:

State Prefix Type Target TPort How
Codec
Assigned 3.3.3.3/32 echo 3.3.3.3 N Cfgd
N

The following Probes are running:

Border State Prefix Type Target TPort
1.1.1.6 ACTIVE 3.3.3.3/32 echo 3.3.3.3 N

Thanks,
