dmvpn / mGRE qos setting

have a question regarding the QoS bandwidth for the DMVPN /mGRE interface

simple configuration

 

interface GigabitEthernet0/0/0
description ISP_FACING
bandwidth 100000

!-------------------------------

interface Tunnel11
description PRIMARY_TUNNEL
bandwidth 100000

.....

nhrp map group QOS_GROUP service-policy output MAIN_QOS_POLICY
qos pre-classify
bfd template BFD_TUNNEL
tunnel source GigabitEthernet0/0/0
tunnel mode gre multipoint

!-------------------------------

policy-map SUB_QOS_POLICY
class CM_VOICE-TRAFFIC
priority percent 20
class CM_BUSINESS-CRITICAL-TRAFFIC
bandwidth percent 20
random-detect
queue-limit 1024 packets
class CM_STANDARD-TRAFFIC
bandwidth percent 50
random-detect
queue-limit 1024 packets
class class-default
policy-map MAIN_QOS_POLICY
class class-default
shape average percent 100
service-policy SUB_QOS_POLICY
!----------------------------------

 

the question is 

I set up full mesh nhrp 

with this interface, I am connected to 5 spoke (or hub since I do full mesh nhrp configuration) , and they are in difference actual thoughput (e.g. some are 20 Mbps links some are 50 Mbps links)

since QoS for multipoint connection and the QoS policy are per-endpoint, will QoS policy think I have 100Mbps x 5 bandwidth?

 

can I set up a QoS Policy which will limit my egress as 100Mbps?

Hello Perkin,

you have opened also another trhead on this same argument.

Follow the answers provided there.

 

>> with this interface, I am connected to 5 spoke (or hub since I do full mesh nhrp configuration) , and they are in difference actual thoughput (e.g. some are 20 Mbps links some are 50 Mbps links)

 

You need to use two different NHRP groups one for the spokes with 50 Mbps link and one for the spokes  with 20 Mbps links.

The two parent policy are shaper that limit to 50 Mbps and to 20 Mbps respectively.

Do not use a line like the following in the parent shaper as one instance of it is created for each spoke in the group

shape average percent 100

 

use

shape average 50000000          

 

and

shape average 20000000

 

Hope to help

Giuseppe
