F/R (PQ & MQC mix)

Q. What the heck is F/R EEK?
A. frame-relay end-to-end keepalive

F/R PQ & MQC mix:

Here is the only config I know to accomplish this piece of twisted mocklab torture.

Environment:

Router Y has a F/R connection to router A (no sub-interfaces allowed).

Task on page Z:

Configure the following on Serial X on router Y
frame size 64 – 127 = 28%
frame size 128 – 255 = 10%
frame size 256 – 511 = 18%
frame size 512 – 767 = 9%
frame size 768 – 1024 = 6%
the rest WFQ

Task on page Z+10:

Configure router Y so that precedence internet traffic ends up in a high priority queue on link to router A (happens to be Serial X…)

Solution:

class-map match-all 64-127
_match packet length min 64 max 127
class-map match-all 128-255
_match packet length min 128 max 255
class-map match-all 256-511
_match packet length min 256 max 511
class-map match-all 512-767
_match packet length min 512 max 767
class-map match-all 768-1024
_match packet length min 768 max 1024
