Hi,
This is a question about the task 8.2 of IEWB 10 valume 1.
I will paraphrase the question so those who do not have the
current verison of IEWB can have an idea about I am talking
about.
The question is asking to configure two routers R3 and R4
so that 200Kbps of VoIP traffic always get dequeued first when
it is sent over the FR.
F3 --FR cloud-- F4
FR circuit is provisioned at 256kbps and both routers are
already configured to conform to this rate.
My answer to this question is as follows.
###my answer###
class-map match-all voip
match protocol vofr
policy-map voip-p
class voip
priority 200
map-class frame-relay DLCI403
service-policy output voip-p
(config for the other router is omitted)
###end-of-my-answer###
But the solution guide says
###solution guide answer###
ip access-list extended voip-a
permit udp any any range 16384 32767
class-map match-all voip
match access-groupname voip-a
policy-map voip-p
class voip
priority 200
map-class frame-relay
frame-relay mincir 256000
service-poilcy output voip-p
###end of solution guide's answer###
My question,
1. Is the traffic matched by the statement "match protocol vofr" different
from
the traffic match by the ACL "permit udp any any range 16384 32767"?
2. Why is it necessary to configure "frame-relay mincir 256000"?
Best,
Ken
