Learning Prefixes on the OER Master Controller (MC) - Part 2

I enable learning on the OER Master.

oer master

learn

throughput
delay

I examine the ‘Learn Settings’s 

R4#s oer master | b Learn Settings

Learn Settings:

  current state : SLEEP

  time remaining in current state : 6957 seconds

  throughput

  no delay

  no inside bgp

  no protocol

  monitor-period 5

  periodic-interval 120

  aggregation-type prefix-length 24

  prefixes 100

  expire after time 720

I notice the OER Master is 'sleeping' i.e. not learning prefixes. By default the OER master learns for 5 mins and then sleeps for 120 minutes!  To increase the frequency of OER master learning from the default settings I adjust the monitor period (length of time MC learns prefixes) and the periodic-interval (time between monitoring periods).

oer master

learn

monitor-period 1

periodic-interval 0

I generate some traffic from the MC to R9

ip sla 1

 icmp-echo 9.9.9.9

 frequency 10

ip sla schedule 1 life forever start-time now

ip sla 2

 tcp-connect 9.9.9.9 23 source-ip 1.1.1.1

 timeout 500

 frequency 2

ip sla schedule 2 life forever start-time now

On R9

Ip sla responder

I now check the MC is learning about this prefix

R4#show oer master prefix learned throughput

OER Prefix Statistics:

 Pas - Passive, Act - Active, S - Short term, L - Long term, Dly - Delay (ms),

 P - Percentage below threshold, Jit - Jitter (ms),

 MOS - Mean Opinion Score

 Los - Packet Loss (packets-per-million), Un - Unreachable (flows-per-million),

 E - Egress, I - Ingress, Bw - Bandwidth (kbps), N - Not applicable

 U - unknown, * - uncontrolled, + - control more specific, @ - active probe all

 # - Prefix monitor mode is Special, & - Blackholed Prefix

 % - Force Next-Hop, ^ - Prefix is denied

My next post is on how to get the MC to choose the best route.
